Description Areas of the Soos Creek watershed (King County) don’t meet Washington State water quality standards for temperature, dissolved oxygen, or bacterial pollution. We’re developing a water quality improvement project (often called a TMDL) to restore and improve conditions for aquatic life and for people who swim, fish, or otherwise recreate in this watershed.

From April 2023 to April 2024, we’ll collect information on the quality of the water, amount of streamflow, and biological growth in the water, as well as other attributes related to the land, vegetation, and groundwater interaction. We’ll use the information to create a linked network of computer models that simulate water movement and quality through the land and in the streams. We’ll also test management scenarios in the model to develop pollution limits.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
