Rivers are a natural easement of public access.
Tyhank God for american law, in Europe the best rivers are selfishly owned by the lucky land owners, but here in the states water is publicly owned. Fishermen who like to wade and walk streams need to stand together on this. If landowners hasd their way no body would be able to fish in any stream. As for access in the Sycamore area, I used to live just outside dekalb and my advice is to travel slightly northwest to genoa or kingston. The river is teeming with smallmouths, walleyes, catfish, and pike.
