El Toro Reservoir, located in Mission Viejo, California, is a vital water resource facility owned by a public utility agency. Completed in 1967, this earth dam structure stands at a height of 113.3 feet, with a maximum storage capacity of 877 acre-feet. With a primary purpose of water supply for irrigation and domestic use, El Toro Reservoir plays a crucial role in ensuring water security for the surrounding community.

Managed by the California Department of Water Resources (DWR) and subject to state regulation for safety and inspection, El Toro Reservoir has a high hazard potential but was assessed to be in satisfactory condition as of September 2017. The dam overlooks the Trabuco Creek and has a drainage area of 0.04 square miles, making it a key player in water management within Orange County. Despite its high hazard potential, the reservoir's emergency action plan and risk management measures are not explicitly detailed in the available data, leaving room for further investigation into its resilience in the face of potential emergencies.

El Toro Reservoir's strategic location and substantial storage capacity make it a critical asset for water supply in the region. As climate change continues to impact water resources, understanding and enhancing the safety and efficiency of facilities like El Toro Reservoir becomes increasingly important. With its significant role in water supply infrastructure, this reservoir serves as a reminder of the ongoing need for sustainable water management practices in the face of a changing climate.
