Prairie Lake Dam, also known as Holton City Dam, is a key water resource infrastructure located in Larkinburg, Kansas. Constructed in 1948 by the renowned firm Black and Veatch, this earth dam serves multiple purposes including water supply and recreation. With a structural height of 50 feet and a maximum storage capacity of 1022 acre-feet, Prairie Lake Dam plays a crucial role in managing the water resources of the Elk Creek-TR watershed.

Despite its importance, Prairie Lake Dam has been rated as having a poor condition assessment, indicating the need for maintenance and rehabilitation. The dam has a low hazard potential but a moderate risk due to its aged infrastructure. With a drainage area of 1.5 square miles and a maximum discharge capacity of 2952 cubic feet per second, the dam requires regular inspections and potentially some risk management measures to ensure its long-term safety and effectiveness in water resource management.

Notably, Prairie Lake Dam is under the jurisdiction of the Kansas Department of Agriculture and is regulated and inspected by state authorities. As a popular recreation spot, the dam provides opportunities for outdoor activities while also serving as a critical water supply source for the surrounding communities. With its historical significance and ongoing importance in water resource management, Prairie Lake Dam stands as a symbol of the intersection between human ingenuity and environmental stewardship in the face of changing climates and water challenges.
