Town Wash Dam, also known as Jim Wilson Detention Basin, is a concrete structure located in Mesquite, Nevada, designed primarily for flood risk reduction along the Town Wash river. Completed in 1992, the dam stands at a height of 41 feet with a hydraulic height of 32 feet, providing a storage capacity of 485 acre-feet. With a structural height of 45 feet and a length of 900 feet, the dam plays a crucial role in mitigating the high hazard potential posed by potential flooding in the region.

Managed by the local government and regulated by the Nevada Department of Water Resources, Town Wash Dam has been assessed to be in fair condition during its most recent inspection in February 2022. Despite its fair condition, the dam's emergency action plan status and risk assessment have not been updated recently, highlighting the importance of regular monitoring and maintenance to ensure its effectiveness in flood risk reduction. With an uncontrolled spillway and one outlet gate, the dam serves as a critical infrastructure for the community's safety and well-being.

In the face of changing climate patterns and increasing water resource challenges, Town Wash Dam stands as a vital asset in protecting the residents of Mesquite from potential flooding events. As climate enthusiasts and water resource advocates, it is imperative to support ongoing efforts to maintain and improve the dam's infrastructure to enhance its resilience and effectiveness in safeguarding the community against flood risks.
