Wondering about swimming or boating in the river?
Our rivers and streams are so much cleaner since the first Clean Water Act was passed in 1972, but there are still times when water may not be clean enough for swimming or boating. Rainfall can wash bacteria, nutrients, pesticides, salt, sand, trash, and even dirt off parking lots, lawns, streets and farm fields into our rivers and streams. Rainfall can also overwhelm our sewer systems and cause them to overflow and dump untreated sewage into our rivers and streams.
E. coli bacteria is an “indicator” in the water for human pathogens (bacteria, viruses, and other diseases) that might make people sick if they use the water for swimming or boating. A collaborative of many different groups monitor E. coli at many locations throughout the watershed from April through October, so if you are looking to go boating or swimming check the data first!
