Amethyst Basin in Victorville, California, is a locally owned dam that serves the primary purpose of flood risk reduction. Completed in 2019, this earth dam stands at a height of 46 feet and has a storage capacity of 347.7 acre-feet. With a drainage area of 6.96 square miles and a maximum discharge of 7,472 cubic feet per second, Amethyst Basin plays a crucial role in managing the ephemeral river or stream that passes through the area.

Despite its satisfactory condition assessment, Amethyst Basin poses a high hazard potential due to its location and purpose. The dam is regulated by the California Department of Water Resources (DWR) and undergoes regular inspections and enforcement to ensure its safety and functionality. The emergency action plan for the dam was last revised in February 2021, highlighting the importance of preparedness and risk management measures in the face of potential hazards.

Water resource and climate enthusiasts interested in the intersection of infrastructure and environmental conservation would find Amethyst Basin to be a fascinating case study. As a key component in flood risk reduction efforts in the region, this dam represents the intricate balance between human development and natural resource management. Its construction and operation showcase the ongoing efforts to safeguard communities and ecosystems from the impacts of extreme weather events and changing climate conditions.
