Watershed Assessment Library
Library Introduction
In the following you will find a list of watershed assessments sorted by the Oregon Plan Reporting Basins.  This compilation is a work in progress and will be updated as watershed assessments become available to OWEB.  If a watershed assessment title is not linked then no electronic copy is available of the document.  If no electronic copy is available, a hard copy document is on file at OWEB's Salem office.  ODFW's Data Clearinghouse provides a centralized accumulation and distribution service for Oregon's natural resource data.  The Data Clearinghouse website houses reports, data files, databases, GIS maps and other natural resource information; especially those funded by OWEB, from watershed councils, and Oregon's natural resource agencies.
