spanish fork nephi irrigation system project area summary planning & reports distribution pipeline / pumping plant project map

distribution South Utah County Distribution System The Salem Bench Distribution System will provide project water for 1,200 to 2,000 acres of full service lands. This area is often referred to as the Goosenest area in Reclamation literature. Current plans are to turn water out of the Salem Bench Pipeline at three locations and to discharge water into regulation ponds. These ponds would be used to pressurize a closed irrigation system. Presently, there is no distribution system in the Salem Bench area. Juab County Distribution System The service area for the Juab County Distribution System includes the lands adjacent to Mona Reservoir, Nephi City, lands in the Elberta area and south Mosida area and lands west of Mona Reservoir. The lands east of Mona Reservoir and the lands adjacent to Nephi City are currently serviced by both sprinkler irrigation systems and open ditch systems. Much of the water for the sprinkler irrigation systems comes from wells. The distribution system for these two areas and the lands west of Mona Reservoir will service between 21,000 and 24,000 acres, and provide an annual average delivery of 42,000 acre feet of project water. The land west of Mona Reservoir is known in Reclamation literature as the West Mona Development and is 1,950 acres. The West Mona Development will require either a pumping plant on Mona Reservoir or a delivery pipeline from the Mona-Nephi Pipeline. This area will require a completely new distribution system. Reclamation has completed several reconnaissance-level designs for this distribution system for cost estimating purposes. Deliveries to the Elberta area will be accomplished by releasing project water from Mona Reservoir into Current Creek. Additional studies will determine the need for project features to make this delivery and whether the existing distribution system has sufficient capacity to make project deliveries. Project features for the Elberta area may include a new diversion dam on Current Creek, a pipeline, and an enlargement of the existing Elberta Canal.
