Dad Dahl Detention #2 Dam, located in Sweetwater, Wyoming, is a federal-owned structure primarily designed for debris control along the South Barrel Springs Draw. Constructed in 1963 by the Bureau of Land Management, this gravity dam stands at a structural height of 30 feet with a hydraulic height of 26 feet, spanning 800 feet in length. With a storage capacity of 128.6 acre-feet, the dam serves as a crucial resource for managing water flow and preventing debris buildup in the area.

Despite its importance, the dam is currently rated as having a low hazard potential with a poor condition assessment, indicating the need for maintenance and upgrades to ensure its long-term stability. The last inspection in July 2016 highlighted the need for improvements, with a moderate risk assessment rating of 3. With its uncontrolled spillway and lack of outlet gates, there are concerns about the dam's ability to handle increased water flow during extreme weather events, highlighting the need for ongoing monitoring and risk management measures.

As climate change continues to impact water resources and weather patterns in the region, the Dad Dahl Detention #2 Dam plays a crucial role in maintaining water quality and preventing potential hazards. With its federal ownership and regulation by the Bureau of Land Management, there is a clear responsibility to ensure the dam's safety and effectiveness for the surrounding community. By addressing the identified maintenance needs and implementing risk management strategies, the dam can continue to fulfill its important role in water resource management for years to come.
