Storm drains are separate from sewer systems, so storm water from streets and other paved areas flows into our coastal waterways UNTREATED. Humboldt Waterkeeper is working hard to protect our environment but we can't do it alone. We need your help! 
Polluted runoff from streets, parking lots, and yards—also called "stormwater pollution"—is channeled into the storm drain system that empties directly into our creeks and sloughs, which flow to Humboldt Bay and the ocean.
