Louisiana Waterways
Louisiana has nearly 5000 miles of navigable waters to include rivers, bayous, creeks and canals.
Navigable -- water deep enough for safe travel by boat
Rivers
The State’s Most Important River
Messipi, Rio del Espiritu Santo, River Louis
Drainage basin covers more than 1,245,000 sq. miles
Empties into the Gulf of Mexico
The Mississippi River
The Mississippi River basin carries 375 billion gallons of water through LA each day.
Also brings 256 million tons of sediment down the river each year
The Red River
The Second largest river drainage system in the state
Formed from several smaller waterways
Ends in Avoyelles parish, flows into Atchafalaya and Mississippi Rivers
Other Rivers
The Pearl RiverThe Calcasieu RiverThe Sabine River
The Little RiverThe Tensas RiverThe Ouachita RiverThe Black River
The Atchafalaya River
Native American Choctaw words meaning “long river”

Which river flows directly into Lake Pontchartrain?

b. Amite River
c. Tangipahoa River

Lakes
Man-Made Lakes: Toledo Bend Reservior Lake D’Arbonne in Union Parish Lake Claiborne in Claiborne Parish Sibley Lake in Natchitoches Parish Lake Chicot in Evangeline Parish
Lakes
Natural Lakes Lake Pontchartrain 625 sq. miles but quite shallow Called a Tidal Lagoon, waters are Brackish Connects to the Gulf of Mexico
Lake Maurepas
Located west of Lake Pontchartrain The two are connected by Pass Manchac Tidal Lagoon Brackish
Northwest Louisiana
Caddo Lake Cross Lake Lake Bistineau
Other Lakes
Bayou D’Arbonne Lake Catahoula Lake Cocodrie Lake Calcasieu Lake Grand Lake
White Lake Lake Verret Lake Salvador Lake Borgne
Cutoff Lakes
Form when rivers seek shorter, straighter courses through flat terrain
The former bends or curves in the river become lakes when the river moves to a straighter route
Cutoff Lakes
When the Red River shifted its course away from the town of Natchitoches, it left behind a thirty-nine mile long cutoff lake. This scenic attraction is called the Cane River Lake. It can be confusing to call it both a river and a lake, but in its history it has been both.
Cutoff Lakes
False River in Pointe Coupee Parish Lake Bruin in Tensas Parish Larto Lake in Catahoula Parish
Terms to know
Bayou: a waterway that ranges in size from short and shallow, to long and navigable.
The word bayou comes from the Choctaw native language and means “creek”.
The French settlers called bayous “the sleeping water” in reference to bayous that are slow moving.
Terms to know
Sediment: material that settles to the bottom of a liquid (lake/river).
When the Mississippi flooded the land each year as part of its natural cycle, the sediment helped to create the rich agricultural land along its banks.
Terms to know
Drainage Basin: an area of land that drains into tributaries and eventually into larger rivers
Tributaries: smaller rivers and streams that flow into larger bodies of water
Terms to know
Raft Lakes: lakes created when huge logjams blocked the flow of a river. A raft created by masses of logs, tree trunks, and other debris could literally block the flow of a river. The water would then overflow into nearby swamps, forming so-called raft lakes.
Examples Caddo Lake and Lake Bistineau
Terms to know
Marsh Lakes: Created behind low groups of ridges located in the marshlands that border Louisiana’s Gulf Coast. These ridges rise only slightly above the marsh, but they are dry enough to support the growth of live oak trees along their tops.
Marsh Lakes
Chenier's: French term meaning place of oaks
trap freshwater from the overflow of nearby rivers headed toward the gulf. The water collects behind the cheniers, creating marsh lakes.
Marsh Lakes
The water remains fresh because the cheniers block the incoming saltwater that flows into the marsh from the Gulf.
Examples: White Lake in Vermilion Parish, Grand Lake in Cameron Parish, and Calcasieu Lake in Calcasieu Parish
