Barnett is a privately-owned dam located in Rancho Murieta, California, along Barnett Creek. Built in 1948 by the Natural Resources Conservation Service, this earth dam stands at a height of 18 feet and spans 688 feet in length. With a storage capacity of 115 acre-feet, Barnett serves multiple purposes including flood risk reduction, irrigation, and water supply for the surrounding area.

Managed by the California Department of Water Resources, Barnett is regulated, permitted, inspected, and enforced to ensure its safety and functionality. The dam has a significant hazard potential but has been assessed as satisfactory in condition, with the last inspection conducted in January 2021. Despite its age, Barnett remains a crucial infrastructure for managing water resources in El Dorado County, California, and continues to play a vital role in safeguarding the local community from potential flood risks.

As an essential component of the region's water management infrastructure, Barnett serves as a testament to the ongoing efforts to balance water resource utilization with climate resilience. With its strategic location and multi-purpose functionality, this dam underscores the importance of proactive maintenance, inspection, and emergency preparedness to mitigate potential risks and ensure the sustainable management of water resources in the face of changing climate conditions.
