Built in 1968, this concrete dam stands at a height of 6 feet and stretches 50 feet in length. Situated in Mammoth Lakes, the reservoir is fed by Mammoth Creek and serves multiple purposes including fish and wildlife pond, flood risk reduction, and recreation in addition to water supply.
The dam at Lake Mamie has a significant hazard potential and a very high risk assessment, making it a crucial structure for water resource and climate enthusiasts to monitor. With a controlled spillway and a valve outlet gate, the dam underwent mechanical modifications in 1968. Despite not being rated for its condition assessment, Lake Mamie remains an essential resource in the region, providing vital water supply and recreational opportunities while managing flood risks in the area.
Managed by the Forest Service, Lake Mamie's risk management measures remain unspecified, but its strategic location near Mammoth Lakes and Mammoth Creek highlights its importance in the local ecosystem. As a part of the Los Angeles District, this reservoir is a key component in the water infrastructure of Mono County, California, attracting both water resource professionals and outdoor enthusiasts alike.
