DifficultyeasyThe mileage is short and mostly flatwater, but the dam-tailwater launch, release changes, urban bridges, and cold or debris-laden water justify a caution profile.
PermitsNone notedNo route-specific paddling permit is known. Tailwater East may require Corps day-use or camping fees; follow USACE postings, Iowa City park rules, and Iowa boating/PFD requirements.
CampingOptions nearbyTailwater East Campground has campsites, restrooms, showers, and the boat ramp near the put-in. Treat the Sturgis Ferry finish as day-use; do not assume on-route camping.
SeasonApr-OctCanWePaddle lists April through October as the normal season for the dam-to-Iowa-City reach. Reservoir releases can matter more than local rain timing.

Use this section once the route looks viable and you need to turn it into an actual trip plan.

Access, shuttle, and map

Launch at the public Corps ramp below Coralville Dam and take out at Sturgis Ferry Park before the longer Johnson County water-trail segment. Keep this framed as a below-dam connector with release checks and a firm downstream take-out.

Start

Put-in

Tailwater East public boat ramp below Coralville DamOpen map

Do not launch above the dam or paddle upstream toward the dam tailwater. Use only the public ramp below the dam.

Finish

Take-out

Sturgis Ferry Park boat rampOpen map

USACE recreation status lists the Tailwater East public boat ramp open but notes no courtesy dock; expect a practical ramp launch rather than a dock launch.

Pulling access map tiles. Usually under 5 seconds.

Access caveats and watch for

Access caveats

  • Do not launch above the dam or paddle upstream toward the dam tailwater. Use only the public ramp below the dam.
  • USACE recreation status lists the Tailwater East public boat ramp open but notes no courtesy dock; expect a practical ramp launch rather than a dock launch.
  • Sturgis Ferry is a city park boat-ramp take-out; orient inside the park because the saved point is an access-area anchor.

Watch for

  • Changing dam releases, cold water, debris, and stronger current after rain or reservoir operations.
  • Urban bridges and developed river edges approaching Iowa City.
  • Missing Sturgis Ferry and unintentionally continuing into the longer Sturgis-to-Hills segment.
