96 6. National Parks, Monuments, and Recreation Areas. There are twenty-one National Parks and Monuments located within the Lower Colorado River Basin.5 Local water supplies are used for recreation, stock and wildlife watering, various domestic uses, power and, occasionally, for irrigation.0 Because of the number of National Parks and Monuments and because of the relatively small amount of water used by them, detailed discussion of their water supply and uses is not set forth herein. 7. National Forests. There are eleven National Forests in the Lower Colorado River Basin.7 They were established for the following purposes: (1) the protection of watersheds and the maintenance of natural flow in streams below the sheds; (2) production of timber; (3) production of forage for domestic animals; (4) protection and propagation of wildlife; and (5) recreation for the general public. Water is used for recreation, domestic purposes, irrigation and stock watering.8 8. Bureau of Land Management. The Bureau of Land Management is the United States agency in charge of public lands. It has instituted livestock grazing and water spreading programs on public lands. The latter activity is designed to increase the production of forage and to prevent erosion. Flood flows in normally dry washes are diverted and applied as irrigation water to the range. The application of this water increases the growth of forage and prevents erosion by discouraging the concentration of cattle at watering holes.9 "See U. S. Ex. 2800. 8Tr. 15840 (Dunn). 7See U. S.
