Access plan
Access, shuttle, and map
Launch below the Otranto dam and paddle the upper Cedar River to Acorn Park. This is a source-backed Mitchell County access pair, but the broken-dam finish and stale Osage gauge require conservative same-day judgment.
Put-in
Otranto Park below-dam accessOpen mapOtranto launch discipline matters: put in below the dam only and stay out of dam hydraulics.
Take-out
Acorn ParkOpen mapThe guide says the Acorn broken dam may be runnable for experienced paddlers after scouting, but also warns it is fast water with little margin for error and old metal can be exposed at low water. Treat Acorn as the planned take-out/portage boundary.

Access caveats and watch for
Access caveats
- Otranto launch discipline matters: put in below the dam only and stay out of dam hydraulics.
- The guide says the Acorn broken dam may be runnable for experienced paddlers after scouting, but also warns it is fast water with little margin for error and old metal can be exposed at low water. Treat Acorn as the planned take-out/portage boundary.
- USGS 05457505 at Osage returned stale 2017 Water Services data during this run, so the app uses downstream USGS 05457700 at Charles City plus a required visual check at Otranto.
Watch for
- Broken-dam current, exposed metal or rock at low water, old dumpsite debris, and shallow riffles.
- Strainers, outside-bend wood, private banks, agricultural runoff after storms, and limited mid-route exits.
- Fast rises after rain, cold shoulder-season water, and the consequence of missing the Acorn boundary.
