An estimated average use per visitor day is 50 gallons. As the ultimate recreation use is reached, areas of Federally-owned land now in agriculture will be used to provide space for this recreation. This shifting of land use will result in less water consumption. Permanent residential use on lands leased under the Lower Colorado River Land Use Plan will be limited. Townsites not on reclamation withdrawn land will provide homes for the majority of the people providing services for the visitors to the area and will also provide homes for those people who wish to live in an area where the recreation facilities on the River will be available without extensive travel from their homes. Except for one proposed townsite near Cross Roads, California, the proposed residential areas will be considerable distance from the River and will have to rely on ground water for domestic water supply in their early stages of development. When the population of these residential areas reach their ultimate size, it may be necessary for these proposed municipalities to install water systems to supplement this ground water source. 5Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,430,208 byte
