Delta Control, located in Delta, Colorado, is a vital structure managed by the local government for water supply purposes. This earth dam on the Gunnison River-TR stands at 24 feet high and has a hydraulic height of 26 feet, serving as a crucial resource for the region since its completion in 1961. With a low hazard potential and fair condition assessment, Delta Control ensures a reliable water storage capacity of 54 acre-feet, with a normal storage capacity of 34 acre-feet, catering to the water needs of the area.

The dam, primarily made of stone core and resting on rock and soil foundations, spans a length of 470 feet and has a spillway width of 12 feet. Despite its age, Delta Control undergoes regular inspections every six years to maintain its operational efficiency and safety standards. With a maximum discharge capacity of 353 cubic feet per second, this structure plays a crucial role in regulating water flow and ensuring water resource management in the region, contributing to the overall climate resilience and sustainability efforts.

As a state-regulated and permitted facility with enforcement and inspection mechanisms in place by the Colorado Department of Water Resources (DWR), Delta Control exemplifies responsible water infrastructure management. With a risk assessment indicating high risk level 2, the dam's management continues to monitor and implement risk management measures to safeguard the surrounding communities and enhance the resilience of the water supply system. Delta Control stands as a testament to the importance of effective water resource management in mitigating climate-related challenges and ensuring sustainable water supply for the future.
