Fox RiverPrinceton Lock and Dam to Princeton City Landing
Short Upper Fox town-and-woods segment from the DNR Princeton Lock and Dam landing below the low-head dam to Princeton / Hiestand Park. It is a quick public-access link with a direct Princeton gauge and a mandatory below-dam launch decision.

Permits, camping and season
Access and shuttle
Launch below Princeton Lock and Dam and paddle north to the city landing in Princeton for a short Upper Fox route. The direct Princeton gauge is useful, but the dam-adjacent start and wind exposure deserve same-day checks.
Access map
Put-in
Princeton Lock and Dam / Lock Road landingPrinceton Lock and Dam has a dangerous low-head dam and electric fish barrier. Launch below the structure and do not approach it from upstream or downstream.
Take-out
Princeton Jefferson Street / Hiestand Park LandingThe Lock Road side has DNR public boat launches, parking, and seasonal restroom support; the Oxbow Trail side is not the normal boat-launch side for this card.
Road shuttle
Stage the Hiestand Park / Jefferson Street city landing first, then return to Princeton Lock and Dam on Lock Road. Confirm you are launching below the dam and fish-barrier area, not above it.
Additional access notes
- The city landing is the planned take-out. Downtown events, fishing use, or local parking rules can affect staging.
- The route uses minimum-only scoring because WRT gives a low-water/high-water heuristic rather than a formal two-sided paddling ladder.
More route and safety guidance
- The route is short and slow, but the open Upper Fox can become unpleasant in wind or high, dirty water.
- Use the named public landings only; private banks and shoreline yards are not assumed legal stops.

NotesPublished evidence and verification notes
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Route-specific guide3.58 miles; public ramp to public ramp
Wisconsin River Trips documents Princeton Locks public ramp to City of Princeton public ramp, with distance, shuttle, dam, wind, and level notes.
- Dam safetyLaunch below the dam/fish barrier
WRT warns of a dangerous low-head dam and electric fish barrier at the put-in; DNR identifies the Lock Road site as the boat-launch side of Princeton Lock and Dam.
- Direct gaugeUSGS 04073365 at Princeton
USGS locates the Fox River at Princeton gauge on the same town corridor, and WRT ties the route to this gauge.
- Conservative floor350 cfs minimum-only
WRT says 350 cfs may be the yearly low, that 820 cfs was relatively low, and suggests avoiding 1000 cfs and up. The app uses only the low-water floor and does not infer an ideal range.
