The problem area is made up of the White River Basin comprising 27,765 square miles.of which 10,622 are in the southern part of Missouri and 17,143 are in the northern and eastern parts of Arkansas. This area encompasses some 50 counties' in the two-State area and over 1,200,000 people. The projects located in the basin have a total storage capacity of 16,062,000 acre-feet of which 5,477,000 is for flood control, 3,349,000 is for power generation; 925,000 is for drawdown for power generation and water supply; and 6,311,000 is for recreation, fish and wildlife conservation and other purposes. There is a desire for increased emphasis in meeting the needs of the recreation industry by reducing the full fluctuations to the maximum extent possible. Enhancement of the downstream trout fishery by providing adequate cold water releases during the critical summer months and provision of a greater degree of flood protection. There is also a need for generation of more hydroelectric power due to the energy shortage, waste water management due to increased urbanization in adjacent cities and communities, and development of retirement communities in summer homes and for the preservation and enhance- ment of the environment. See Arkansas Map 2. 7. Little Rock Urban Study - Arkansas. The study area includes the Little Rock SMSA which is made up of Pulaski and Saline counties with a population, based on 1970 census, of 323,000. The area, based on 1975 figures, has over 390 industrial firms and employs over 28,000 people. The area needs are for additional water supply in Jacksonville, Sylvan Hills area of North Little Rock, and northern Pulaski County. In addition to this there is an urgent need for additional sewage treatment facilities particularly in the urban areas outside the city limits. The continued growth of urban areas has had an impact on the runoff characteristics of urban drainage basins and continued housing developments are being constructed in areas subject to frequent flooding. See Arkansas Map 3. The study will be integrated with existing comprehensive develop- ment plans prepared by local and state areas as well as federal interest representing the metropolitan area. Corps studies included in this coordinated effort are Fourche Creek and Dark Hollow. In addition to the usual type of Urban Study, the wastewater portion of the Little Rock Study was expanded to meet E.P.A. guide- lines for a Section 208 Study; thus allowing a contract to be signed, enabling the technical portion of the 208 Study to be satisfied by it. 104
