Description

Abstract: The Upper South Yamhill River watershed assessment is a publication of the Yamhill Basin Council (YBC) and is a reference tool for watershed residents. It contains information gathered from many different sources about past and present conditions in the watershed. The assessment also identifies areas where information is lacking. The assessment includes the topics of a Watershed Overview, Historical Conditions, Channel Habitat Types, Vegetation, Riparian and Wetland Conditions, Channel Modifications, Sediments, Hydrology and Water Use, Water Quality, Fish Habitat and Barriers, Restoration and Enhancement Projects, and a Watershed Conditions Summary.

Purpose: The purpose of this assessment is to provide watershed residents, landowners, and decision-makers with basic objective information regarding land and water resources in the Upper South Yamhill watershed, which includes all of the drainages to the South Yamhill River upstream of Willamina Creek. This document may serve as a baseline for designing restoration projects and will aid the Yamhill Basin Council and community members in developing monitoring plans. It is also tied to an ongoing process of community-based land use planning; the information contained will need to be updated as local needs and objectives develop.
