Kearney Lake in Wyoming serves as a vital water resource for irrigation purposes, with a primary dam type being earth and a height of 67 feet. Completed in 1963, the reservoir has a storage capacity of 7,500 acre-feet and covers a surface area of 193 acres. Located in Johnson County, near the city of Story, Kearney Lake is fed by the North Fork South Piney Creek and has a drainage area of 15.7 square miles.

Despite being privately owned, Kearney Lake falls under state jurisdiction and is regulated by the Wyoming State Engineer's Office. The dam has a high hazard potential but is currently in fair condition, with the last inspection taking place in August 2017. With a maximum discharge of 1,000 cubic feet per second and an uncontrolled spillway, Kearney Lake poses moderate risk, making risk management measures essential for its continued operation and safety.

Enthusiasts of water resources and climate will appreciate Kearney Lake's importance in supporting agricultural activities in the region and the need for ongoing monitoring and maintenance to ensure its structural integrity and safe operation. The reservoir's location within the Omaha District of the US Army Corps of Engineers highlights its significance in water management and underscores the critical role it plays in sustaining the local ecosystem and economy.
