Continental and Santa Maria Dams Rehabilitation Project

December, 19B7

A. CONTINENTAL DAM

Introduction

The Continental Dam and Reservoir are located on North
Clear Creek. a tributary of the Rio Grande River, about 12
miles southwest of Creed. The reservoir was constructed in
1925. It has a decreed capacity of 26.716 acre-feet. Water
from this reservoir serves agricultural acreage in the San Luis
Valley.

Problem

The State Engineer has restricted storage in Continental
Reservoir to 15,000 acre-feet due to concern over embankment
integrity at higher levels of storage. which concern was
prompted by excessive leakage in the embankment. As a result
of this restriction, the owners of the reservoir had a
feasibility ,study prepared by Hydro-Triad. Ltd.. a Denver
consulting engineer, to determine how to have the restriction
lifted. That study has now been completed and is the basis for
the recommendation on this dam.

Proposed Repairs

The feasibility study examined four alternate solutions to
the embankment leakage problem. The recommended alternative is
to remove the upstream face of the dam embankment where the
leakage paths have been identified and replace this area with
an imperious material (clay or plastic material). The total
estimated cost of these repairs is $193,OOO~

Proposed Financinq

The owner has requested. and the Board recommends because
of the importance of this reservoir under the Rio Grande
Compact, a 100 percent loan:

CWCB loan at 5\ interest

$193,000

Under this financing arrangement, the company will have to pay
the CWCB $12,554.65 per year for 30 years, for a total
repayment of $376,639.50.
