What does District test the Lagoon and Creek waters for one might ask? The District tests the Lagoons and Novato Creek for pathogens in eight (8) locations throughout the community. The collected samples are taken to the Marin/Napa/Yolo/Solano County laboratory where they are analyzed and a report is submitted within 24 hours of testing. The lab results are posted below. Additional notification and testing would occur if the results fail the Marin county swimming standards. The District additionally monitors the lagoon waters in 15 locations for marine health (oxygen, PH, temperature and salinity are a few of the analysis obtained). The water quality tests happen in conjunction with flushing events.
