Water Quality Protection District

The Lewis and Clark County Water Quality Protection District (WQPD) serves the Helena valley and surrounding areas (WQPD map)(PDF, 4MB). Our mission is to preserve, protect, and improve water quality and quantity within the boundaries of the WQPD District. We do this by collecting stream and groundwater data, conducting investigations and outreach on local water issues, and assisting residents to better understand and manage their water resources.
