Lake Mattoon, Illinois, USA

Lake Locations:

USA - Midwest - Illinois - Central -

Surrounded by farmlands in the Central region of Illinois is Lake Mattoon. A quiet and tranquil retreat for many Illinoisans and out-of-towners, the lake is also a dynamic and lively location for the bustles of summer. Fishing tournaments, waterfowl hunting and sailboat races are some of the faster-paced events taking place at Lake Mattoon. But visitors just as equally enjoy viewing wildlife or a blissful picnic under hickory, oak and walnut trees that in the fall adorn the lake with vibrant beauty.

Popular for such a bounty of activity as boating, fishing, camping, sailing, and water skiing, Lake Mattoon lays 1,065 surface acres across three counties. Coles, Shelby and Cumberland counties all share a portion of this resourceful lake with almost three quarters of the lake in Shelby alone. Mattoon Lake occupies the Central region of Illinois; a region characterized by its historical marks and popular recreational amusements such as Abraham Lincoln’s Home, Tomb and Presidential Museum, the intriguing Amish Country and the Allerton Park and Retreat Center, considered a National Natural Landmark. Nearby, Lake Shelbyville is a nature wonderland. The lake and the Eagle Creek State Park on its shores offers hiking trails, camping, beaches, horseback riding, hunting and more. Lake Shelbyville is 11,000 acres and has 23,000 acres of surrounding land.

Anglers will be thrilled with Lake Mattoon’s abundance of bass, bluegill, catfish, crappie and striped bass. The average depth of the lake is not too deep, just 10 and a half feet. The Little Wabash River feeds into the lake and a little further away on the river is another artificial reservoir, Lake Paradise. The water level of Lake Mattoon is maintained by its dam, the construction of which was completed in 1957. Although the City of Mattoon owns the lake, a little more than half of the shoreline and 349 acres of lake property, visitors and lake residents alike have adopted this playground as their very own. What is more, the lake serves as a source of water supply to the cities of Mattoon and Neoga.

Lake Mattoon is a wonderful place to be in the summer time. The thick of trees encircling the 55.5 mile shoreline are a refreshing green. The Lake Mattoon Public Beach is alive with the movements of all shapes and sizes. The pavilion is a gathering place for family reunions and other special events. The second week of June is the Annual Y-Flyer Fleet 39 Regatta and July is the month of Bagel Fest. Summer is not the only season the matters though. Lake Mattoon is beautiful in the winter too, with the bright snow layered on the ice and the bare trees standing like naked testaments. A day or two will not be sufficient time to fully experience all Lake Mattoon has to offer. Look for one of the vacation rentals available on the lake or in the area. Or feast your eyes on some samples of gorgeous real estate. Imagine having your own home on the lake with your front lawn touching the water. Become part of a thriving community and join the Friends of Lake Mattoon in their efforts to keep the lake beautiful.

Among the many things to do in the Mattoon area, the Douglas Hart Nature Center has hiking trails, a captivating bird observation area, interpretive exhibitions and guided walks. Golf courses provide another class of enjoyment and a visit to an apple orchard will get your lips smacking. Come with the children in tow and the intention to have an outstanding vacation. Or settle on the lake marvelling each day on such things as the sublime sun rise on the water and the joyous wonder of baby ducks as they swim in line behind their mother. You will love it at Lake Mattoon.

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.
