Be a Steward of Stormwater and help keep pollution out of Lake Tahoe! Most of the nutrients and fine sediment particles that cause clarity loss originate from roadways in our local commer­cial centers and neighborhoods. At each event, volunteers will: sweep the storm drain free of debris, pick up litter, install English and Spanish markers onto storm drain grates, chalk “SOS,” “No dumping,” etc., and learn about the impacts stormwater runoff has on Lake Tahoe water clarity.
