Reducing Stream Temperature for Salmon – Newaukum Creek

SUMMARY: Newaukum Creek is one of the two largest tributaries in the Green/Duwamish River Watershed. Over the last 100+ years, it has been degraded through land use activities such as as agriculture, timber harvesting, and residential development. Over the last 15 years, King County and other agencies have worked to restore Newaukum Creek, and it’s major tributary, Big Spring Creek. This has resulted in a significant riparian revegetation effort. The purpose of these restoration projects is to improve fish habitat and water quality.
