Chalk Mountain, a privately owned dam located in Minturn, Colorado, serves as a crucial water supply infrastructure along the East Fork Eagle River. Constructed in 1951 by designer R.J. Tipton, this earth dam stands at a height of 34 feet, with a total length of 960 feet, and has a storage capacity of 275 acre-feet. The dam plays a pivotal role in water resource management, primarily for water supply purposes.

With a low hazard potential and fair condition assessment, Chalk Mountain dam has been regulated and inspected by the Colorado Division of Water Resources to ensure compliance with safety standards. The spillway, with a width of 260 feet, is uncontrolled, and the dam features four valve outlet gates for water release. Despite its moderate risk assessment rating, the dam is considered to be in good operational and structural condition, meeting the necessary guidelines for emergency preparedness.

Managed by the Mine Safety and Health Administration, Chalk Mountain dam continues to play a vital role in water supply management in Eagle County, Colorado. As a key piece of infrastructure, it underscores the importance of sustainable water resource practices in the region, while also highlighting the need for continued monitoring and maintenance to ensure its long-term functionality and safety.
