The most important thing to the ecosystem is the purity of its lifeblood, the water. YDWP has been a part of the MiCorps Volunteer Stream Monitoring Program (VSMP) for the Yellow Dog River since 2004, and in 2013 we started a VSMP for the Salmon-Trout River. The VSMP program incorporates: volunteer participation, stream habitat assessment, macroinvertebrate collection, and a stream quality score. The program runs twice a year for both river systems, and we are always looking for interested volunteers. No special skills or prior knowledge necessary. Our staff will be delighted to train you!
