Dam

The dam (National ID # CO00815) is an earthen dam built in 1912.^[2] 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.^[4]
