Report

Explanation

TRPC periodically performs a current condition assessment for the 70 river, stream, and lake basins in Thurston County based on their level of urbanization, canopy cover, and riparian vegetation. In 2021, 39 basins were classified as either sensitive or intact, down from 42 in 2001. Over the same time period, the number of degraded or very degraded basins increased from 8 to 9.

Sustainable Thurston Report Card

The Sustainable Thurston Report Card tracks how well the Thurston region is doing at protecting and improving water quality. The goal includes two targets for 2035:

  • Protect small stream basins that are currently ranked as “intact” or “sensitive.”
  • Improve and restore as many “impacted” stream basins as possible.
