New Melones Lake
Sonora, Calif. – The Bureau of Reclamation will adjust operating hours at New Melones Lake beginning May 1, as part of its seasonal transition. As temperatures rise and visitation increases, Reclamation encourages visitors to plan for updated access hours, boating requirements, and available recreation services.
Boating and Mussel Prevention
Reclamation requires that all boats launching at New Melones Lake participate in a mandatory 30-day quarantine or make a reservation through New Melones Lake Marina to receive a decontamination wash to prevent the introduction of the Golden Mussel, an invasive species found in the Sacramento-San Joaquin Delta.
