A Tale of Two Waters: the Missouri River,the Great Lakes and Management of Future Water Conflicts

Abstract

This paper analyzes recent developments regarding Missouri River management and water use, and the potential for an emerging inter-basin water dispute involving the Great Lakes. It is suggested that revisions to the U.S. Army Corps of Engineers' master manual for the Missouri River and increasing efforts to put Missouri River water to beneficial use in support of economic growth present the prospect of low water levels in the Mississippi River. With a history of looking to the Chicago diversion as a source for augmenting flows in the Mississippi River, it may yet again prove to be an irresistible temptation. The institutional capacity for managing such a water dispute seems surprisingly weak. The direction suggested is that mechanisms should be installed to ensure that Great Lakes water remains in its basin, consistent with watershed management practices. The recent efforts by the Great Lakes states and provinces represent an important development in this direction. It is further suggested that demand pressures in the Missouri River should be met through a similar commitment, potentially through a water sharing arrangement on the Missouri River, something which could be encouraged in part by ensuring stricter controls on the Chicago diversion.
