On January 6, 2023, the Metropolitan Water District of Southern California (Metropolitan) detected a single quagga mussel veliger using cross-polarized microscopy in a large volume plankton net sample collected at Metropolitan’s Foothill Feeder Pressure Control Structure, which is downstream of Castaic Lake. The veliger was confirmed as a quagga mussel by PCR and DNA sequencing.

Adult quagga mussels were previously detected by the California Department of Water Resources in Castaic Lake in August 2021.
