Terrace Reservoir

Terrace Reservoir is located in Conejos County, Colorado northwest of the town of Capulin. It is surrounded by the Rio Grande National Forest. The reservoir is owned by the Terrace Irrigation Company, which uses the water it stores to irrigate agricultural crops in the nearby San Luis Valley.

State wildlife area

The lake and the land immediately surrounding it are also designated as the Terrace Reservoir State Wildlife Area. The wildlife area offers hunting and fishing.

Dam

The dam is an earthen dam built in 1912. It is split into two sections, with a mountain in the middle separating the two. The reservoir drains to the Alamosa River through a penstock on the southern segment of the dam. The spillway, which is on the northern dam segment, was replaced sometime after 2012.
