CWCB: Funding approved for Terrace Reservoir spillway replacement and Conejos River stream gages


From The Pueblo Chieftain (Matt Hildner):

The Colorado Water Conservation Board approved a $407,000 grant to install gauging stations in the Conejos River basin and signed off on a $1 million loan and a $1.5 million grant to replace a spillway at Terrace Reservoir. Terrace Reservoir, which backs up the Alamosa River, has had the size of its storage pool restricted by the state since the 1980s due to the inadequate size and poor condition of the reservoir’s spillway…

The Terrace Irrigation Co. owns the reservoir and has 24 shareholders. It irrigates 9,300 acres in Conejos and Rio Grande counties. The restrictions required the storage pool to remain roughly 2,000 acre-feet below the reservoir’s 15,182 acre-foot capacity. The added capacity would accommodate a 2,000-acre foot instream flow water right that is being worked on by the CWCB and the Alamosa Riverkeepers…

Construction could begin this summer once the State Engineer’s office signs off on the spillway’s design, Reinhardt said. Terrace’s project also will benefit from $2 million in Natural Resource Damage funds, which came from fines assessed to the operators of the Summitville gold mine that has since been turned into a Superfund cleanup site.

The second project to earn funding from the state called for the installation of 72 river gauges and four remote-controlled headgates by the Conejos Water Conservancy District. The district, which has 86,000 acres of irrigable land in the southwestern corner of the valley, hopes the gauges will allow for a more accurate accounting of the Conejos River’s deliveries under the Rio Grande Compact.
