Lake Washington, Minnesota, USA

Lake Locations:

USA - Midwest - Minnesota - Southern -

Lake Washington is a uniquely-shaped body of water situated just northeast of the Mankato Regional Airport, in Minnesota’s Southern tourism region. While most of the lake’s 1,487 acres fall within Le Sueur County, a small portion is considered a part of Blue Earth County. Featuring a maximum depth of 51 feet and a shoreline length of 13 miles, Lake Washington is ideal for water sports like swimming, boating and water skiing. Tubing, windsurfing and wake boarding are also popular pastimes.

Anglers look forward to exciting Lake Washington ice fishing during the winter, and adrenaline junkies will jump at the opportunity for sky diving nearby. Special events like snowmobile radar runs, fishing contests, and softball tournaments on ice are held at the lake, depending upon the time of year. A boys and girls club known as Camp Patterson has been providing wholesome recreational opportunities for young lake lovers since 1923.

Fishing is successful around Lake Washington’s buoys, particularly in Baker’s Bay, Squirrels Point, and Crystal Bay. First, Second and Third Points are other recommended places to drop anchor. These inviting waters are teeming with freshwater drum, black crappie, and white crappie; and you can reasonably expect to hook a few decent bluegills and walleye. Northern pike are known to reach lengths of up to 39 inches, while largemouth bass normally hit 11 inches. Lucky anglers might walk away with one of nineteen other species present in these waters, like bigmouth buffalo, white sucker, yellow bullhead and bowfin.

Facilities at Lake Washington include DNR boat launches, picnic areas and a restaurant with lakeside patio. In response to its many draws, nearby real estate properties and vacation rentals around the lake are available and in great demand.

Lake Washington features only 450 residences, with over 80% of homeowners living there year-round. Countless visitors spend their holidays on Lake Washington’s peaceful banks, and even more come from Mankato and St. Peter for picnics and day outings.

Minneopa State Park is a terrific jaunt from Lake Washington, boasting 4.5 miles of hiking and 4 miles of cross-country skiing trails. Dog sledding (only at Seppman Mill) and snowshoeing are allowed anywhere in the park, along non-designated ski trails only. Camping is available year round, with amenities like showers, flush toilets and a seasonal dump station. Other attractions include picnic shelters, volleyball and horseshoe courts and a nearby golf course. Bird watching yields fantastic chances to spot Louisiana water thrush, loggerhead shrikes, and elusive Bell’s vireo. Numerous species of Kentucky warbler, flycatcher, and sparrow are also prevalent, particularly around the magnificent Minneopa Creek waterfalls.

Just 10 miles south of Lake Washington, the city of Mankato offers a wide range of urban entertainment like bowling alleys, mini-golf courses and ski areas. Two local theaters and the Blue Earth County Heritage Center are the area’s main cultural attractions. Every year during the month of July, the unforgettable North Mankato Fun Days are held. This carnival features food tents, bingo, mini dance clubs and even a parade.

Bring your friends and family to Lake Washington’s irresistible shores for a picnic or a barbecue, and you are sure to fall in love with the area’s overwhelming beauty and astounding simplicity. Clean, shimmering waters make it the ideal place for summer swimming and year-round relaxation. Come bathe yourself in Lake Washington’s alluring water, and you’ll wonder how you ever lived without it.

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.

Maximum Depth | LakeLubbers

This is the estimated greatest depth of the water in a lake -- measured at the lake's normal elevation. The world's deepest lake is Siberia's Lake Baikal; that lake's maximum depth is estimated at 5,314 feet.

You can find many of the the world's deepest lakes on LakeLubbers. If you select the last page of that list, you will find the (maximum depth of) the shallowest lakes in our database.

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.
