Gowan Detention North Dam, located in Las Vegas, Nevada, is a vital structure owned by the local government for flood risk reduction along the Las Vegas Wash-TR. With a height of 28 feet and a storage capacity of 1492 acre-feet, the dam serves multiple purposes including flood risk reduction, fish and wildlife pond creation, and recreation. The dam is primarily an earth-type structure with a multi-arch core and soil foundation, designed to manage high hazard potential and fair condition assessment.

The dam features an uncontrolled spillway and one outlet gate, with a surface area of 10 acres. While the dam's hazard potential is rated as high, its risk assessment falls within the moderate category. Regular inspections are conducted, with the last assessment completed in May 2021. The dam's emergency action plan (EAP) status and risk management measures remain undisclosed, highlighting the need for continued monitoring and preparedness in the face of potential climate-related challenges in the region. Water resource and climate enthusiasts can appreciate the engineering and operational complexities involved in managing water infrastructure in dynamic environments like Las Vegas.
