I 90 Mineral County boat launch
I 90 Mineral County
According to the Montana Fish, Wildlife & Parks website, the Clark Fork River is open to motorized and non-motorized watercraft, including boats and kayaks. However, there are certain restrictions on the use of motorized watercraft, depending on the section of the river, to protect wildlife and habitat.
Overall, the I-90 Mineral County boat ramp appears to be a well-maintained and accessible facility that provides boaters with easy access to a scenic and popular waterway in Montana.

Boating safety & etiquette
- Check the conditions before you launch
- Use the streamflow numbers, weather, and wind forecast on this page. High-cfs whitewater requires whitewater-specific craft and skill.
- Wear your life jacket
- Statistically the single biggest survival factor in a boating incident. State law often requires one per passenger.
- File a float plan
- Tell someone on shore your put-in, take-out, and expected return time. Especially for multi-day or remote trips.
- Yield at the ramp
- Prep gear in the parking lot, not on the ramp. Launch and clear quickly so others can use the lane.
- Clean, drain, dry
- Inspect, clean, drain and dry your boat between waters to prevent the spread of aquatic invasive species.
Set push alerts in the Snoflo app
Save I 90 Mineral County as a favorite, set a discharge threshold or a wind/precipitation alert, and the iOS app will push the moment conditions cross.
About I 90 Mineral County
Can I launch a motorboat here?
Most Snoflo-tracked launches support motorboats; check the operator for any horsepower restrictions, paddle-only zones, or seasonal closures.
How fresh is the streamflow data?
USGS streamgauges report continuously (every 15 minutes); the table on this page pulls the latest reading at page load.
Is there a fee?
Many federal and state boat launches charge a day-use fee. Check the operator's site before driving out.
What boat is right for these conditions?
Use the nearby streamflow numbers and river-run panel on this page to gauge current conditions. Wider, slower water is friendly for casual paddling and powerboats; high-cfs whitewater requires whitewater-specific craft and skill.
Can I get alerts when conditions change?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this launch, set a threshold (discharge, wind), and you'll get a push the moment it crosses.
