Snohomish is full of waterways and the city is both proud and dedicated to help protect them. The city is flanked by the Snohomish River to the South, the Pilchuck River to the east and Cemetery Creek to the west. Blackman’s Lake sits squarely in the middle and boasts a long history of community interest. The city is a phase II municipality and manages its own national pollutant discharge elimination system (NPDES) permit.
