Published 1998
by Nancy Breuner

This document is the Gales Creek Watershed Assessment Report prepared for the Tualatin River Watershed Council. This report contains detailed information about the Gales Creek Watershed and follows the guidelines described in the 1997 Draft Governor’s Watershed Enhancement Board’s Oregon Watershed Assessment Manual. It was written to partially satisfy the watershed assessment action item #1described in the Tualatin River Watershed Council’s Action Plan. This report should be periodically updated, as new information becomes available.
