Interrelationships of CREST and Salinity Programs Al Jonez, U8BR, reviewed the data that was in the May 2 report put out by the USBR Salinity Control Office on salinity benefits from the CREST Program. The May 2 report showed that ,the reduction in salinity resulting from an opera- tional weather modification program will be needed in conjunc- tion with the planned salinity control activities by the USBR and Department of Agriculture in order to assure that the goal of no increase in salinity would be realized over the long-term period of development of the Colorado River Basin. Forest Service Plans for Vegetation Management to Increase Streamflow Tom Elson reported on the USFS, plans in the Rocky Mountain Region. He stated that final environmental impact statements are scheduled to be issued over the next three years for t,,;elve NatiQnal Forests that overlie part of the Colorado River Basin. He identified the relationships between the USFS's National program, identifi~d as the RPA Program, the regional program which integrates the national goals within the regional forest's resources and needs, and down to the local National Forests which identify decisions pn how blocks of forest lands will be managed over time to achieve local, regional, and national goals. He stated tha~' water yield increase come from four different activities: First, and most importantly, the timber harvesting program; second, specific activities designed to increase water yield such as clear-cutting non-commercial forests, converting brush la,nd to grass lands, and snow fences; third, wildlife habitat improvements such as maintenance of forest opening and prescribed burns in forests that both enhance habitat but which also result in increase in water yield; and forth, inadvertant activities such as road con- struction and insect infestations that kill off trees. He summarized the water yield increase plans for a few of the National Forests in the Rocky Mountain Region, showing the relationship between the maximum potential increase and the proposed plans, which may be only about one tenth of the maximum potential. Comments were made by the committee that the reports should present the reasons why the proposed plans were less than the potential and, the different factors that C-33
