STAFF REPORT

Decrease in Aquifer Levels Analysis

Residency and Snowmaking Activities Background:

District staff monitors and records water aquifer levels and water production for all wells on a daily,

monthly, and annual basis, in order to maintain and preserve the communities’ water supply. Aquifer

levels for Well 2 and Well 4 are recorded daily, while Well 3 and Well 5 currently lack telemetry devices

that would allow for daily data gathering. Well 2, a shallow well, that is subject to highly seasonal

variation, is not generally considered a useful source for the overall state of the communities’ aquifer

health and water supply. Therefore, the Well 4 aquifer data, is the primary source for determining water

supply and aquifer integrity.

District staff began to notice a significant decrease in Well 4 aquifer levels beginning in mid-July

continuing to the present recoded month. Data analysis was initiated to determine possible causes for this

decrease.

The District entered into an Agreement with Heavenly Valley, Limited Partnership (HVLP), on October

8th, 2015 to provide water and electric services for the purpose of snowmaking operations at the Timber

Creek Lodge area. It was agreed that the District would provide water services under the condition that

community water supply and aquifer levels were not adversely impacted. District staff gathers and

records water usage while snowmaking operations are underway and compares that data to aquifer levels

to determine impact on water operations. Generally, snowmaking operations have not exceeded the

100,000 gallon per day limit established by the agreement. Snowmaking activities for 2020 began on

November 6th, with an average consumption of 48,390 gallons per day over an 8-day period. This rate of

consumption would generally not create an adverse impact on District water supplies under normal

circumstances.

2019 38,434

2020 48,390*

*7-days data

Findings:

Since the decrease in aquifer levels began to take place prior to snowmaking operations, and the water

consumed by those operations is not significant to this date, it has been determined that those operations

have not contributed to the overall decrease in aquifer levels. 2020 aquifer levels, along with the 5-year

average for aquifer levels are illustrated in Table 1 of this report. The decrease in aquifer levels began in

mid-July. Table 2 depicts water production for each year over a 5-year period. It should be noted that

4

November 13, 2020

water production levels increased from 2019 to 2020 beginning in May. Total yearly water production is

illustrated in Table 3. While 2020 data is incomplete, it seems probable that 2020 will show an increase

in water production over 2019 totals.

Table 4 compares the aquifer levels between 2019 and 2020 and indicates a decrease in levels beginning

in August of 2020. During the summer of 2020, Production for Wells 4 and 5 were increased and

decreased for Well 2 due to a variety of mechanical issues. This contributed to the decrease in Well 4

aquifer levels. Additionally, it is believed that this may have led to an increase in Manganese and Iron

levels in Wells 4 and 5 which will require attention in the near future as Manganese has surpassed the

Secondary Maximum Contaminant Level for that constituent.

Additionally, staff has recommended that development of Well 6 be undertaken during the last two

budget cycles. The development of this critical, additional groundwater source has not been a part of the

Capital Improvement Budget at this time.

Table 5 contains the most compelling data for the purposes of this report and analysis. This table

compares occupancy of residents by water usage between 2019 and 2020 and shows the percent increase

or decrease in residency by month. A significant increase in residency rates began in May of 2020 which

is unprecedented for this community. It is generally accepted that large number of homeowners have

sheltered in Kirkwood during the Covid-19 pandemic beginning in May of 2020 continuing to the present

month of recorded data.

The most significant contributing factors to the decrease in aquifer levels are the increased occupancy of

residents during the Covid-19 pandemic, increased use of Wells 4 and 5 due to mechanical issues at Well

2, and lack of an additional water well.

Recommendation:

It is anticipated that additional water supplies for snowmaking will be available from Caples Lake next

week pending approval from State Water Resource Control Board. This will alleviate much of the

demand from District water sources. Therefore, I recommend that the water supply for Timber Creek

snowmaking efforts be suspended until the Well 4 aquifer returns to 140 feet. Further, I recommend that

Vail snowmaking operations contact the District daily for approval to conduct such activities. Approval

should be granted only if aquifer levels are at or exceed 140 feet.

It is also strongly recommended that the District endeavor to develop Well 6 for an additional water

source to alleviate demand on Wells 4 and 5. This will also lower Manganese and Iron levels in the

distribution system.
