Scientific Studies & River Reports
A decade of UMOWA-commissioned research — water quality, bug-life, vegetation, restoration, and more. Searchable, downloadable, and organized by program.
A decade of independent science.
Three programs — water quality, aquatic insects, and aquatic plants — anchor UMOWA's research on the Upper Missouri. Plus the live data and access tools that make the river usable today.
Water Quality
Annual nutrient, chemistry, and trend monitoring at the Craig transect since 2015.
Macroinvertebrates
EPT richness and biotic integrity — the gold-standard cold-water health index.
Aquatic Plants
Vegetation surveys and bathymetry from Holter Dam down to Cascade.
Flushing Flows
Why scouring flows matter — and what UMOWA's data has shown the agencies.
Live River Conditions
Multi-gauge dashboard with flow, temperature, weather, fishing read.
River Access Map
Public ramps, FAS sites, and walk-in spots from Holter to Cascade.
