Abstract: In the early 1970’s, the Corps of Engineers realigned the Cache River from the mouth of Bayou DeView to its confluence with the White River near Clarendon Arkansas. This channelization isolated portions of the historic Cache River because plugs were placed in the upstream openings of at least six meanders, thereby changing them from flowing river into standing backwater. This portion of the river lies partially within the Cache River National Wildlife Refuge, an internationally recognized wetland of importance, and a major portion of the Mississippi Flyway. The purpose of this study is to determine the feasibility of restoring riverine conditions to isolated meanders located within the lower reach of the Cache River. The return of riverine flow to the historic meanders would restore aquatic habitat within the area. The scope of the study consists of analyzing alternatives to restore flows in up to six meanders cut off by the original flood control project. Various alternatives were considered, and a recommended plan was determined. In compliance with federal policy, a national ecosystem restoration plan was identified that would restore all six cut-off meanders. However, due to funding issues, the recommended plan is a locally preferred plan that restores the upper three meanders.
