Main Report: Ouachita River Basin Study, Arkansas and Louisiana

Excerpts from the report: The study area includes the entire Ouachita River Basin within the Lower Mississippi Water Resource Region and a portion of the Red River Basin in Rapides and Avoyelles Parishes. This covers about 25,900 square miles in the southern half of Arkansas and the northeast quadrant of Louisiana. The Ouachita River originates in the Ouachita Mountains of west central Arkansas and outlets into the Black River in central Louisiana, which in turn empties into the Red River in Avoyelles Parish in east central Louisiana. The drainage area consists of approximately 3,500 square miles of the Ouachita Mountains in Arkansas; 15,000 square miles of hilly uplands in Arkansas and Louisiana; and 7,400 square miles of flat, alluvial areas in Arkansas and Louisiana. This study is intended to provide direction in future land and water resources development planning in the Ouachita River Basin by providing information on existing resources, resource limitations, future need and demands, and recommendations for alleviating problems, meeting needs, and the extent to which assistance can be provided under USDA programs. It would also indicate remaining needs and concerns that would require solutions under state and local programs.
