Subsequent legislation, Public Law 96-375 of October 3, 1980, specifically authorized feasibility-level studies on the Lower Gunnison Basin and nine other salinity control units. Previous and Related Investigations Dallas Creek Project The Dallas Creek Project, authorized in 1968, is presently under construction. The project will provide municipal, industrial, and irrigation water and flood control for a service area encompassing the Lower Gunnison Basin Unit study area and other portions of Montrose, Delta, and Ouray Counties. The principal project feature, Ridgway Reservoir, will be formed by Ridgway Dam on the Uncompahgre River about 6 miles north of the town of Ridgway and will have a storage capacity of 80,000 acre-feet. Water supplies are expected to include 22,600 acre- feet for municipal purposes, 5,500 acre-feet for light industrial use, 900 acre-feet for supplemental irrigation of land south of the Lower Gunnison Basin Unit study area, and 10,300 acre-feet for supplemental irrigation within the study area. Water will be distributed through existing fscilities or facilities constructed by the Tri-County Water Conservancy District or the water users. Uncompahgre Project The Uncompahgre Project was authorized for construction in 1903 following passage of the Reclamation Act in 1902. Most of the project facilities were constructed before 1915, and the last feature, Taylor Park Reservoir, was completed in 1937. Irrigated lands served by the Uncompahgre Project are included within the study area of the Lower Gunnison Basin Unit, and are located in the lower Uncompahgre Valley surrounding the town of Montrose and extending northwest along both sides of the Uncompahgre River to Delta, a distance of 34 miles. Project features include Taylor Park Dam and Reservoir, Gunnison Tunnel, 7 diversion dams, 138 miles of main canals, 414 miles of laterals, and 216 miles of drains. The system diverts water from the Uncompahgre River and from the Gunnison River to the east through the Gunnison Tunnel to serve 83,000 acres of project land. The Uncompahgre Valley Water Users Association operates and maintains the project. Uncompahgre Project Improvement and Extension Because of the age of the Uncompahgre Project facilities, many are seriously deteriorated and in need of replacement. The Colorado River Water Conservation District, Uncompahgre Valley residents, local and State entities, and others requested that the Bureau of Reclamation undertake a study on improving and extending the Uncompahgre Project. The study was conducted and a report presenting the results completed in 2 ()Q0902
