- Abstract: The South Santiam River drains approximately 1,040 square miles and is a primary tributary
to the Willamette River. The South Santiam River watershed is situated in the Western Cascades
and flows into the Willamette Valley. The River runs approximately from east to west, with
steep mountainous terrain comprising the eastern 80% of the watershed. The western 20% of the
watershed leading to the Santiam River and ultimately the Willamette River, is comprised of a
floodplain dominated by grass seed farming and urban/rural development. The basin ranges in
elevation from 220 feet to approximately 5,721 feet.
The South Santiam watershed was divided into an upper section (Headwaters, Quartzville,
Middle Santiam and Foster watersheds) and a lower section (Lower South Santiam, Crabtree,
Thomas, and Wiley subwatersheds) due to ecological differences such as ecoregion,
management, and elevation.
The assessment was conducted in six parts including Channel Habitat Typing, Channel
Modification, Riparian, Water Use and Hydrology, Fisheries, and Water Quality. Following is a
summary of results from each of the sections.
- Purpose: The purpose of this watershed assessment is to evaluate the current conditions of the South
Santiam Watershed and to provide recommendations that address the issues of water quality,
fisheries and fish habitat, and watershed hydrology. This assessment was conducted following
the guidelines outlined in the draft Governor’s Watershed Enhancement Board (GWEB)
watershed assessment manual (Oregon Watershed Assessment Manual (OWAM)).
