The boat ramp services the Missouri River, which is one of the most significant waterways in the state and is a popular destination for boaters, anglers, and other water enthusiasts. The Missouri River stretches for more than 2,300 miles, and it flows through seven states, including Missouri.
According to the latest information available, the Katy Trail Saint Charles boat ramp is open to the public year-round, and it is free to use. However, visitors should be aware that the ramp may be closed during periods of high water or flooding, and they should always check local weather and river conditions before heading out on the water.
In terms of permitted craft, the Katy Trail Saint Charles boat ramp is designed to accommodate smaller watercraft such as kayaks, canoes, and small fishing boats. However, visitors should be aware that there are strict regulations regarding the use of motorized watercraft on the Missouri River, and they should always check local regulations before launching their watercraft.

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 Katy Trail Saint Charles
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?
