Clark County invites residents to learn about stream health

Clark County is inviting residents to learn about the health of their local streams in the most recent stream health report released by Clark County Public Works.

The report and interactive maps, along with explanations of key water quality parameters and indices are available online at https://clark.wa.gov/stormwater.

Public Works staff collected data from 2010 to 2020 to determine biological stream health. After analyzing the results, staff created maps that compare stream health ratings with the 2010 report, identify trends, and give a snapshot of which streams are meeting state standards for key water quality parameters. The report also includes a query table for users who want to dig further into the data.

According to the county, results on stream health were mixed. Smaller, urban streams often rate as poor, while larger and more rural streams are typically in the fair to good range. Comparisons between the last report show most streams are in similar conditions.

The map primarily covers unincorporated Clark County.
