Capstone Field Trip: A Tour of the "Alsea Revisited" Watershed Study Area

Thursday, May 31, 2012
9:00 am to 3:00 pm
Flynn Creek and Needle Branch watersheds

This field trip to the Flynn Creek and Needle Branch watersheds of the Alsea Revisited Watershed Study featured discussions on current paired watershed studies.  

A few images from the tour are viewable here.

The original Alsea Watershed Study (1959 through 1973) assessed the effects of timber harvesting on water, aquatic habitat, and fish resources using a paired watershed approach.  That study was a catalyst for the adoption of the Oregon Forest Practices Act (OFPA) and strongly influenced the specific OFPA rules.  The Alsea Watershed Study Revisited returns to the same watershed more than 40 years later to measure and compare the impacts of contemporary forest practices under the Oregon Forest Practices Act rules with those observed in the original study. The Alsea Revisited Study is investigating the effects of modern timber harvesting on hydrology; water quality including: sediment, stream temperature, dissolved oxygen, and nutrients; aquatic habitat; fish; and macroinvertebrates.
