Ottawa to Starved Rock state park and back is a fun 16 mile trip. It can be done in one day, but with upstream for half the time, it better works as a short overnight trip. It takes about 3 hours to go all the dam, then 5 to get back.
The water level was low this round, and the islands/grasswere high and overgrown. The low water level meant reduced current, so it was easy getting back. Camping was problematic with the high grass. Sheehan Island, which is normally a gold mine for camping, was inaccessible from the back due to the low water levels. The front was overgrown with waist high grass, so we moved back upstream for a campsite.
