Bourjaily Dam, located in Johnson County, Iowa, was completed in 1971 by the USDA NRCS and serves multiple purposes, including fire protection, stock, and a small fish pond. This private dam stands at a height of 22 feet and stretches 576 feet in length, with a storage capacity of 50 acre-feet and a surface area of 3.9 acres. Despite its low hazard potential, the dam is regulated by the Iowa Department of Natural Resources and undergoes periodic inspections to ensure its safety and integrity.

The dam, situated on the TR-North Branch Old Mans Creek, is designed as an earth dam with a soil foundation. While it currently does not have any outlet gates or spillway controls, its uncontrolled spillway type poses a moderate risk level. The dam's risk assessment indicates a potential for moderate consequences in the event of a failure, prompting the need for adequate risk management measures to be implemented. Overall, Bourjaily Dam presents a notable feature in the local landscape, showcasing the importance of water resource management for the community.

Enthusiasts of water resources and climate will find Bourjaily Dam to be a fascinating structure, with its unique design and multi-purpose functionality. As a privately owned dam, it highlights the role of individuals in managing water resources for various needs, from fire protection to recreational activities. With its location in an area prone to moderate risk, the dam serves as a reminder of the importance of regular inspections and risk management strategies in ensuring the safety and sustainability of water infrastructure.
