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.

About Merwin Hatchery Court, Ariel
Can I launch a motorboat here?

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?
