Show PART VI FRAMEWORK PLAN AND ALTERNATIVES The installation costs of salinity control features for the combined Upper and Lower Colorado River Basins are estimated to be $2^1 million. The estimated annual operation and maintenance cost after completion of construction is $7>59O?OOO. Salinity control costs are not included in the cost tables. The program costs for associated development include specific costs for on-farm irrigation systems; thermal-electric plants and the transmis- sion lines therefrom; nonwater-based recreation; and fish and wildlife for improving hunting, other than waterfowl hunting, by managing and im- proving the habitats, acquiring and improving access to hunting lands, and species management. Adequacy of Framework Plan Land and water supply is generally not a limiting factor in the framework plan in meeting the regionally interpreted OBERS level of de- velopment. Agricultural sector The framework plan will meet regionally interpreted OBERS production goals from irrigated lands by developing new land and water and increas- ing production on the present lands. Although 100,000 acres of dry crop- land are shifted to other uses, the remainder, using proper management, is adequate to meet requirements. Although 7.1 million acres of grazing land will be retired or shifted to other uses, forage production will "be adequate to support the livestock industry and wildlife requirements. Timber production requirements will be met only if the accelerated pro- grams are put into effect. Watershed management and flood control Watershed management treatment programs will reduce the man-created erosion and sediment production and associated damage by k-0 to 60 percent. The remaining damages are largely geologic in nature and not economically susceptible to treatment. Some natural problems may be susceptible to treatment. Upstream flood and sediment damage will be reduced 30 to 50 percent. Multipurpose reservoirs built on the stream system will trap sediment and reduce sediment contribution to many downstream areas. The plan is in agreement with existing protection and development programs. The framework plan would reduce average annual flood damages in the amounts shown in the tabulation on the following page. Flood damage would be reduced to a reasonable level by the structural and nonstruc- tural measures of the plan. However, a large portion of the estimated. future flood damage is located in the sparsely populated upstream non-ur- ban areas where it is not feasible to provide all necessary measures to 75 |
