-- -- Loading --
Difficulty moderate The run is short and mostly Class I at normal levels, but the accesses are undeveloped, the current stays swift, and higher water makes the narrow bends and bridge-area landings less forgiving.
Permits None noted No route-specific paddling permit is known. Follow Jackson County water-trail signs, posted road-right-of-way rules, and Ozark Wildlife Area restrictions.
Camping Options nearby Do not assume legal river camping on this short route. Jackson County lists primitive camping for some water-trail contexts, but site permission and land ownership should be confirmed separately before planning an overnight.
Season Apr-Oct Spring and fall are the best scenery windows because leaf-off conditions expose more cliffs and boulders. Heavy rain can quickly make the North Fork pushy and turbid, while dry late-summer periods can make riffles too shallow.

Access, shuttle, and map

Launch from the Ozark Bridge / 21st Ave access area near 185th Street and take out at the east-bank Caven Bridge Access on 60th Ave. This short Ozark Wildlife Area route has fast current, easy riffles, boulders, and steep Driftless bluffs.

Start

Put-in

Ozark Bridge / 21st Ave access area Open map

Ozark Bridge is an undeveloped access rather than a managed ramp. Jackson County marks it as not managed by JCCB, and WRT describes using a public pull-off and faint trail near 185th Street instead of the tall bridge bank.

Finish

Take-out

Caven Bridge Access / 60th Ave Open map

Caven Bridge Access is the named public take-out at 60th Ave, but the bridge has been removed. Use the east-bank public side; WRT notes the west bank is private and requires permission.

Pulling access map tiles. Usually under 5 seconds.

Access caveats

  • Ozark Bridge is an undeveloped access rather than a managed ramp. Jackson County marks it as not managed by JCCB, and WRT describes using a public pull-off and faint trail near 185th Street instead of the tall bridge bank.
  • Caven Bridge Access is the named public take-out at 60th Ave, but the bridge has been removed. Use the east-bank public side; WRT notes the west bank is private and requires permission.
  • Coordinates come from Jackson County water-trail table coordinates rounded to two decimals. Use road names, signs, and same-day scouting to pinpoint the practical launch and carry-out paths.

Watch for

  • Swift current and light Class I riffles immediately downstream of the put-in that become pushier above the target range.
  • Muddy undeveloped banks at both ends, plus steep bridge-area approaches and limited roadside maneuvering on gravel roads.
  • Cold shoulder-season water, fast rises after heavy rain, and private-property boundaries around road-right-of-way and west-bank access.

  • Target range 231 to 400 cfs

    WRT treats 231 to 300 cfs as average and good for paddling, and 301 to 400 cfs as above average but still good, using the North Fork Maquoketa River near Fulton gauge.

  • Low and high cutoffs <150 cfs / 701+ cfs

    The same route ladder says less than 150 cfs may be too shallow and 701 to 1000 cfs is very high, perhaps only suitable for advanced paddlers; the app uses 701+ cfs as the broad recreational high-water cutoff.
