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.
