Safety
Route safety
Advanced routeThis route has hazards that can create serious consequences if missed or misjudged. Paddle only with appropriate skill, equipment, and current local information.
Safety details
American Whitewater supplies approximately 1.25 ft low-runnable context for the nearby Middle Potomac reach; use it only as a conservative planning screen and recheck USGS 01638500 trend, local water, wind, and debris. NWS/MARFC identifies 2.0 ft caution and 5.5 ft danger for boaters at Point of Rocks.
- Violettes Lock is adjacent to Dam No. 2/diversion works. Take out upstream at the named Violettes ramp; never drift toward, run, or improvise a landing around the dam, canal feeder, or downstream Great Falls reach.
- The Potomac is broad and moving with limited legal shore exits. Wear a fitted PFD, stay clear of private or opposite-bank property, and treat Sycamore and Rileys as conditional access—not guaranteed rescue points—unless current carry and landing conditions are confirmed.

- Violettes is a small-vessel gravel/soft-launch setting with a diversion dam at the canal entrance; it is an upstream hard take-out, not a continuation point.
- The Point of Rocks gauge is upstream and direct for the river, but it cannot certify local water depth, dam hydraulics, wind, or landing safety.
Watch for
- USGS 01638500 stage, discharge, and trend
- American Whitewater 1.25 ft low-runnable context, NWS 2.0 ft caution/5.5 ft danger screens, fast rise, wind, cold water, floating wood, strainers, and private banks
- Sycamore/Rileys bailout carries, Violettes gravel access, Dam No. 2/diversion works, Great Falls boundary, parking, and daylight

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named moving-water corridorEdwards Ferry to Violettes Lock, approximately 8.7 Potomac river miles
The NPS/C&O guide and Trust ramp inventory identify the endpoint chain and the route remains bounded above Dam No. 2.
- Authoritative public accessEdwards Ferry, Sycamore Landing, Rileys/Seneca, and Violettes C&O/NPS ramps
The C&O Canal Trust documents the named public ramps, canal miles, parking/carry context, and coordinates; Maryland DNR identifies Violettes as non-motorized access and warns of the diversion dam.
- Direct flow evidenceUSGS 01638500 Point of Rocks plus NWS/MARFC boating stages
The gauge is direct same-river route context; the NWS 2.0/5.5 ft stages and American Whitewater 1.25 ft nearby low-runnable value are conservative screens, not depth guarantees.
- Dam boundaryViolettes/Dam No. 2 is a mandatory upstream take-out boundary
Maryland DNR and NPS materials identify the diversion/dam setting; do not continue toward the structure or Great Falls.
- Camping postureNearby C&O hiker-biker camping; no route camping
Horsepen Branch is a separate campsite near the corridor, not a promised river landing or overnight bank.
- Live gaugeUSGS 01638500, Potomac River at Point of Rocks, MD
This is a direct same-river station. Readings are provisional and must be combined with trend and visual conditions.
