Description Cooler water temperatures are predicted for hypothetical conditions with mature riparian vegetation, improved microclimate, reduced width, and increased groundwater inflows. Potential maximum temperatures could be less than the threshold for lethality of 23°C but greater than the water quality standards in most of the stream segments that were evaluated.

This technical assessment uses shade as a surrogate measure of heat flux. In addition to load allocations for shade, other management activities are recommended for compliance with water quality standards for water temperature, including measures to reduce channel widths.
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.
