This appendix presents the proposed comprehensive plan of development for the basin and describes and analyzes the planning processes leading to its development. The plan is designed to meet existing and anticipated water and associated land resource needs of the Red River Basin below Denison Dam for the next 100 years. These needs include: water supply for municipal, industrial and irrigation uses; water quality control; flood control; drainage; watershed protection and flood prevention; navigation; bank stabilization; hydroelectric power, grazing and cropland improvements; forestry production; outdoor recreation; fish and wildlife enhancement; regional development; environmental preservation; and control of disease-bearing vectors. The plan is developed in sufficient detail to be used as a basis for obtaining Congressional authorization for projects required within the next 10-15 years, as well as providing a framework for future development of the basin's resources. The formulation process recognized that increasing the national wealth, encouraging economic development in the Red River Basin, and preserving and enhancing the physical environment of the basin are all appropriate objectives of water resource development. In developing the plan, alternative projects and plans to satisfy the various needs of the basin were assembled. These alternative projects were then evaluated and compared to isolate those that would contribute most to the basin's economy. The basic yardstick utilized in comparing alternatives was the national efficiency objective. The use of this yardstick was, however, tempered by consideration of the less tangible economic and social impacts of the alternative projects.
