in the preferred plan unless a major problem is found as a result of this
study. The second priority is Beaver Creek Dam site if Plateau is not
feasible. If neither of those sites are found to be feasible, additional
evaluations will be necessary to determine other suitable sites. The studies
will include: topography of the Plateau and Beaver dam and reservoir sites;
determination of the optimum reservoir size; preparation of appraisal
designs and costs for both sites; evaluation of hydrology; and geotechnical
field studies of the preferred dam site.

2.c.3. Dove Creek Canal Stor " ry Site Stor sites along the Dove Creek
Canal (a facility of the Dolore ', jeet) are aided to provide water during
periods the canal is not operated Cris."= ll capacity. These sites include,
though not limited to, Sharps Cr`'` reservoir and Monument Creek
reservoir.
2.c.4 Use of Existing Storage Sites — The potential to utilize all or portions
of existing reservoirs will be evaluated. The existing reservoirs include:
Totten, Groundhog, Narraguinnep, and McPhee.
2.d. Preliminary analysis of the Dolores Project facilities has shown that the Dove
Creek Canal can carry water for an additional 4,100 acres through Reach 1, about
2,300 acres through Reach 2, and 1,100 acres through Reach 3. The available
capacity of the canal to serve additional lands will be specifically determined. In
order to utilize Dolores Project facilities, a carriage contract is necessary with the
Bureau of Reclamation.
The existing pumping plants to serve irrigated lands can potentially serve an
additional 1,200 acres provided that distribution pipelines are constructed. In order
to utilize this existing capacity, W E T PACK anticipates increased irrigation up to
the capacity of the existing facilities. The extra capacity of the pump stations will
be finally determined.
The delivery pipelines and pumps necessary to convey the water from the Dove
Creek canal to the potentially irrigated lands will be planned and sized with
construction cost estimates.
