Sidehill Detention Basin Dam, located in Sparks, Nevada, was completed in 1998 with the primary purpose of flood risk reduction along the Sun Valley Creek. This earth dam stands at 14 feet high with a hydraulic height of 12 feet and a length of 200 feet, providing a maximum storage capacity of 71 acre-feet. Despite its significant hazard potential, the dam's condition assessment is currently poor, indicating a need for maintenance and improvement to ensure its effectiveness in managing flood risks in the region.

The dam features an uncontrolled spillway with a width of 40 feet and an outlet gate for water release. The inspection frequency is set at every three years, with the last assessment conducted in June 2021. The risk assessment for Sidehill Detention Basin Dam is moderate, suggesting a need for proactive risk management measures to mitigate potential hazards. With its location in Washoe County, Nevada, and its critical role in flood risk reduction, this dam serves as a vital infrastructure for water resource and climate enthusiasts to monitor and support for the safety and protection of the surrounding community.
