The 18,539 square miles of land and water are used in producing food, fiber, minerals, energy, recreation, wildlife, and other amenities. The depletion of the natural resource base, over time, and the conflicts among uses are major concerns of this study. This study was conducted in accordance with the Principles and Standards for Planning Water and Related Land Resources issued by the Water Resources Council, the President’s Water Quality Directives and the USDA Procedures for Planning Water and Related Land Resources, under Section 6 of PL 83-566.
