Kearny Lake, located in Gila River, Pinal County, Arizona, is a man-made earth dam constructed in 2000 primarily for the purpose of creating a Fish and Wildlife Pond. Managed by the Arizona Department of Water Resources, this offstream reservoir has a capacity of 203 acre-feet, with a normal storage level of 150 acre-feet and a surface area of 10.2 acres. The dam stands at a height of 28 feet and spans 1700 feet in length, with a maximum discharge capacity of 1405 cubic feet per second.

Despite its high hazard potential, Kearny Lake is currently deemed to be in satisfactory condition, as per the latest inspection conducted in January 2021. The spillway, with a width of 25 feet, is uncontrolled in nature. The reservoir's drainage area is relatively small at 0.04 square miles, contributing to its moderate risk assessment rating. With its primary purpose being fish and wildlife conservation, Kearny Lake serves as a vital resource for habitat restoration and recreational activities in the area.
