Clear Creek is a southern Illinois watercourse that rises in Jackson County and Union County, and discharges into the Mississippi River in Alexander County. [1]
Clear Creek is neatly divided by the bluffs of the Mississippi into two sections: nearer its headwaters it is a relatively clean and swift-flowing hill river, and in its lower half, below the bluff, it has become a channelized ditch, the Clear Creek Ditch (coordinates: 37°23′30″N89°21′11″W / 37.391716°N 89.353143°W ). [2] Clear Creek rises in the uplands of the Shawnee Hills near Cobden, Illinois. In its upper reaches, Clear Creek is an unusually clean and undisturbed stream for Illinois, as its watershed includes two of the largest wilderness areas in Illinois, Bald Knob Wilderness and Clear Springs Wilderness. Another section of the creek's watershed is protected by the Trail of Tears State Forest, and most of the remainder of the watershed is protected by the non-wilderness parcels of Shawnee National Forest. [3]
West of Jonesboro, Illinois, Clear Creek descends from the Shawnee Hills into the bottomland of the Mississippi River. In historical times, the stream fed a ribbon-shaped wetland that ran southward and parallel to the Mississippi River for approximately 15 miles (24 km) before discharging into a former watercourse of the main river, the Picayune Chute, east of Cape Girardeau, Missouri. Part of this wetland has been conserved as the Union County State Fish and Wildlife Area, but during the 20th century most of it was extensively ditched and drained for mosquito abatement and to promote agriculture. Engineers dug a ditch that carries Clear Creek's drainage southward a further eight miles (13 km) and takes in further runoff from adjacent Shawnee Hills creeks. The creek/ditch currently discharges into the Mississippi close to Thebes, Illinois. [3]
Wolf River is a 105-mile-long (169 km) alluvial river in western Tennessee and northern Mississippi, whose confluence with the Mississippi River was the site of various Chickasaw, French, Spanish and American communities that eventually became Memphis, Tennessee. It is estimated to be about 12,000 years old, formed by Midwestern glacier runoff carving into the region's soft alluvial soil. It should not be confused with The Wolf River which flows primarily in Middle Tennessee and southern Kentucky. The Wolf River rises in the Holly Springs National Forest at Baker's Pond in Benton County, Mississippi, and flows northwest into Tennessee, before entering the Mississippi River north of downtown Memphis.
The Kaskaskia River is a tributary of the Mississippi River, approximately 325 miles (523 km) long, in central and southern Illinois in the United States. The second largest river system within Illinois, it drains a rural area of farms, as well as rolling hills along river bottoms of hardwood forests in its lower reaches. The lower reaches of the river have been canalized to allow barge traffic.
The Shawnee Hills is a region of southern Illinois that rests mainly in an east-west arc roughly following the outline of the southern end of the Illinois Basin. Whereas Mississippian and Pennsylvania Age rock layers are deep beneath the soil surface in central Illinois, these strata pierce the surface in southern Illinois. The Shawnee Hills are surface expressions of the more weather-resistant limestone and sandstone layers. This formation is due in part to the last glaciation of the Ice Age not reaching this far south.
The Shawnee National Forest is a United States National Forest located in the Ozark and Shawnee Hills of Southern Illinois, United States. Administered by the U.S.D.A. Forest Service, it consists of approximately 280,000 acres (1,100 km²) of federally managed lands. In descending order of land area it is located in parts of Pope, Jackson, Union, Hardin, Alexander, Saline, Gallatin, Johnson, and Massac counties. Forest headquarters are located in Harrisburg, Illinois. There are local ranger district offices in Jonesboro and Vienna. The Shawnee National Forest is also the single largest publicly owned body of land in the state of Illinois. It is considered part of Southern Illinois, and is south of the St. Louis, Missouri and Metro-East areas, in Area code 618. Portions of it are in the far south area of Illinois known as Little Egypt. Cities in or near the area are Carbondale, Illinois, Marion, Illinois, and Cairo, Illinois.
The Big Muddy River is a 156-mile-long (251 km) river in southern Illinois. It joins the Mississippi River just south of Grand Tower. The Big Muddy has been dammed near Benton, forming Rend Lake.
Mountain Fork, also known as the Mountain Fork of the Little River, is a 98-mile-long (158 km) tributary of the Little River in western Arkansas and southeastern Oklahoma in the United States. Via the Little and Red rivers, it is part of the watershed of the Mississippi River.
The Saline River is a tributary of the Ohio River, approximately 27 miles (43 km) long, in the Southern Illinois region of the U.S. state of Illinois. The river drains a large section of southeast Illinois, with a drainage basin of 1,762 square miles (4,564 km2). The major tributaries include the South Fork, Middle Fork and North Fork, all lying within the Saline Valley. The once meandering swampy river was important among Native Americans and early settlers as a source of salt from numerous salt springs where it was commercially extracted in the early 19th century.
