Warm Springs Dam, also known as Lake Sonoma, is a federal-owned structure located in Healdsburg, California, completed in 1983 for flood risk reduction. Standing at a height of 319 feet, with a storage capacity of 449,000 acre-feet, the dam poses a high hazard potential due to the risk of overtopping during major storm events or seismic activity. In the event of a breach, surrounding areas such as Healdsburg, Windsor, Sebastopol, Santa Rosa, and Guerneville could face significant impacts, highlighting the importance of effective risk management measures.

To mitigate potential risks, the US Army Corps of Engineers (USACE) has implemented various measures at Warm Springs Dam, including enhanced monitoring, surveillance, and an emergency action plan. Weather forecasts are used to manage water levels in the reservoir, while trained staff continuously monitor dam safety concerns during storm conditions. Additionally, the EAP facilitates clear communication and coordinated response actions in the event of a dam-related emergency, ensuring public safety through timely warnings and evacuation orders. Despite the identified risks, ongoing efforts by the USACE aim to minimize the impact of potential dam failures on downstream communities and infrastructure.
