Reservoir is the primary, diversion point to place water in storage in the
Union Park Reservoir, and further it is to be used as the lower reservoir
for the hydroelectric pumped storage feature of the project. The major
features of the project are shown in Figure / 1-2. A general description
of the different features of the project is as follows:

1. Proposed Union Park Dam and Reservoir
The proposed Union Park Dam and Reservoir are shown on Figure / 1-2.
Lottis Creek, a tributary of Taylor River, flows into Union Park
from the south and meanders westward to the dam site. The proposed
alternate dam sites are located at or near the mouth of Union Canyon.

The Canyon cross sections should permit the consideration of
di fferent types of dams. The permi tted dam types coul d i ncl ude
earth-core rockfill, roller compacted concrete, concrete' gravity and
asphalt or concrete faced rockfill.

The dam axis will be located at one of two alternate sites as
follows:

(a) The south abutment is located at a point which bears South
15020119" vJest a distance of 22,332.95 feet from the Northwest
corner of Section 21, Township 14 South, Range 82 West of the 6th
P.M., Gunni son County, Colorado. The dam axi s intersects Lott is
Creek at a point which bears South 15020119" West a distance of
21,700 feet from the Northwest corner of said Section 21, or
