<br />128,000 acre-feet by 2010,

<br />Upalco Unit, Central Utah Project
<br />
<br />The Upalco Unit is being reformulated as part of
<br />the Central Utah Project Completion Act,
<br />Depletion projections were provided by the State
<br />of Utah,
<br />
<br />Jensen Unit, Central Utah Project
<br />
<br />The definite plan report was revised in 1976,
<br />The plan provided irrigation water primarily for
<br />supplemental service and water for M&I use,
<br />Evaporation and irrigation consumptive use
<br />totaled 5,000 acre-feet in 1990, Total depletion
<br />is estimated at 15,000 acre-feet, The project
<br />depletion would gradually increase to the full
<br />amount by 2000,

<br />The Uintah Unit is being restructured as part of
<br />the Central Utah Completion Act, Depletion
<br />projections were provided by the State of Utah,
<br />
<br />Emery County Project
<br />
<br />The Emery County Project, as originally
<br />constituted, depleted about 14,000 acre-feet,
<br />Utah Power & Light Company has contracted
<br />for 6,000 acre-feet of the project water for the
<br />Huntington Powerplant, Recent negotiations
<br />between Reclamation, the power company, and
<br />the water district resulted in the purchase of
<br />2,000 acre-feet of additional project water, It is
<br />estimated that this has resulted in a decrease of
<br />Emery County depletions to 10,000 acre-feet in
<br />1990, This assumes a two to one conversion
<br />rate, i.e" 8,000 acre-feet of project water sold to
<br />Utah Power & Light Company will result in a
<br />4,000-acre-foot reduction in irrigation depletion,

<br />Ute Indian Lands
<br />
<br />This project is being restructured as part ofthe
<br />Central Utah Completion Act, Depletion
<br />projections were provided by the State of Utah,
<br />The Ute Indian water rights were settled, and
<br />the tribe was allocated approximately
<br />100,000 acre-feet of additional depletion, This
<br />depletion is anticipated by the year 2040,
<br />
<br />Division of Water Resources Projects
<br />
<br />In August 1984, the DWR of the State of Utah
<br />determined that about 16,000 acre-feet of water
<br />would be depleted in 1990 by DWR sponsored
<br />projects, DWR estimates that depletions will
<br />increase to 28,000 acre-feet by 2020,
<br />
<br />Emery County Powerplants
<br />
<br />Both units of the Huntington Powerplant of
<br />Utah Power & Light Company were in service in
<br />1983, Water-use records indicate that the
<br />powerplant uses up to 12,000 acre-feet a year,
<br />Two units of the Hunter Powerplant of Utah
<br />Power & Light Company, located near
<br />CastIedale, were on line in 1983, Water-use
<br />records for this plant also indicate a maximum
<br />annual use of about 12,000 acre-feet, One
<br />additional unit began operation in March 1983,
<br />Construction of the fourth unit has been
<br />suspended indefinitely, It was assumed that
<br />each unit would require 6,000 acre-feet a year,
<br />These figures result in an estimated use of
<br />30,000 acre-feet,
<br />
<br />Water from these two powerplants will come
<br />from (1) the purchase of 8,000 acre-feet of Emery
<br />County Project water, (2) the purchase of up to
<br />24,000 acre-feet of private irrigation water
<br />rights, and (3) the development of 3,000 to
<br />5,000 acre-feet of new water made possible by
<br />construction of Electric Lake Dam, Water
<br />surplus to powerplant needs is leased back to
<br />the irrigation users,

<br />Most of the water developed for the Emery
<br />County powerplants comes from the purchase of
