… The invasive golden mussel has been confirmed at Silverwood Lake in San Bernardino County and Pyramid Lake in Los Angeles County, according to the Department of Water Resources, the California Department of Fish and Wildlife and California State Parks. The two lakes are now the southernmost reservoirs in the State Water Project where the mussels have been found. … The mollusk’s fast march across California could spell trouble for the state’s vast network of canals, reservoirs and pipelines, which shuttle water from the San Joaquin Delta to other parts of the state.
