Waste Pond in Mira Mar, San Diego, California, is a private water storage facility primarily used for tailings and water supply. This Earth-type dam stands at 20 feet high and spans 760 feet in length, with a storage capacity of 6 acre-feet. While the dam is not state-regulated, it falls under the jurisdiction of the Mine Safety and Health Administration, which oversees inspections and enforcement.

Despite its non-state regulated status, Waste Pond is considered to have a significant hazard potential. The condition assessment of the dam is not available, and there is no emergency action plan in place. The dam has not been modified in recent years, and there are no inspection or maintenance records provided. With its proximity to the Los Angeles District of the US Army Corps of Engineers and the oversight of the Mine Safety and Health Administration, Waste Pond remains a notable structure for water resource and climate enthusiasts to monitor closely for any potential risks or developments.
