May Creek Drainage Improvement Project
Biological Evaluation Report
for chinook salmon and steelhead trout as protected under the Endangered Species Act

May Creek Drainage Improvement Biological Evaluation Report coverThe May Creek Drainage Improvement Project Biological Evaluation Report describes existing conditions on about 2,800 feet of May Creek in May Valley and evaluates the suitability of the stream as fish habitat, and physical processes affecting the stream, stream channel, and stream inhabitants. Included in the study is a review of existing literature and information about May Creek, and a qualitative general site survey which evaluates the physical and biological characteristics of the channel and the surrounding areas.

This report is produced to prepare for a county-proposed project to remove sediment and in-channel plants from May Creek to increase channel conveyance capacity and reduce flooding to adjacent pastures. This report was prepared by King County Department of Transportation.

The May Creek Drainage Improvement Project Biological Evaluation Report  is provided in Adobe Acrobat format for compatibility and speed. For help with Acrobat, please see our Adobe Acrobat help page.
