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.
River Insect Studies
Aquatic insect surveys — the gold-standard indicator of cold-water river health.
Aquatic Plants
Vegetation surveys and bathymetry from Holter Dam down to Cascade.
River Flows
Why scouring flushing 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.
