Blackman_* is a federal-owned dam located in Mesa, Colorado, along the Cottonwood Creek. Built in 1911 for the primary purpose of recreation, this Earth-type dam stands at a height of 22 feet with a maximum storage capacity of 90 acre-feet. With a significant hazard potential, the dam has a spillway width of 12 feet and a maximum discharge of 15 cubic feet per second.

Despite its age, Blackman_* has not been rated for its condition assessment and lacks updated emergency action plans. The risk assessment for the dam is moderate, highlighting the need for risk management measures to ensure the safety of downstream communities and the surrounding environment. As a significant water resource in the area, Blackman_* serves as a reminder of the importance of maintaining and monitoring aging infrastructure to mitigate potential risks and ensure sustainable water management practices in the face of changing climate conditions.
