Glacier Spg Retaining Pond, located in Mesa, Colorado, was completed in 1934 by the USDA Forest Service for the primary purpose of serving as a fish and wildlife pond. This Earth-type dam structure stands at a height of 13 feet with a hydraulic height of 9 feet, creating a storage capacity of 15 acre-feet. The pond is situated along Mesa Creek and is owned and regulated by the Forest Service, making it a significant resource for the local ecosystem.

Despite its age, the Glacier Spg Retaining Pond remains in a not rated condition, with a significant hazard potential due to its location and design. The pond has a moderate risk assessment rating and lacks emergency action plans and regular inspections. With a capacity of 15 acre-feet and a spillway type classified as uncontrolled, the pond plays a vital role in supporting fish and wildlife populations in the area, as well as providing recreational opportunities for visitors. As climate change continues to impact water resources, the management and maintenance of structures like the Glacier Spg Retaining Pond will be crucial for preserving the ecological balance in the region.
