Buckeye FRS #2 is a flood retention structure located in Maricopa, Arizona, along the Gila River - TR. Built in 1975 by the USDA NRCS, this Earth dam stands at a height of 26 feet and spans a length of 12,155 feet, with a storage capacity of 1,930 acre-feet and a maximum discharge of 1,800 cubic feet per second. The dam serves the primary purpose of flood risk reduction and is regulated by the Arizona Department of Water Resources.

With a hazard potential rated as high and a satisfactory condition assessment as of October 2017, Buckeye FRS #2 is subject to regular inspections, with the last one conducted in October 2020. The structure has an uncontrolled spillway and outlet gates, with a spillway width of 500 feet. While the risk assessment is moderate, the dam currently does not have an Emergency Action Plan (EAP) in place, raising concerns about emergency preparedness in the event of a potential breach or failure. Overall, Buckeye FRS #2 plays a crucial role in managing flood risks in the region and underscores the importance of proactive maintenance and monitoring to ensure public safety and water resource sustainability.
