MAGNITUDE AND FREQUENCY OF FLOODS IN THE UNITED STATES

PART 11. PACIFIC SLOPE BASINS IN CALIFORNIA- COASTAL BASINS SOUTH OF THE KLAMATH RIVER

BASIN AND CENTRAL VALLEY DRAINAGE FROM THEWEST

By L. E. YOUNG and R. W. GRUFF

ABSTRACT

This report presents a method for determing the probable magnitude of floods* for any recurrence interval between 1.2 and 50 years for any stream, gaged or ungaged, in the area studied. This report and a companion report (U.S. Geolog ical Survey Water-Supply Paper 1686) cover the region designated as "Part 11" in the series of Geological Survey reports entitled "Surface Water Supply of the United States." The area covered by this report includes those streams in California that drain into the Pacific Ocean between Mexico on the south and the Klamath River basin on the north, plus those streams that drain from the west into the Central Valley south of the Clear Creek basin. The area has been divided into two regions of differing flood-frequency characteristics.

The hydrologic basin characteristics having the most significant effect on the flood magnitude were drainage area, mean annual precipitation, and altitude. These were used as independent variables to derive equations for determining flood magnitudes with recurrence intervals of 1.2, 2.33, 5, 10, 25, and 50 years. From the equations, flood magnitude-frequency relations can be constructed. The procedure for computing flood magnitude is not applicable at sites where the drainage area is less than 10 square miles or where the usable storage exceeds 4.5 million cubic feet (103 acre-feet) per square mile.

INTRODUCTION

PURPOSE AND SCOPE

This volume is one of a series of flood-frequency reports covering the conterminous United States. The objectives of this report are (1) to present all significant flood-peak data for the region covered by the report and (2) to present relations derived from an analysis of the flood data whereby the flood magnitude and its probability of occur rence at any site on any stream in the area, with certain limitations, can be evaluated. The limitations are discussed in the section of the report titled "Selection of gaging-station records."

2 MAGNITUDE AND FREQUENCY OF FLOODS, PART 11, VOLUME 1

The area covered by this report, volume 1, and a companion report, volume 2, U.S. Geological Survey Water-Supply Paper 1686, com prises the Pacific slope basins in California and is combined in a single report designated Part 11 in the series of reports published by the Geological Survey entitled "Surface Water Supply of the United States." The two volumes are needed in the current nationwide series entitled "Magnitide and Frequency of Floods in the United States" because the flood data for Part 11 are too voluminous to be contained in a single report. Figure 1 shows the Part 11 area in the conterminous United States. The area covered by this report is shaded and includes those streams that drain into the Pacific Ocean between Mexico on the south and the Klamath River basin on the north, plus those streams that drain from the west into the Central Valley south of Clear Creek. The report area, in turn, was divided into two regions. This division was not arbitrary; the regional boundaries were established on the basis of topography, physiography, and flood magnitude-frequency characteristics that are described in this study.

The relation between flood peaks and liydrologic characteristics was investigateed by a multiple-regression analysis of the data. The hydrologic characteristics that were considered included topographic, climatic, and runoff variables. Statistical tests were applied to elim inate those hydrologic characteristics that were not significant. The equations defined are based on a comprehensive study of all flood data available in the area and provide a means for determining the most probable flood magnitude for any recurrence interval between 1.2 and 50 years, within the scope of the data.

Flood-peak data through the 1965 water year for gaging stations with 5 years or more of record prior to the 1964 water year are tabu lated in this report, and, in addition, significantly large flood peaks at miscellaneous sites and at gaging stations with less than 5 years of record are included.

INTRODUCTION


The streamflow records used, unless otherwise stated, were collected by the U.S. Geological Survey in cooperation with many Federal, State, county, and municipal agencies. Detailed acknowledgment of cooperation is given in the series of water-supply papers published by the Geological Survey entitled "Surface Water Supply of the United States, Part 11, Pacific slope basins in California."

FLOOD-FREQUENCY ANALYSIS

Flood data can be analyzed as an annual flood series or as a partial- duration series. An annual flood series consists of the highest momen tary peak discharge for each water year. A partial-duration series includes all peaks above a selected base discharge, regardless of their relation to a given time period. The two methods have been shown to give virtually the same results for recurrence intervals greater than 10 years (Langbein, 1949). Owing to the fact that most designers are interested in flood magnitudes with recurrence intervals of 10 years or more, the choice of series is of little practical importance. How ever, because of its relative simplicity, theoretical soundness (Chow, 1950), and availability of the data, the annual flood series was used for this report.

After selecting the type of flood series, it is necessary to decide on one of the several methods available for analyzing the flood magni tude-frequency relation. In the past the Geological Survey has used a method described by Dalrymple (1960) and now widely known as the index-flood method. However, as a part of the continual appraisal of methodology, another method was investigated and described by Benson (1962 and 1964). This method based on the correlation of flood magnitudes with significant hydrologic variables of the basin has been shown by Gruff and Rantz (1965) to be an improvement over the index-flood method, and consequently was used to define the flood magnitude-frequency relations presented in this report.

SELECTION OF GAGING-STATION RECORDS

The U.S. Geological Survey (1959, 1960, and 1964) compilation reports contain streamflow data collected by the Survey prior to September 30,1960 for all gaging stations in the Part 11 area. These reports were used to ensure that all available streamflow records were considered for inclusion in this report. Flood-peak data at miscella neous sites and at gaging stations are included in the tables of this report. However, only those stations with at least 10 years of record prior to the 1964 water year were considered for use in the flood- frequency analysis.

FLOOD-FREQUENCY ANALYSIS 5

There are several reasons why some of the gaging-station records that were considered could not be used in the analysis. Obviously, those that contain annual peak discharges seriously affected by arti ficial storage or diversion could not be used. However, where pos sible, diversion and flow in the stream were combined to provide a usable record of flood peaks.

Criteria for deciding when a station with at least 10 years of streamflow record was not suitable for use in the flood-frequency analysis are listed below.1. Ten annual momentary maximum discharges not available. Sta

tion records with 10 years of streamflow data do not always con tain annual peaks for all 10 years. Also, some of the older records contain daily maximum discharges rather than momentary maximums, and unless the daily figures could be adjusted to give reliable figures of momentary maximum discharges they were not used.

2. Less than 25-percent difference between drainage areas of adjacent stations on the same stream, the percentage difference being based on the size of the smaller drainage area. Only the sta tion with the longer record was used unless there was a period of nonoverlapping record. If a nonoverlapping period existed, the shorter. record was combined with the longer record by a ratio based on the size of the drainage areas.

3. More than 4.5 million cubic feet (103 acre-feet) of usable storage per square mile (Benson, 1962, p. 8). If record was available for at least 10 years prior to the construction of reservoirs that caused the criterion to be exceeded, the record prior to that time was used.

4. Some special indication of excessive diversion or regulation, even though not exceeding the usable storage criterion. A situation of this kind may arise where the gage is directly below a large reservoir.

5. Drainage areas smaller than 10 square miles. Only a few records are available on streams in this category, and most of them are grouped in one part of the study area. A project is presently (1965) underway to obtain data needed to define flood magnitude-frequency relations throughout California for small streams.

After the above criteria were met, records from 138 gaging stations remained for use in the flood-frequency analysis for the area covered by this report. The location of gaging stations not excessively reg ulated by storage or diversion and with 5 or more years of record prior to the 1964 water year is shown in plate 1. The 138 gaging sta-

tions used in the flood-frequency analysis are shown by solid circles, and those tabulated but not used are shown by open circles.

FLOOD FREQUENCY AT A GAGING STATION

Many of the gaging-station records used in this study were short- time samples, but in order to obtain reasonable areal coverage it was necessary that they be used. Whenever possible, the time base of the short-term stations was extended by graphically correlating the avail able annual peak discharges with peak discharges from one or more nearby long-term stations. The correlation, providing it appeared reasonable, was then used to estimate annual peaks for the years with out record at the short-term station.

When the record of annual peaks for a station was ready for analysis, each peak was assigned an order number according to its magnitude, starting with the largest as number 1. Next, the plotting position or recurrence interval, T, for each of the peaks was computed by means of the formula

T_n+l

where n=the number of years of record and m=the relative magnitude (order number) of the event.

The recurrence intervals were adjusted, where appropriate, on the basis of historical or qualitative information. For example, several stations in northwestern California have 34 years of record (1932-65), and the 1965 and 1956 peaks are greatest and second greatest, respec tively, during the period of record. Without considering historical information prior to 1932, the recurrence intervals for these two floods would be 35 and 17.5 years, respectively. However, in 1862 a flood estimated to be about equal in magnitude to the 1956 flood occurred, and local records reaching back to 1853 indicate that the peaks of 1862 and 1956 were exceeded only by the 1965 peak. Therefore, the 1965 peak has an order of magnitude of 1 in at least 112 years, giving it a recur rence interval of 113 years instead of the 35 years originally computed. Furthermore, the two peak discharges that occurred in 1862 and 1956 have orders of magnitude of 2 and 3 in 112 years, giving them recur rence intervals of 56.5 and 37.7 years, respectively. The recurrence intervals for other peaks during the period of record were not adjusted. All recorded peaks were then plotted at their appropriate recurrence intervals on extreme-value probability paper (Powell, 1943), and a straight line or gentle curve of best fit was drawn by eye. Estimated peaks were not plotted; their only purpose was to adjust the time base (order number) of the recorded peaks. Because the computed recur rence intervals of the larger (less frequent) floods are not as reliable as


those of the smaller (more frequent) floods, the larger floods tend to scatter more than the smaller floods when plotted on extreme-value probability paper.

Peak-discharge values were selected from each frequency curve at recurrence intervals of 1.2, 2.33, 5,10, 25, and 50 years. Flood mag nitudes for the four shorter recurrence intervals were available for all sites. However, because of the limitations on using peak-discharge figures obtained by correlation, the magnitudes for the 25- and 50-year floods were not available at all sites. The table below lists the number of flood peaks available for analysis for each of the six recurrence in tervals. The flood peaks are the dependent variables that were cor related with pertinent hydrologic characteristics.

HYDROLOGIC CHARACTERISTICS

The rate of runoff from a basin is controlled by its many hydrologic characteristics. To describe the relation between peak discharge and the characteristics, it is first necessary to determine which of the hydrologic characteristics are significantly related to flood peaks and can also be evaluated numerically. Selection of the hydrologic characteristics used in this study was made on the basis of studies by others in this and other areas (for example, Benson, 1962), as well as from first-hand knowledge of the area. The hydrologic characteristics considered in this analysis can be separated into three groups: topography, climate, and runoff.

TOPOGRAPHY

Six topographic characteristics were considered in the analysis. They are drainage area, main-channel length, an index of main-chan nel slope, an index of basin altitude (above mean sea level), percentage of drainage area above an altitude of 5,000 feet, and percentage of drainage area covered by lakes and ponds. Geological Survey topo graphic maps of the 7.5- and 15-minute series were used in determining the various topographic characteristics.

The drainage area (A ) is the area of the drainage basin, in square miles, measured in a horizontal plane. It is probably the most im portant of these characteristics. The drainage area for the stations used in the analysis ranges from 10 to 4,157 square miles.


The main-channel length (L) used in the analysis is the length, in miles, of the longest continuous stream channel from the gaging station to the drainage divide. The main-channel length for the stations used in this analysis ranges from 6.1 to 183 miles.

To determine the main-channel slope index ($), points at 10 and 85 percent of the total channel length upstream from the gaging station were located, and the altitude at these points was determined. The channel slope, in feet per mile, was computed as the difference in alti tude divided by the distance between the two points. The slope index for the stations used in the analysis ranges from 8.7 to 810 feet per mile.

The basin-altitude index (E] used in the analysis is the average of the altitudes of the two points 10 and 85 percent of the distance along the main channel upstream from the gaging station. It is expressed in thousands of feet. The altitude index for the stations used in the analysis ranges from 0.36 to 5.97. The altitude index is a substitute for the more commonly used mean altitude of the basin. The altitude index was used because a high degree of correlation was found to exist between the altitude index and the mean altitude of the basin and be cause the altitude index is much easier to compute.

The percentage of the drainage basin above an altitude of 5,000 feet (A2 ) was determined by placing a grid over a contour map of the entire drainage basin. The altitudes at the grid intersection points were then listed, and the percentage of the area above 5,000 feet was determined as the percentage of the listed altitudes that were above 5,000 feet. The values for the stations used in the analysis range from 0 to 86 percent.

The percentage of the drainage area covered by lakes and ponds (La) , both natural and manmade, was determined by measuring the area of lakes and ponds within the basin and expressing it as a per centage of the drainage area of the basin. The percentage of the area covered by lakes and ponds for the stations used in the analysis ranges from 0 to 2.8 percent.

CLIMATE

Two climatic characteristics were considered for this analysis mean annual precipitation and rainfall intensity. The mean annual precipitation (P) is the long-term average annual precipitation over the entire basin, in inches. A map with isohyetals showing mean annual precipitation was used to determine the basinwide average of mean annual precipitation for each basin. The map is shown in plate 2. The mean annual precipitation for the basins used in this analysis ranges from 15 to 82 inches.

The rainfall intensity (/) used for the analysis is the 24-hour rain fall, in inches, with a recurrence interval of 25 years. This value was


determined for each basin from isohyetals presented by the U.S. Weather Bureau (1961). The rainfall intensity for the basins used in the analysis ranges from 3.7 to 15 inches.

RUNOFF

The mean annual runoff (ft) , in inches, was the only runoff char acteristic considered. A base period of 30 years (1934-63) was used. Many stations did not have discharge records for the entire base period, and such gaps in the record were filled by correlations with records for nearby stations. The mean annual runoff for the stations used in the analysis ranges from 0.11 to 70.2 inches.

MULTIPLE-REGRESSION PROCEDURES

Multiple regression is defined as the relation between one dependent and two or more independent variables. Use of multiple-regression analysis in flood magnitude-frequency studies requires the develop ment of regression equations expressing flood magnitude as a function of hydrologic basin characteristics. Past experience has shown that the logarithms of peak discharges are linearly related to the logarithms of most hydrologic variables. The equations have the empirical form:

QT =aB^CcD^ ... (1) where

QT= discharge, corresponding to a recurrence interval of Tyears;

a regression constant; b,c,d= regression coefficients; and

B,C,D = hydrologic characteristics.

The regression equation is derived by' a least-square correlation of the T'-year discharges with the corresponding hydrologic characteristics for all sites used in the analysis. Statistical tests are made so that those variables having little or no significance can be eliminated from the equation.

Electronic computing techniques allow rapid computation of regres sion equations, whereas previously computation either by desk calculator or by graphical solution was required. Computation by desk calculator for more than two variables is a slow, tedious process, and graphical solutions become subjective and often inaccurate for more than three variables. Thus, when numerous variables are used, the multiple-regression analysis is practical only if an electronic computer is available.

The multiple-regression computer program used in this analysis provides a wealth of statistical information. Computer input data


consisted of the flood discharges (dependent variables) for each of the selected recurrence intervals of T years and the hydrologic character istics (independent variables) for the corresponding basins. Among other statistics, the output data consisted of simple correlation co efficients between each pair of variables, a multiple correlation coef ficient, the regression equation constant and coefficients, and the standard error of estimate of the logarithms of the dependent vari able. The computed values of the dependent variable, based on the derived regression equation, and the departure between the observed and computed values of the dependent variable for each station used in the analysis were also available. The observed values are those T'-year floods which were used as input data for the computer.

The computer program used provided for the elimination of the least significant independent variable (hydrologic characteristic) after an equation was derived and recomputation of the data without this variable. This procedure was repeated until only one independent variable remained. This type of analysis made it possible to determine when no large improvement in the results was obtained by the use of additional hydrologic characteristics. The following table shows the amount of improvement indicated by the multiple-correlation co efficient and the standard error of estimate of the dependent variable. Improvement is indicated by the approach of the correlation coefficient and standard error to 1.0 and 0, respectively. It is evident from these data that the inclusion of other variables in addition to J., P, and E causes no significant improvement in the correlation coefficient or standard error.

REGIONAL ANALYSIS

Because of the lack of long-term records of natural flow for every stream, one must analyze the available data on a regional basis to derive a regression equation for estimating data for ungaged or short- record sites. For multiple-regression analysis, the regions used should be such that the available hydrologic characteristics will correlate reliably with T'-year flood peaks within the region.


As a preliminary analysis, the entire area designated Part 11 was used as one flood-frequency region. The results from this analysis were used to determine if the Part 11 area could be used as a single homogeneous flood-frequency region or whether it would be desirable to delineate smaller regions. Also, this analysis was used to eliminate hydrologic characteristics that were found to be insignificant. On the basis of the preliminary analysis, the physiographic regions de lineated by Fenneman (1931), and the major drainage divides, six flood-frequency regions were delineated. The area covered by this report contains two of these regions (pi. 1), each of which is described below. The remaining four regions are considered in a companion report, Water-Supply Paper 1686 (Young and Gruff, 1967).

SOUTH COAST REGION

The south coast region (A) includes streams in California that drain into the Pacific Ocean between Lower California (Mexico) on the south and San Francisco Bay on the north plus streams that drain from the west into the San Joaquin Eiver valley (pi. 1). The region has a subhumid climate. Snow occurs at high altitudes but remains on the ground for only short periods of time. The altitude within the region ranges from sea level along the coast to 11,485 feet atop San Gorgonio Mountain in southern California. Most of the floods in the region are caused by general winter frontal-type storms that produce heavy runoff from large areas. A few floods are caused by local summer thunderstorms. Floods in the region are generally flashy with peaks lasting a short time.

NORTH COAST REGION

The north coast reegion (B) includes streams that drain into the Pacific Ocean between San Francisco Bay on the south and the Klamath River basin on the north plus streams that drain from the west into the Sacramento River south of the Clear Creek basin (pi. 1). The climate of the region ranges from subhumid to humid, with marked wet and dry seasons. The altitude ranges from sea level to more than 8,000 feet. Floods within the region are also caused by winter frontal-type storms, which cover large areas. Peaks from these floods generally last a short time.

REGRESSION EQUATIONS

Standard multiple-regression techniques as described by Benson (1962 and 1964) were used in analyzing the available flood data. As a result, equations relating floods of selected frequencies to selected


hydrologic characteristics have been developed for each flood- frequency region.

Drainage area, altitude, and mean annual precipitation were used at all selected recurrence intervals from 1.2 to 50 years to derive regres sion equations for use in region A. The equations are:

(2) 33 =0.0778A0 - 66#-°-59P2 - 20 (3)

(4)(5)

#25 =21.4A°-63#-°-09P1 -05 (6)#50= i37A°-55#-°-02P0 - 72 (7)

Drainage area and mean annual precipitation were used to derive regression equations for recurrence intervals from 1.2 to 50 years for use in region B. The equations are :

(8)(9)

(10)(11)(12)(13)

Equations 2 to 13 are shown in nomograph form on figures 2 to 13. Use of the nomographs is described in the section "Illustrative problem."

A summary of the regression equations is shown in table 1. The number of stations used to define the equation, the values of the regression constant and coefficients, the multiple-correlation coefficient, and the standard error is shown for each equation.

The standard error of estimate, here referred to as standard error, is a measure of the departure of the computed flood magnitudes from those observed. The computed standard errors ranged from 51 to 161 percent for region A and from 24 to 35 percent for region B. The percentages are the average of the plus and minus percentages com puted from the standard errors in log units.

The coefficient of multiple correlation is determined by the ratio of the standard error of the estimated values to the standard deviation of the observed or original values of the dependent variable. It is a measure of the combined importance of the independent variables in explaining the variation in the dependent variable. A value of 1.0 would indicate a perfect correlation, whereas a value of 0 would indi cate no correlation. The computed coefficients ranged from 0.605 to 0.841 for region A and from 0.965 to 0.978 for region B.

PROCEDURE FOR ESTIMATING FLOOD FREQUENCY

The equations presented in this report should not be used individu ally to determine the flood discharge for any selected recurrence inter val. Instead, a flood magnitude-frequency relation should be developed by solving the equations for each flood level (recurrence intervals 1.2, 2.33 ... 50 years) and plotting each computed discharge as a function of its frequency on probability paper. Any probability paper with frequency expressed either as a recurrence interval, T7, or as probability of recurrence, p, where

p -7p

can be used. Because of the inherent scatter in the data used to de velop the equations, the plotted points may not lie on a smooth curve. A smooth curve, fitted by eye as closely as possible to the plotted points, should be drawn and used to represent the flood magnitude-frequency relation.

The general procedures in denning a flood-frequency relation for a site, gaged or ungaged, in the report area are:1. Determine the hydrologic region in which the site is located by

referring to plate 1.


2. Determine the significant hydrologic characteristics for the site: Aj E, and P if in region A, or A and P if in region B. A and E are determined from topographic maps, and P is determined from plate 2.

3. Solve the equations or nomographs, applicable to the region equa tions 2 to 7 if in region A and equations 8 to 13 if in region B.

4. Plot the computed flood discharges as a function of their frequen cies on probability paper.

5. Draw a smooth curve through the plotted points.

ILLUSTRATIVE PROBLEM

To illustrative the computation procedure, assume that one is inter ested in the annual peak discharge having a recurrence interval of 50 years at gaging station 11-1195. The method used to determine this discharge is outlined below:1. Determine the hydrologic region in which the site is located. It is

in region A.2. Determine the significant hydrologic characteristics for the site.

In this example J., E, and P are used, where J. = 13.1 square miles, #=1.34, and P=25 inches.

3. From the equations or nomographs for region A, the discharges for the several recurrence intervals are determined. The nomo graphs are used by drawing a series of straight lines as indicated by the key on the nomograph. Figure 2, the nomograph for the 1.2-year flood in region A, is used here to illustrate the pro cedure. The key given on figure 2 indicates that the first step is to draw a straight line between the A and E scales, intersecting these scales at the appropriate values for the basin under study. The second step, according to the key, is to draw a straight line intersecting the pivot line (1) and the P scale. This line is drawn to intersect the pivot line at the same point as the line from the first step and to intersect the P scale at the appropriate precipitation value. The intercept of this line on the #i. 2 scale is the discharge in cubic feet per second (cfs). In this way the various discharges were determined, as follows: #i. 2 = 60 cfs,#2.gg=422 cfs, #5 =1,040 cfs, #10 =1,790 cfs, #25 =3,130 cfs, and#5o=5,060 cfs.

4. Plot the discharges as a function of their recurrence interval, or probability of recurrence, and draw a smooth line through the points. Figure 14 shows the plot for this sample problem.

5. From figure 14 the discharge having a recurrence interval of 50 years is found to be 5,000 cfs.

FIGURE 14. Flood magnitude-frequency curve for stream-gaging station in illustrativeproblem.

The graph in figure 14 can also be used to determine the recurrence interval of any known .discharge within the limits of the data. For example, from figure 14 the recurrence interval of a flood peak of 2,500 cf s at the gaging station is found to be 16 years.

LIMITATIONS

In using the methods presented in this report for determining flood magnitude-frequency relations, there are some limitations that should be considered. The limitation of primary importance is that the equations or nomographs apply only to sites within the hydrologic regions for which they were derived. Also, the procedure is not ap plicable to sites where the usable storage within the basin exceeds 4.5 million cubic feet (103 acre-feet) per square mile or where the site is just downstream from a large reservoir, even though the storage limitation is not exceeded. Furthermore, the procedure should not be used for sites where the drainage area is less then 10 square miles.

The relations were derived on the basis of hydrologic characteristics whose range in magnitude lay within limits imposed by the available


data. The limits for region A are: drainage area 10 to 4,200 square miles, altitude index 1.32 to 6.0, and mean annual precipitation 14 to 51 inches. For region B the limits are: drainage area 18 to 3,200 square miles and mean annual precipitation 28 to 82 inches.

It is emphasized that the outlined procedures for defining flood- frequency relations are valid for sites for which the hydrologic char acteristics have values within the limits given above; use under any other conditions may lead to erroneous results. The methods pre sented should only be used for flood magnitude-frequency definition for recurrence intervals ranging between 1.2 and 50 years.

DISCUSSION OF RESULTS

Table 1 indicates that the small floods those that have a recur rence interval less than 5 years cannot be estimated as reliably as the large floods. The reason in part is that for small floods the runoff is often generated in only a part of the drainage basin. The large floods usually result from more general storms which cause runoff from most or all of the basin, and therefore more consistent results are obtained for the large floods.

The median of the ratios of observed to computed flood values at each site for the selected T'-year floods was used as an indication of the reliability of the regional analysis. As a final step, the median values were plotted on maps for each region and were found to be randomly distributed geographically above and below the value of 1.0. For most stations the variation was within a reasonable range, but for a few stations the median values departed greatly from 1.0. The extreme departures also were randomly distributed geographically above and below the value of 1.0.

For a few stations, flood-frequency relations computed by the re gional method will give results considerably different than would be obtained by a single station analysis. For some stations, the differ ence may be due to a record being too short to give true results when used in a single station analysis. For other stations, the difference may be due to failure to consider some pertinent variable that differs from that of other streams in the region. Furthermore, the variable may be such that it cannot now be readily expressed numerically; for example, the infiltration characteristics of the basin, which in this study were hopefully believed to have been accounted for in the delineation of regional boundaries.

As more gaging stations are installed in different areas where vary ing hydrologic characteristics will be sampled and as the period of record at existing gaging stations grows longer, more information

FLOOD RECORDS AT GAGING STATIONS AND MISCELLANEOUS SITES 29

will be available that will better define the flood magnitude-frequency relation. An example is the December 1964 flood. In some areas this flood was considerably greater than any flood previously recorded; this caused the magnitude-frequency relation for many stations to dif fer from the relation that would have been obtained had the analysis been made before the flood.

The hydrologic characteristics in the final equations represent the smallest number of easily definable hydrologic characteristics that to gether best define the peak flows. As it becomes possible to evaluate numerically more hydrologic characteristics (such as geology, soil type, and physiography), it may be possible to use some of these variables for further refinement of the analysis in this report.

FLOOD RECORDS AT GAGING STATIONS AND MISCELLANEOUS SITES

A summary of pertinent data relative to maximum known floods in the report area prior to October 1965 is contained in tables 2, 3, and 4: table 2 for gaging stations used in the analysis, table 3 for gaging sta tions having more than 5 years of record prior to October 1963 but not used in the analysis, and table 4 for miscellaneous sites and gaging stations having less than 5 years of record prior to October 1963. The stations are listed by their permanent network numbers. Those listed in tables 2 and 3 are shown on plate 1. The part number has been omitted from the number in all tables, it being understood that all of the stations are in Part 11. The miscellaneous (M) sites in table 4 have been numbered consecutively in a downstream order beginning with Ml.

Following the tables is a compilation of flood peaks for each of the stations listed in tables 2 and 3. All available annual maximum flood peaks are listed for each station and, in addition, all flood peaks above a selected base discharge are listed for those years for which the data were readily available. For stations where the flood flow is affected by regulation or diversion, or where records are inadequate to define secondary peaks, only the annual maximum flood data are presented.

Underlines in the tabular data have the following significance:1. A horizontal line in the water-year column indicates discontinuous

records.2. A line across the gage-height column indicates a change in gage

datum and thereby shows that the gage heights above and below the line are not comparable. No lines are used if gage heights have been adjusted to a common datum.

3. Lines across the date and discharge columns indicate a change in site of sufficient magnitude to affect the stage-discharge relation.


Accompanying each list of flood data are descriptive and historical data pertaining to the gage site. These data show the most recent gage location; the type and history of the gage; the drainage area above the gage; a description of how the stage-discharge relation was defined; and when available, the bankfull stage, historical flood data, and other miscellaneous information that might be of use to persons interested in flood magnitude and frequency.

Gage.--Nonrecordlng prior to Sept. 2, 1917; recording thereafter. Datum of gage Is 1,984.28 ft above mean sea level, datum of 1929.

Stage-discharge relation. Defined by current-meter measurements below 1,500 cfs and extended above on basis of slope-area measurements at 24,000, 29,100, and 52,300 cfs.


Historical floods.--Peak discharge for flood of February 23, 1891, was 53,700 cfs, determined by slope-area measurement, from notes furnished by P. C. Pinkie, consulting engineer, Los Angeles.

Remarks. Peaks partly regulated by Big Bear Lake (capacity since 1912, 72,200 acre-ft) beginning in 1884. Peaks may be affected by diversion to Southern California Edison Co.'s canal below powerplant No. 2 since beginning of record. Only annual peaks are shown prior to Oct. 1, 1949. Base for partial-duration series, 150 cfs.

960. Haines Creek near Tujunga, Calif.

Location. Lat 34°15'50", long 118°16'15", in NE^NW^ sec.17, T.2 N., R.13 W., on right bank 0.5 mile upstream from mouth of canyon and 1.5 miles northeast of Tujunga.

Drainage area. 1.2 sq mi, approximately.

Gage. Recording prior to Sept. 30, 1961; crest-stage gage thereafter. Alti tude of gage is 2,430 ft (from topographic map).

Stage-discharge relation. Defined by current-meter measurements below 3.2 cfs and extended to 265 cfs on basis of velocity-area studies.


Historical data.--According to T. H. Olmstead in reports of the Board of Engi- neers for Flood Control to the Board of Supervisors, Los Angeles County, Calif., the flood of February 1914 had a maximum discharge of 4,620 cfs (computed by slope-area method).

Remarks.--City of Los Angeles diverts most of flow through two infiltration galleries upstream from station. Diversion probably has a large effect on all of the low peaks. Fire in 1919 denuded the entire basin. Only annual peaks are shown.

3885. Stony Creek near Hamilton City, Calif.

Location. Lat 39°43'25", long 122°02 I 47", In Capay Grant, on right bank 2.3 miles southwest of Hamilton City, 6 miles upstream from mouth, and 8 miles east of Orland, Glenn County.

Drainage area.--777 sq ml.

Gage. Recording. Prior to February 1946, at site 3 miles upstream at different oatum. Altitude of gage Is 150 ft (from topographic map).

Stage-discharge relation. Defined by current-meter measurements below 30,100 cfs prior to February 1946; below 30,000 cfs thereafter.


Historical data. According to a resident, T. J. Bennett, whose family has lived near the stream and 3 miles downstream from the gage since 1862, the flood of 1937 or of 1940 was the greatest of knowledge. Both the flood of 1937 and that of 1940 are believed to be somewhat higher than that of Mar. 1, 1941.

Remarks. Peaks regulated by East Park Reservoir (usable capacity, 50,620 acre- ft) beginning In 1910 and Stony Gorge-Reservoir (usable capacity, 50,100 acre- ft) beginning In 1928. Peaks may be affected by diversions for Irrigation of about 17,200 acres In Orland Project, Bureau of Reclamation. Only annual peaks are shown prior to Oct. 1, 1947. Base for partial-duration series, 2,000 cfs.

Location. Lat 39°23'25", long 123°06'55", in NE£ sec.30, T.18 N. , R.ll W., on left bank 500 ft downstream from Van Arsdale Dam and 5 miles north of town of Potter Valley.


Gage.--Recording prior to Mar. 3, 1927, and after Feb. 28, 1937; nonrecording Oct. 1, 1927, to Feb. 28, 1937. Prior to Mar. 3, 1927, at reservoir 800 ft upstream from Van Arsdale Dam at different datum. Altitude of gage is 1,400 ft (from topographic map).

Stage-discharge relation. Defined by current-meter measurements below 7,000 cfs prior to Mar. 3, 1927. Defined by current-meter measurements below 16,000 cfs and extended above on basis of computed flow over Van Arsdale Dam there after. Subject to changes owing to flashboards being added to dam crest at times.


Remarks. Water-stage-recorder graph and some discharge measurements furnished by Pacific Gas and Electric Co. Peaks regulated by Lake Pillsbury (usable capacity, 86,400 acre-ft) beginning in December 1921. Peaks are affected by diversion from Van Arsdale Reservoir through tunnel to Potter Valley power house (capacity, about 350 cfs) since at least 1910. Peaks for the years 1910-23, 1925-27 and 1936 are maximum observed. Only annual peaks are shown.
