CautionThis route has hazards or access considerations that require extra verification.
Safety details
American Whitewater identifies approximately 1.25 ft as low-runnable context and warns that shallow submerged rocks and changing channels can affect the trip. Treat that value as a conservative planning screen, not a promise of depth; recent rain, fast rise, debris, wind, or a falling trend can override it.
- Nolands Ferry is an intermediate bailout, not an automatic landing: American Whitewater notes the left-channel approach and downstream-angled ramp can be easy to miss. Scout the take-out early and preserve daylight for the Monocacy Aqueduct landing.
- Wear a fitted PFD and keep a cold-water margin. Stay off private or opposite-bank property, do not use the Indian Flats campsite as an assumed boat landing, and do not continue into the Monocacy River without a separate current route review.

Put-in
Point of Rocks Boat RampPoint of Rocks, Nolands Ferry, and Monocacy Aqueduct are public C&O/NPS boat ramps, but current flood, road, parking, railroad, carry, channel, and water-entry conditions control on launch day.
Take-out
Monocacy Aqueduct Boat Ramp / Mouth of MonocacyNolands Ferry is a hard optional take-out if the group cannot safely commit to the Monocacy Aqueduct; a missed landing can extend the trip into a separate and unreviewed reach.

- Authoritative public accessPoint of Rocks, Nolands Ferry, and Monocacy Aqueduct public C&O/NPS boat ramps
NPS and the C&O Canal Trust document the endpoint and intermediate ramps, canal miles, parking, and Potomac access. Coordinates are near-water anchors requiring current field verification.
- Direct flow evidenceUSGS 01638500 Point of Rocks with American Whitewater 1.25 ft low-runnable context
The station is at the upstream endpoint and supplies direct route-context stage/trend evidence; local channel, depth, wind, debris, and landing conditions remain controlling.
- Intermediate bailoutNolands Ferry at approximately 3.8 river miles
American Whitewater documents the intermediate ramp and the left-channel/downstream-angled take-out approach; scout it before committing to the Monocacy end.
- Camping postureNearby C&O hiker-biker camping; no route camping
Calico Rocks and Indian Flats are separate campsites near the corridor and do not imply water landings or drive-to access.
