The Bureau of Land Management has developed a water source inventory to identify and characterize water uses and respective sources on the public lands. Saline springs are identified through the program. Control of saline springs is analyzed through BLM's planning process with major sources being brought to Reclamation's attention. u.s. Department of Agriculture Public Law 98-569 provides a separate authority for implementation of USDA Colo- rado River Salinity Control projects. The initial funds for implementation were appropriated in FY87. Public Law 98-569 authorized the Secretary of Agriculture to: (1) identify salt source areas and develop project plans for salinity control; (2) provide financial and technical assistance to land users to plan, install, and maintain salinity reduction practices including voluntary replacement of incidental fish and wildlife values foregone; (3) conduct research, demonstration, and education activities; and (4) monitor and evaluate program effectiveness. To date, USDA implementation plans have been prepared for the Uinta Basin, Uinta Basin Expansion, Grand Valley, Lower Gunnison Basin, McElmo Creek, Mancos Valley, Virgin Valley, and Big Sandy River salinity control projects. A joint salinity control plan has been prepared by SCS and Reclamation for the Price-San Rafael area in Utah. Preliminary investigations are underway in the San Juan Basin of New Mexico. Current USDA implementation efforts are concentrated in the Grand Valley, Uinta Basin, Lower Gunnison Basin, Big Sandy River, and McElmo Creek Projects. The U.S. Department of Agriculture implementation schedule is controlled by annual appropriations for the Colorado River Salinity Control Program. Funding was allocated to the Grand Valley and Uinta Projects in 1987 and each year thereafter. In 1988, the first Colorado River Salinity Control funds were allocated to the Lower Gunnison Basin and Big Sandy River Projects, and in 1990, funds were allocated to the McElmo Creek Project. Other project implementation starts are scheduled to be phased in over a period of years as program funding levels increase. The imple- mentation schedule for USDA projects is based upon projected salt-load reduction needs, cost-effectiveness analysis, the probability of Federal funding, and the Basin Fund repayment capability. Public Law 98-569 directs the Secretary of Agriculture to carry out a monitoring and evaluation program to evaluate the effectiveness of USDA's Colorado River Salinity Control Program. In 1987, the Technical Policy Coordinating Committee of SCS and Reclamation published the Monitoring and Evaluation of Salinity Control Projects Interim Guide for the Colorado River Basin Salinity Control Program. In August 1991, SCS published the Framework Plan for Monitoring and Evaluating the Colorado River Salinity Control Program. This publication provides detailed instructions for all monitoring and evaluation (M&E) activities carried out by USDA. The three general purposes of the M&E effort are: (1) collect salinity control data; (2) evaluate the effect of salinity reduction practices on salt reduction; and (3) verify costs, project effectiveness, economic benefits, and impacts on wildlife habitat. 53
