Ramona, also known as Lake Ramona, is a vital water supply structure located in Poway, California. Owned by a public utility, this dam stands at a height of 228 feet and was completed in 1988. With a maximum storage capacity of 12,200 acre-feet, it serves the primary purpose of providing water for irrigation and water supply in the region.

The dam on the Green Val Road Creek is regulated and inspected by the California Department of Water Resources (DWR) for safety and compliance. Its high hazard potential is mitigated by satisfactory condition assessments, with the last inspection conducted in December 2019. Despite its critical role in water resource management, the dam has not been modified in recent years, highlighting the importance of ongoing monitoring and risk management measures to ensure the safety of surrounding communities.

As a key component of the water infrastructure in San Diego County, Ramona plays a crucial role in maintaining water supply reliability. With the potential for high hazard in case of failure, the dam's condition assessments and emergency action plans are imperative for effective management and response to any unforeseen events. Its location, design, and operational status make it a significant asset for water resource and climate enthusiasts interested in sustainable water management practices in California.
