sure sprinkler systems and improved a surface irrigation system with un- derground pipeline and gated pipe. Wildlife habitat practices are also being applied. A total salt-load reduction of 4,900 tons has been achieved. 3. LOWER GUNNISON BASIN UNIT Construction of the Winter Water Alternative was initiated in Fiscal Year 1990 and will continue in 1991. The five-year plan of development provides for eliminating winter livestock water deliveries made through the Uncompahgre VaHey Water Users canal system. Stockwater wiH be provided by expanding the existing culinary water system with small- diameter pve pipe and stock tanks. Construction of the water delivery system is being accomplished by the local water users through construc- tion cooperative agreements with Reclamation. Funding for salinity control contracts with farmers and groups in the Lower Gunnison area has been available for three years. As of September 30, 1990 forty contracts have been signed by participants. Since the program was initiated, eighteen miles of pipelines, gated pipe and con- .crete-lined ditch have been installed. Surge irrigation systems, sprinkler systems, water control structures and wildlife habitat practices have also been installed. A salt-load reduction of 2,000 tons per year has been achieved. 4. PRICE-SAN RAFAEL RIVERS UNIT A planning report/environmental impact statement wiH be completed in Fiscal Year 1991 for salinity-related irrigation improvements in these tw~ river basins. The plan calls for Reclamation to install 97 miles of piped laterals to create pressure for sprinkler systems to be installed under the SCS on-farm program. The plan would also provide culinary water to replace winter stockwatering from the canals. This unit wiH reduce salinity by 162,900 tons per year. The unit's cost effectiveness has been estimated at $55 per ton of salt removal. 5. DIRTY DEVIL RIVER UNIT A planning report concluding the study was approved in June ofl9 87. 6. SAN JUAN RIVER UNIT A planning report/environmental statement wiH be completed in Fiscal Year 1991 for the salinity-related rehabilitation of the 19.5 miles of the Main Canal, 3.9 miles of the Gravity Extension Lateral, 2.3 miles of the East Highline Lateral and I mile of the Wet Highline Lateral. It is esti- mated that these improvements wiH reduce salinity by 27,000 tons per 69
