Kruger Lake, located in Crook, Wyoming, is a privately owned reservoir primarily used for irrigation purposes. Built in 1937, this Earth dam stands at 15 feet high and has a storage capacity of 188 acre-feet. With a normal storage level of 94 acre-feet, the lake covers a surface area of 24 acres and has a drainage area of 0.9 square miles. Kruger Lake is fed by Kruger Creek and has a maximum discharge of 480 cubic feet per second.

Despite its low hazard potential, the dam at Kruger Lake is in poor condition as of the last inspection in August 2018. The spillway is uncontrolled, with a width of 20 feet, and outlet gates are also uncontrolled. The risk assessment for the dam is moderate, with a risk level of 3. With its location just 17 miles from Belle Fourche, Kruger Lake serves as a vital resource for the surrounding area, providing water for irrigation, fire protection, and stock, as well as serving as a small fish pond. Climate enthusiasts and water resource experts alike would find Kruger Lake to be a fascinating case study in dam infrastructure and management.
