Located in Gila, Arizona, the Slack dam serves a vital purpose in flood risk reduction along the Pinto Creek - TR stream. Owned privately, but regulated by the Arizona Department of Water Resources, this rockfill dam stands at a height of 50 feet and stretches 587 feet in length. Completed in 1995, it has a normal storage capacity of 42 acre-feet and a maximum storage of 59 acre-feet, covering a surface area of 4 acres with a drainage area of 0.12 square miles.

Despite its low hazard potential, Slack Dam has a moderate risk assessment rating of 3, and its condition has not been formally assessed. With a last inspection date in March 2014, the dam is subject to regular inspections every 5 years to ensure its structural integrity and compliance with state regulations. Equipped with an uncontrolled spillway and emergency action plan, this dam plays a crucial role in managing water resources and mitigating potential flood risks in the region.

Supported by the Los Angeles District of the US Army Corps of Engineers, Slack Dam stands as a testament to effective water management practices in Arizona. Its strategic location in Roosevelt Lake Estates highlights the importance of private-public partnerships in safeguarding communities and ecosystems from the impacts of extreme weather events and climate variability. For water resource and climate enthusiasts, Slack Dam serves as a symbol of resilience and innovation in the face of changing environmental conditions.
