Stormwater Management in Clark County
As residents of the rainy Pacific Northwest, we might assume that clean, fresh water in our streams and rivers will always be ours for the asking. But pollution, urbanization and other population pressures challenge this assumption.
Clark County administers the Clean Water Division to safeguard the quality of our streams, rivers and lakes and comply with the federal Clean Water Act and state regulations. The program's primary activities include stormwater capital improvements, water quality monitoring, public education and outreach, regulations and enforcement and stormwater maintenance. As the county's population continues to increase, the Clean Water Division is committed to keeping our waterways clean for people, fish and wildlife. Click here for an overview of our program.

Water Protection Tip for the Month - Your home improvement projects - keep it clean! With all of this sunshine, your home and yard require lots of maintenance. Make sure to keep yard debris in the compost bin and do not sweep materials into the street. When power washing, direct water to a landscape area to soak into the ground or filter the water to keep debris out of nearby stormdrains. Wash tools over buckets or sinks and place dirty water into a toilet, not down the storm drain. Do your part to prevent storm water pollution. More >>
