Show SUMMARY (Continued) quantities and costs in Tables 8 through 11. These structural measures and specific land treatments in conjunction with management will correct most of the existing problems that can be treated and provide increased protection as an integral part of projected future production activity. Some of the more important treatment needs in the Framework Plan to reduce erosion, flood arid sediment problems are: seeding 1.1 million acres; brush and weed control 2.6 million acres; sheet erosion control 333,000 acres; watershed tillage 316,000 acres; stabilization 208,000 acres; watershed treatment 273,000 acres; 4,400 miles of gully control; and 78,000 water control structures such as detention dams, check and drop structures, diversion dams, sediment and debris basins. Improved management systems will be applied to all grazed areas, 5.8 million acres of unsuitable land will be retired, and overgrazing of 8 million acres will be eliminated to assist the land treatment program in improving watershed condition. The Framework Plan developed herein is designed to meet regionally interpreted OBERS requirements which are based on the Office of Business Economics - Economic Research Service (OBERS) projections modified to fit the local conditions in the region. This plan is described in detail in this report, then is followed by alternative plans that reflect emphasis on different uses for available water supplies and resources. The alternative State plans are identified as: 1. States' alternative to the Framework Plan (6.5 million acre-feet level of development). 2. States' alternative at the 8.16 million acre-feet level of develop- ment. 3. States' alternative for water supply physically available at site in the region. Other planning alternatives considered are: 1. Going Program as of the 1964-69 period. 2. OBERS as published. 3. Alternative without additional watershed land treatment or flood protection. Watershed treatment programs needed to correct the treatable existing problems will be the same for all alternatives, and will be accomplished if funding is available. With greater intensification of use under alternatives, additional protection will be needed to prevent erosion, sediment, flood and fire damage. This increased protection will be an integral part of the increased production activity. Approximately ii |
