t'- ~ ~. ('..1 N C 13 (.. From 1972 through 1997 the CUP has stored an average of 40.717 acre-feet annually in Strawberry Reservoir and a maximum of 154.865 acre-feet in 1995. The purpose of this storage included (1) water supply for Spanish Fork-Nephi Irrigation Project. formerly known as the Irrigation Drainage System of Bonneville Unit. and (2) replacement water for the Utah Lake-Jordanelle exchange facilitated by Jordanelle Dam and Reservoir. MuniclDal and Industrial System The Municipal and Industrial System provides municipal and industrial water to Salt Lake. Wasatch and northern Utah counties. as well as supplemental irrigation water to Wasatch and Summit Counties. Jordanelle Dam and Reservoir has an active capacity of 311.000 acre-feet and are major features of the Municipal and Industrial System. Water is developed by storing Provo River flows that historically flowed into Utah Lake. Utah Lake water will be replaced by releases of project water from Strawberry Reservoir to Utah Lake. by project return flows to the lake. by water right acquisitions in Utah Lake. and by flows surplus to Utah Lake rights. The average annual exchange from Utah Lake is 96.800 acre-feet. To provide adequate water supply for Jordanelle Reservoir 21,900 acre feet annually was "exchanged" from Utah Lake to Jordanelle Reservoir. An additional 74.900 acre-feet may be required if the Spanish Fork-Nephi System is not constructed. This exchange simply meant that water which formerly flowed to Utah Lake is now impounded on the Provo River at Jordanelle. To facilitate this exchange the District is obligated to release water from Strawberry Reservoir down Diamond Fork and back to Utah Lake. thereby, replacing water now stored in Jordanelle. Diamond Fork System The Diamond Fork System provides the conveyance facilities for transbasin diversion of water from the Uinta Basin to the Bonneville Basin. T~e 7.3 mile Syar Tunnel and Sixth Water Aqueduct will deliver Bonneville Unit water and Strawberry Valley Project water from Strawberry Reservoir to Diamond Fork Creek, a tributary of the Spanish Fork River. Both Syar Tunnel and the Sixth Water Aqueduct have a flow capacity of 660 cfs. The Syar Tunnel and the Sixth Water Aqueduct are completed. Water delivered through the aqueduct will flow down Diamond Fork Creek to the proposed Monks Hollow Reservoir. From Monks Hollow Reservoir. water will flow to the Spanish Fork River through both the Diamond Fork Pipeline and the natural Diamond Fork Creek channel. Monks Hollow dam and reservoir are in the planning stages. although the Central Utah
