<br />WHAT IS THE CENTRAL UTAH PROJECT?
<br />
<br />The Central Utah Project (CUP) is a major multiple-purpose water resource
<br />project that will provide critically needed water supplies to Central Utah.
<br />Construction of the CUP as a participating project of the Colorado River
<br />Storage Project was authori zed by the Act of April 22, 1956, (70 Stat.
<br />105). The CUP consists of six units that can be constructed and operated
<br />independently. Five of the units - the Uintah, Vernal, Jensen, Upalco,
<br />and Ute Indian Units - are developments in the Uinta Basin of the Upper
<br />Colorado River Basin. The sixth and largest - Bonneville Unit - diverts
<br />water from the Uinta Basin and delivers it through the Oiamond Fork System
<br />to the Bonneville and Sevier River Basins.
<br />
<br />The Bonneville UnitLlJn_c!~r construction since 1966, was divided into six
<br />systems according to location and function for,c;,gnvenience in planning and
<br />coordlnation. These systems are the Starvation Complex (essentially
<br />completed), Strawberry Aqueduct and Collection System (under construction),
<br />Dlamond Fork Power System, Irrigation and Drainage System, Munlcipal and
<br />Industrial System (under construction), and the Bureau of Indian Affairs
<br />Developments (partially compTefedf:---fhe Bonneville Unit plan is shown in
<br />Figure 1. the unit will include: 10 new reservoirs; the enlargement of an
<br />existing reservoir, more than 140 miles of aqueducts, tunnels, and canals;
<br />five powerplants; 8 primary pumping plants; and about 200 miles of pipe
<br />drains. Water will be made available to meet present and futui"geconomic,
<br />industrial, munici]al, agriCUlturall.1&and recreation needs in Utah by pro-
