Big Muddy River
Encyclopedia
The Big Muddy River is a 156 miles (251.1 km) river in southern Illinois
. It joins the Mississippi River
south of Murphysboro
. The Big Muddy has been dammed near Benton
, forming Rend Lake
.
The Big Muddy has a mud bottom for most of its length.
The watershed of the Big Muddy was covered by the Illinoian Glacier
about 300,000 to 132,000 years before present. The Big Muddy basin formed after the retreat of that glacier.
The Big Muddy was not covered by the Wisconsin Glacier
, about 70,000 to 10,000 years before present. However, during the melting of that glacier, the level of the Mississippi River was much higher. Water backed up into the Big Muddy Basin, forming a lake much like the artificial Rend Lake but covering a larger area. The ancient lake silted in, forming a flat bottom. After the melting of the Wisconsinan glacier, the level of the Mississippi dropped, allowing the lake to drain. A new channel formed within the old lake bed. This channel meandered in the flat bottom of the Wisconsinan-era lake. This is why the Big Muddy tends to be so muddy.
The Big Muddy joins the Mississippi River in Jackson County
near the La Rue-Pine Hills Ecological Area. The Pine Hills are bluffs overlooking the Big Muddy as it flows through La Rue swamp. During the melting of the Wisconsinan glacier, the Mississippi River flood plain was filled with rushing meltwater in summer. During the winter the flow of meltwater was cut off, and the floodplain was a wide stretch of exposed mud. Winter winds created dust storms that covered Southern Illinois with "loess
", fine grained, wind born deposits. At the edge of the floodplain, dunes, called "loess hills", formed. The Pine Hills are loess hills standing several hundred feet above the floodplain.
Prior to the construction of Rend Lake, much of the ancient lake bed was swamp
: a forested area that was covered by water through most of the winter, and during wet summers. When the Big Muddy flooded, the water covered the flat bottom of the ancient lake bed for miles either direction from the meandering channel.
The upper reaches of the Big Muddy are near Dix, Illinois
. Here the outline of the Wisconsinan Era lake bed is evident in what were the northern reaches of the ancient lake, where the lake bed was only a few hundred feet wide. The steep Illinoian hills are suddenly truncated where they meet the flat bottom of the Wisconsinan Era lake bed. Here the tributaries of the Big Muddy are tiny, intermittent streams, meandering though these narrow valleys at the headwaters.
The Big Muddy basin contains a significant portion of the planet's coal
reserves. Most of this is hidden under its deep mud. At a few places the river has eroded the sides of hills, exposing coal deposits. The first coal mine in Illinois is believed to have been opened in 1810 on the banks of the Big Muddy in Jackson County
.
, the Little Muddy River
, Casey Creek, the Middle Fork of the Big Muddy and Crab Orchard Creek. The basin also includes Kinkaid Lake, Rend Lake, Crab Orchard Lake
, Devil's Kitchen Lake, Little Grassy Lake and Cedar Lake.
The northern limit of the watershed is north of Kell
, about 2 miles (3 km) into Marion County. This is on Casey Creek, which might be properly considered the main reach of the river.
