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.

FAQ

About Castle Lake Trail #4w02 Siskiyou 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?

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?
