Safety details

Gauge note
Minimum 350 cfs · Fox River at Princeton, WI
Gauge context
Use the Fox River at Princeton gauge. WRT ran this at 820 cfs and calls it relatively low, but suggests skipping the reach at 1000 cfs and up; Paddle Today uses 350 cfs as a conservative low-water floor and withholds an ideal range.

Route logistics
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 caveats and watch for
Access caveats
- Princeton 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.
- The 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.
- 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.
Watch for
- Low-head dam and electric fish-barrier hazards at the put-in area.
- Wind on the broad Upper Fox, slow current, dirty high water, and floating debris after rain.
- Private shoreline, bridge approaches, fishing lines, and limited legal exits between endpoints.

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.
- Current gauge check520 cfs / 3.88 ft at 2026-07-22 16:00 CDT
USGS Water Services returned a current direct Princeton reading above the selected conservative floor during this run.
