Located in Fremont County, Colorado, the Cotter Tailings dam stands as a private structure regulated by the state with a low hazard potential. Built in 1980, the earth dam reaches a height of 93 feet and a length of 5000 feet, with a storage capacity of 5400 acre-feet. The dam, primarily used for tailings purposes, overlooks Sand Creek-OS in Canon City.

With a risk assessment rating of high (2), the Cotter Tailings dam has not been rated for its condition assessment. Although it has not been inspected since September 2000, the state regulatory agency, DWR, mandates regular inspections, permitting, and enforcement. Despite its low hazard potential, the dam poses a risk that requires effective risk management measures to be implemented in the future to ensure the safety and integrity of the structure and surrounding environment for water resource and climate enthusiasts.
