This project consists of rehabilitation of the South Crow
Diversion Dam located approximately 20 miles west of Cheyenne.
The City of Cheyenne constructed the dam in 1911 to impound and
divert the flows of South Crow Creek for municipal use. Depending
upon the time of the year, it is estimated that 0 to 3 mgd can be
diverted to Cheyenne's water system.
During the past several years, the city has not relied upon the
waters of the system and the dam has developed several structural
problems, with numerous leaks through the dam itself and severe
concrete sloughing at various locations. As Cheyenne grows, and the
use of both potable and raw water also grow and the need for additional
water also increases. The city may desire to place System Control
and Data Acquisition and metering upgrades on the South Crow Dam and
Reservoir along with the dam and reservoir rehabilitation.
In 1999 the legislature approved $80,000 to evaluate the current
condition of the South Crow Diversion Dam and to evaluate the rehabilitation
options to bring the dam up to current standards. The time needed to
test the dam conditions and the surrounding area requires a two year
program which will be completed in the summer of 2000.
RECOMMENDED LEGISLATIVE ACTION:
No legislative action is required this year.
