Abstract

Discusses how construction of the Post Creek Cutoff has affected stream entrenchment in the Upper Cache River, Illinois. Construction of the cutoff involved diversion of the flow from the Upper to Lower Cache river, allowing it to flow directly into the Ohio river. Cutoff construction reduced the stream length, increased the stream slope and resulted in the formation of a gorge. Examines the environmental problems which occurred. Lowered water levels affected wetlands, drainage from ponds increased and further gullies formed laterally to the main channel. (C.J.U.)
