Superior, located in Boulder County, Colorado, is home to a significant water supply dam known as the Superior Dam on Coal Creek-OS. Completed in 1994, this earth-type dam stands at a height of 83 feet and has a storage capacity of 500 acre-feet, with a normal storage level of 400 acre-feet. The dam serves the primary purpose of water supply for the local community, making it a crucial infrastructure for ensuring water availability in the region.

With a high hazard potential but a satisfactory condition assessment as of October 2020, the Superior Dam is subject to regular inspection, enforcement, and permitting by the Colorado Department of Water Resources (DWR). The dam's spillway, with a width of 2 feet, is uncontrolled, and it has a maximum discharge capacity of 41 cubic feet per second. Despite its high risk potential, the dam's risk assessment is classified as moderate (3), indicating the need for ongoing risk management measures to ensure the safety and integrity of the structure.

Overall, Superior Dam plays a vital role in water resource management in the area, providing essential water supply while also posing challenges in terms of safety and risk mitigation. As climate change continues to impact water resources and infrastructure, the maintenance and monitoring of dams like Superior will be crucial to ensure the resilience and sustainability of water systems in the face of evolving environmental conditions.
