Stagecoach Reservoir Project
(Upper Yampa Water Conservancy District)

Introduction

The Stagecoach Reservoir site is located on the Yampa River
about 3 miles east of the towns of Phippsburg and Oak Creek.
The proposed project would create a reservoir of about 33,700
acre-feet, of which 3,500 acre-feet would be inactive storage.

Study Status

The District submitted a project application in September,
1982. CWCB staff met with District representatives, visited the
project site, and discussed the project with them. The District
decided to fund the required feasibility study with its own
money. Colorado-Ute Electric Association, Inc. (Colorado-Ute),
performed the study.

Proposed project

The Stagecoach Reservoir would be created by the
construction of a dam with a maximum height of 145 feet above
streambed and a crest length of nearly 900 feet. The reservoir
would have a water surface area of approximately 780 acres at an
elevation of 7,200 feet. The outlet works would be a gated,
66-inch diameter steel pipe tapering to 30-inches, thus allowing
for the possible addition of a hydropower component to the
project at a later date.

The total cost of the project is presently estimated at
$12,000,000. Additional analysis of dam designs, which will be
necessary, could affect this estimate.

The yield of the project is estimated at 30,000 acre-feet
per year. However, it appears that there is presently a demand
for only about 15,000 acre-feet per year.

Colorado-Ute, in a letter agreement with the District to
which the Board is not a party and which was entered into prior
to the Board acting on the project, has indicated that it is
willing to purchase 10,000. acre-feet per year at $35 per
acre-foot. The agreement notes that:
