Access and shuttle
Launch below downtown Watertown and take out at Jefferson County Rock River Park for a long upper-Rock water-trail day. The app uses the direct Watertown gauge as minimum-only because the route source gives a trip level, not a full threshold ladder.
Access map
Put-in
Willow Street / Front Street launch corridorStay below the Watertown dam corridor for this route. Starting above a dam or improvising a portage changes the hazard model.
Take-out
Rock River Park / County Road BWillow Street is a water-trail access with street-parking context rather than a full-service launch. Check current local signs and construction before unloading.
Road shuttle
Stage Rock River Park first, verify the park and launch are open, then drive back to the Willow Street / Front Street launch corridor below the Watertown dam. This is a long rural shuttle and should start early.
Additional access notes
- Rock River Park can close during flooding, and Jefferson County notes boat-launch permit requirements. Confirm take-out access before launch.
More route and safety guidance
- This is a 16.75-mile day. Wind, fatigue, motorboat wakes, shallow bars, and bridge current can turn an easy-looking river into a long shuttle problem.
- Jefferson County warns Rock River Park can close during flooding. Verify the take-out and any boat-launch permit requirement before launching.
