<br />Lower Gunnison Basin, Colorado <br /> <br />w <br />o <br />~c.. <br />0) <br /> <br />This is the largest of the USDA salinity' control units and is located in Delta and Montrose counties. <br />Implementation was initiated in 1988 in this unit. During 1996, 7'5 new contracts were approved, <br />for a total of 302 contracts. There are 367 applications pending approval. <br /> <br />The application of salinity reduction and wildlife habitat replacement practices is rapidly increasing <br />now that the total Lower Gunnison unit is under implementation. The major practices are , <br />underground pipelines, ditch lining, land leveling, irrigation water control structures, gated pipe, <br />sprinkler and surge irrigation systems. <br /> <br />A total of three surge units were instaned in 1996. A total of 67 surge units have been installed by <br />salinity control participants in the project. The majority of the surge units have been installed by <br />the Bureau of Reclamation and the Extension Service to introduce the surge irrigation concept to <br />the Lower Gunnison project area. <br /> <br />McElmo Creek, Colorado <br /> <br />Implementation was initiated in this unit in 1990. In 1996, 25 new contracts were approved for a <br />total of 217 contracts. There are 208 applications pending approval. <br /> <br />Application of salinity reduction and wildlife habitat replacement practices is wen underway in this <br />area with sprinkler systems, underground pipelines, and gated pipe being i!,stalled. <br /> <br />Development and use or the automatic shutofffor sprinkler systems continues to be widely <br />implemented in the project to achieve better water management. <br /> <br />Uinta Basin, Utah <br /> <br />Implementation began in this unit in 1980. During 1996, 101 new contracts were approved in the <br />two counties for a total of 1,749'CRSC contracts and ACP salinity/long-term agreements since the <br />program began. There are 124 applications pending approval. , <br /> <br />The rate ofapplying salinity reduction and wildlife habitat replacement practices continues to <br />, increase. The major practices installed are sprinkler irrigation systems, improved surface systems, <br />underground pipelines and gated pipe. In this area, a large number of groups are replacing earthen <br />laterals with pipelines to provide gravity pressure for onfarm sprinkler systems. One center pivot <br />system was installed in 1996. <br /> <br />Demonstration plot activities continued on Ute Indian Tribal land to: illustrate the benefits of <br />sprinkler irrigation; teach principles of irrigation scheduling; and provide data on crop variations, <br />yields, and costs to deterinine fair market lease agreements. Special emphasis is being placed on <br />working with individual farmers on principles of irrigation water management. <br /> <br />2 <br /> <br />
