Welcome to the Siuslaw Watershed Council !

The Siuslaw Watershed Council, a 501(c)(3) non-profit organization, provides an opportunity for local people to plan and participate in the restoration of their watershed.

Watershed councils are volunteer driven organizations that develop and participate in community efforts to restore and protect watershed health, water quality and native fish populations. Every council is unique, and each council reflects the interests and land ownership patterns in their watershed. Councils are not governmental organizations and are not regulatory.

Anyone can participate in the Council! We help landowners fund and carry out protection and restoration efforts on their land. We form partnerships with industries and agencies to implement important research and restoration efforts. We provide educational opportunities for the Council and the community. If you are interested in watershed health, get involved! COUNCIL MEMBERS MAKE IT HAPPEN!

General Meeting Wednesday, June 28, 6:30 – 8:30 PM

Blachly Grange, Blachly Grange Rd. near the Triangel Lake School campus. Doors open at 6:00 PM

"Hult Reservoir and Dam Safety Study" and "Effects of Experimental Removal of Barred Owls on Population Demography of Northern Spotted Owls in Washington and Oregon."


Hult Pond_1Cheryl Adcock, Field Manager for the BLM Siuslaw Field Office, will present on Hult reservoir (sometimes called Horton Mill Pond) that was developed in the early 1900’s for logging operations. The reservoir is within Upper Lake Creek above Triangle Lake and located about 5 miles north of Horton. The reservoir and associated wetlands is 40 acres in size that supports a variety of fish, wildlife and wetland plants. The site is also used for recreation. With dam safety in mind, BLM is preparing an Environmental Impact Statement (EIS) for the purpose of ensuring a safe environment downstream from the dam. BLM will also look at the effects the dam and reservoir have on recreation, sensitive wetlands plants, listed fish, revenue to local communities and cultural and historic values.


Barred_Owl_DSSpotted_Owl_DSDave Simon, USGS Research Wildlife Biologist will present on the removal of Barred owls. Evidence indicates that competition with invasive barred owls (Strix varia) is causing rapid declines in populations of northern spotted owls (Strix occidentalis caurina), and that the long-term persistence of spotted owls may be in question without additional management intervention. A pilot study in California showed that removal of barred owls in combination with habitat conservation may be able to slow or even reverse population declines of spotted owls at local scales, but it remains unknown whether similar results can be obtained in areas that have different forest conditions and a greater density of barred owls. In 2015, we implemented a before-after-control-impact (BACI) experimental design on three study areas in Oregon and Washington with at least 20 years of pre-treatment demographic data on spotted owls to determine if removal of barred owls can improve localized population trend of spotted owls.



There will also be an Board of Director and Executive Director updates on various SWC projects.
