Subject(s):cache river

Abstract:The Cache River basin is located in the extreme southern part of Illinois, just north of the confluence of the Ohio and Mississippi Rivers, as shown in figure 1. The basin covers parts of the six southern Illinois counties of Union, Johnson, Alexander, Pulaski, Massac, and Pope. The total drainage area of the watershed is 737 square miles. Since the construction of the Post Creek Cutoff in 1915, the Cache River basin has been divided into two subwatersheds: the Upper Cache and Lower Cache River watersheds, as shown in figure 2. The Upper Cache River watershed consists of the eastern part of the Cache River basin with a drainage area of 368 square miles; it drains directly to the Ohio River at River Mile 957.8 through the Post Creek Cutoff. The Lower Cache River watershed consists of the western part of the Cache River basin with a drainage area of 358 square miles; it drains to the Mississippi River at River Mile 13.2 through the diversion channel at the downstream end of the river. Eleven square miles of the Lower Cache River watershed continue to drain into the Ohio River at River Mile 974.7 through the original channel.
