Long-term science. On-the-ground work.
UMOWA's projects are a tight loop: gather rigorous data, share it openly, then turn it into the restoration and stewardship work the river needs.

Macroinvertebrate Studies
EPT richness, biotic integrity, and the flushing-flow story — a decade of bug science.
Aquatic Plant Project
Mapping vegetation and bathymetry from Holter Dam down to Cascade.
Restoration & Stewardship
