Due to the threat of the highly invasive golden mussel, Stanislaus National Forest (STF) officials will close the Beardsley Lake Boat Ramp for the next two months. … The Tri-Dam Project is a partnership between the Oakdale Irrigation District (OID) and the South San Joaquin Irrigation District (SSJID). They noted that the closure is needed to prevent the spread to Beardsley and to downstream partners, including Pacific Gas & Electric, the United States Bureau of Reclamation, irrigators, and water treatment plants in the valley. Forest officials added, “The action is aligned with actions taken by many reservoirs in California in response to the golden mussel threat.”
