1966-90 Changes-Values used represent additional depletions that have developed
since the Comprehensive Framework Study (1965 level) estimates were prepared. The
Utah Division of Water Resources provided these values and the projections to 2010.

Bonneville Unit, Central Utah Project-Present depletions from the Bonneville
Unit include reservoir evaporation, storage accrual, and irrigation uses from Currant
Creek, Strawberry, Soldier Creek, and Starvation Reservoirs. Project storage which
was accruing in Strawberry Reservoir was spilled into Soldier Creek Reservoir in 1983
because of high runoff conditions and prior storage rights of the Strawberry Valley
Water Users in Strawberry Reservoir. Elevation limitations of reservoir water surface
in Soldier Creek Reservoir further reduced the capability of storing water for project
purposes. Net depletions to the Colorado River System in 1990 are estimated to be
about 56,000 acre-feet. Based upon the present construction schedule, the depletions
to the Colorado River are expected to rise to 128,000 acre-feet by 2010.

Upalco Unit, Central Utah Project-The Upalco Unit is being reformulated as part
of the Central Utah Project Completion Act. Depletion projections were provided by
the State of Utah.

Jensen Unit, Central Utah Project-The definite plan report was revised in 1976.
The plan provided irrigation water primarily for supplemental service and water for
municipal and industrial use. Evaporation and irrigation consumptive use totaled
5,000 acre-feet in 1990. Total depletion is estimated at 15,000 acre-feet. The project
depletion would gradually increase to the full amount by 2000.

Uintah Unit, Central Utah Project-The Uintah Unit is being restructured as part
of the Central Utah Completion Act. Depletion projections were provided by the State
of Utah.

Emery County Project-The Emery County Project, as originally constituted,
depleted about 14,000 acre-feet. Utah Power & Light Company has contracted for
6,000 acre-feet of the project water for the Huntington Powerplant. Recent
negotiations between Reclamation, the power company, and the water district resulted
in the purchase of 2,000 acre-feet of additional project water. It is estimated that this
has resulted in a decrease of Emery County depletions to 10,000 acre-feet in 1990.
This assumes a two to one conversion rate (i.e., 8,000 acre-feet of project water sold to
Utah Power & Light Company will result in a 4,000-acre-foot reduction in irrigation
depletion).

Ute Indian Lands-This project is being restructured as part of the Central Utah
Completion Act. Depletion projections were provided by the State of Utah. The
