Lac Des Allemands, Louisiana, USA

Lake Locations:

USA - South - Louisiana - Greater New Orleans -

Lac Des Allemands is a natural 12,000-acre lake located about 25 miles west of New Orleans. The lake name is French for Lake of the Germans, referring to the early settlers who inhabited this area of Louisiana’s Mississippi Delta region. Lac Des Allemands is located mostly in Saint John the Baptist Parish and partly in Lafourche and Saint Charles Parishes. The community of Des Allemands lies southeast of the lake.

Lac Des Allemands is fed by numerous bayous in the Barataria Basin surrounding the lake, including Grand Bayou and Bayou Chevreuil. The Basin is criss-crossed by bayous, access canals, drainage canals, and navigation channels, including the Intracoastal Waterway and the Barataria Waterway. Most of the Basin is at sea level. Lac Des Allemands is a shallow lake, with a maximum depth of 10 feet and an average depth of five feet. It measures about 5.5 miles long and 6.5 miles wide. Lake waters flow southeast into the Bayou Des Allemands, then on to Lake Salvador and eventually to the Gulf of Mexico. Bayou Des Allemands provides a public boat ramp for access to Lac Des Allemands and Lake Salvador.

The community of Des Allemands, which lies along the banks of Bayou Des Allemands, suffered considerable storm surge flooding from Lac Des Allemands and Lake Salvador during Hurricane Ike in September of 2008. The Bayou currently has no flood control structures (pumps, weirs, etc.). The U.S. Army Corps of Engineers, the Louisiana Department of Transportation and Development, and the Lafourche Basin Levee District conducted a feasibility study pertaining to a 57-mile long hurricane levee through Bayous Des Allemands, connecting to the Davis Pond Diversion Project. Davis Pond diverts Mississippi River freshwater into the upper portion of the Barataria Basin, but does not connect directly to Lac Des Allemands.

Lac Des Allemands provides an extremely fertile habitat for catfish, bass, crappie, and panfish. The maze of bayous, canals, and cypress swamps provides a habitat of stumps, brushtops, fallen tress, and grass mats needed to produce ample numbers of these species. In 1975, Governor Edwin Edwards declared Des Allemands the Catfish Capital of the World. Three species of catfish (flathead, channel, and blue) spawn in the lake from May through September. Anglers commonly catch blues and flatheads ranging from 30 to 60 pounds. A canal east of Lac Des Allemands produced a record-setting 6 pound mixed crappie. Fishing camps dot the lake’s shoreline. The community of Des Allemands hosts the Louisiana Catfish Festival every second weekend in July.

While visiting Lac Des Allemands, take some time to appreciate the flora and fauna of Louisiana’s Mississippi Delta. The cypress tree-lined bayous provide the habitat for diverse wildlife viewing: otters, raccoons, great blue herons, egrets, frogs, alligators, and even bald eagles. Swamp boats provide tours of the cypress-tupelo wetlands. The area can be enjoyed year round. Summer temperatures range from daytime highs in the 90’s to nighttime lows in the 70’s. Winter temperatures range from highs in the 60’s to lows in the 40’s.

The nearby Bonnet CarrÃf© Spillway, operated by the U.S. Army Corps of Engineers, has developed into a popular outdoor recreation area. The Spillway is a flood control structure in St. Charles Parish, designed to allow Mississippi River flood waters to flow into Lake Pontchartrain and the Gulf of Mexico, thereby passing New Orleans. Today, more than 250,000 visitors enjoy the Spillway’s diverse recreational opportunities: biking, boating, fishing, crawfishing, hiking, primitive campground provided by St. Charles Parish, horseback riding, hunting (deer, ducks and other waterfowl, rabbit, squirrel), ATV and motorcycle riding, picnicking, water sports, dog training (retriever dog field trials), wildlife viewing, and model airplane flying competitions. The Parish provides two boat launching ramps.

Although Lac Des Allemands lies in the serene wetlands west of New Orleans, it is just a short trip across the Mississippi River to “The Big Easy.” Recreational and cultural activities in the area include the Audubon Zoo, the New Orleans Botanical Garden, and the Jean Lafitte National Historic Park and Preserve. Area parks include Fontainebleau State Park, the Fort Pike State Historic Site, Fairview-Riverside State Park, Bayou-Segnette State Park, and St. Bernard State Park.

Trophic State | LakeLubbers

Trophic State measures the level of algae and nutrients in a lake.

An oligotrophic lake is very clear (blue in color) and does not support much plant or fish life. A hyper-oligotrophic lake is the clearest of all lakes, and is nearly devoid of plants and fish.

A mesotrophic lake is slightly green and supports a moderate degree of plant and fish life. A lake's most desired trophic state is generally this mid-point - the mesotrophic state.

A eutrophic lake is somewhat murky and supports a large amount of plant and fish life. A hypereutrophic lake is clouded with algae, plant life, and fish life. A eutrophic or hyper-eutrophic lake can be difficult to navigate by boat - and is often an unpleasant place to swim.

The use of phosphorus-rich and nitrogen-rich fertilizer on lawns and golf courses surrounding a lake can cause it to become eutrophic or hypereutrophic.

Catchment or Drainage Area | LakeLubbers

This is the surrounding area that drains into a lake, including land, rivers and their tributaries. This is also known as the lake's "catchment basin".

Small lakes at the highest peaks of mountains have small drainage areas. The world's oceans have the largest drainage areas.

Water Residence Time | LakeLubbers

This is the estimated time that it takes for an amount of water equal to the entire volume of a lake to flow out of - or evaporate from - the lake.

Residence Time can be as short as a few days for fast-flowing small lakes, and can exceed 100 years for slow-flowing large lakes.

Completion Year | LakeLubbers

This is the year that a reservoir was first filled to the reservoir's normal elevation - or the year that a natural lake was first dammed. A large reservoir can take more than a year to fill after its dam is first closed.

The Grand Anicut in southern India is generally considered the world's oldest dam that still operates. Grand Anicut was constructed in the second century BC. It now impounds an irrigation network that includes roughly one million acres.

Water Volume | LakeLubbers

This is the estimated volume of water that a lake contains -- measured at the lake's normal elevation. By this measure, the world's largest freshwater lake is Siberia's Lake Baikal.

You can find many of the the world's largest lakes (by water volume) on LakeLubbers.

Water Volume can be measured in acre-feet, in cubic miles, or in cubic kilometers. One acre-foot is the amount of water needed to cover one acre (43,560 square feet) to a depth of one foot. One cubic mile equals 3,379,200 acre-feet. One cubic kilometer equals 810,713 acre-feet.

1 acre-foot is equal to 325,851 US gallons. Siberia's Lake Baikal contains about 6,276,367,740,000,000 gallons of freshwater - nearly 1 million gallons for every living person on earth.

The other - and more widely used - measure of a lake's size is the lake's surface acreage. By that measure, the world's largest freshwater lake is North America's Lake Superior.

Average Depth | LakeLubbers

This is the estimated average depth of the water in a lake -- measured at the lake's normal elevation. If the water volume and surface area of a lake are known, an estimate of the lake's average depth can be calculated:

Water volume ÷ Surface Area = Average Depth

Example: 1,000,000 acre-feet ÷ 20,000 acres = 50 feet average depth

Maximum Elevation | LakeLubbers

This is a lake's highest water level, measured by the lake's surface distance above sea level, that can occur during flooding. A lake's highest possible maximum elevation is usually the top of the lake's dam or spillway.

At lakes that include residential development, government regulations usually forbid the construction of homes below a lake's maximum elevation.

Minimum Elevation | LakeLubbers

This is a lake's lowest water level, measured by the lake's surface distance above sea level, that can be reasonably expected to occur. Low lake levels can occur due to deliberate seasonal draw downs for irrigation or impending snow melt, reduced water inflows, drought and evaporation, residential or commercial water demands, and hydropower generation.

Some lakes' minimum and maximum elevations are virtually the same. Lakes that generate hydropower may vary by several feet - according to power demand. Lakes whose primary purpose is to prevent flooding can seasonally vary by 100 feet or more.

When some lakes reach their minimum elevation, their boat ramps may not be long enough to permit boat access - and boats docked on shallow parts of the lake may end up on dry ground. In those cases, kayakers and shore-based anglers may be among the few happy recreational users of the lake.

Normal Elevation | LakeLubbers

This is a lake's normal water level, measured by the lake's surface distance above sea level. For a reservoir, this water level is also known as "full pond" or "full pool".

You can find many of the world's highest-elevated lakes on LakeLubbers. Lakes with the lowest elevations (known by LakeLubbers) are shown on the final page of that list.

Shoreline Length | LakeLubbers

This is the length of the exterior shoreline around a lake - measured at the lake's normal elevation. The shoreline length can be considerably shorter or longer when lake water levels are lower or higher than normal.

A lake with many coves has a much longer shoreline than a lake of similar surface area that is nearly circular in shape.

When known, the shoreline miles that we report in our statistics include only the lake's exterior shoreline, and exclude the shorelines of islands located within a lake's boundaries. In lakes with many islands, those islands' combined shorelines may exceed a lake's exterior shoreline.

You can find many of the world's longest-shoreline lakes on Lakelubbers.

Surface Area | LakeLubbers

This is the area (acreage, square kilometers, etc.) of the top surface area of a lake - measured at a lake's normal elevation. The surface area can be considerably smaller or larger when lake levels are lower or higher than normal. North America's Lake Superior is the world's largest freshwater lake by this measure.

The other measure of a lake's size is the lake's water volume. By that measure, the world's largest freshwater lake is Lake Baikal in Siberia.

You can find many of the world's largest lakes (acres) on Lakelubbers. There is no widely-accepted minimum surface area that defines a lake. What Lakelubbers describes as a lake, you might call a pond. The smallest lake that Lakelubbers currently includes is Hawaii's 2-acre Lake Waiau.

Water Level Control | LakeLubbers

This is the organization that controls water releases or outflows from the lake or reservoir. In the USA, this is often the US Army Corps of Engineers, a power company, a municipal water system, an irrigation district, or a paper manufacturing company. In the case of private or gated lakes, a homeowners' association may be the lake's controlling authority.

Many lakes cross borders, including North America's Great Lakes. The control of such lakes and their coveted freshwater may be amicably shared - or hotly disputed.

"Water wars" continue at many lakes as growing populations and crop irrigation needs compete for the freshwater that lakes contain.

Lake Type | LakeLubbers

There are 3 basic types of lakes that are currently included on LakeLubbers. 2 types may be dammed or not dammed, producing 5 classifications.

- A Reservoir is a man-made freshwater lake that is usually created by damming rivers.

- A Natural Freshwater Lake occurs naturally - often by glacial activity - and has a salinity of less than 30 parts per thousand. It may be dammed to produce electricity or for other reasons.

- A Natural Saltwater Lake occurs naturally and has a salinity of more than 30 parts per thousand (ppt). It may be dammed.

"Brackish" water may be categorized as freshwater or saltwater, depending on its salt content (salinity). Oligohaline water has less than 15 ppt of salt. Mesohaline water has 15-29 ppt. Polyhaline has 30-335 ppt.
