Thanks for the info guys. The information I had was incorrect in they said there was NO pay station at Jordan but that was incorrect, as stated above you can pay the $7 fee and launch. Launching went fine but I quickly realized I didn't have a clue where it was safe to run so just stuck fairly close to the launch to fish and crapped out. Wind picked up, lake got choppy so had to just jump on plane and go for it back to the launch. Guess I need toi hire a guide and learn the basics of safely navigating this lake....
Running the main body of Roberts is easy. South of the big island on the east side (Wolf) all the way around to the bridge on the west, you're good. You can run into Isle du Bois around by the dam, Johnson, Pond and Spring creeks all just fine. Once you hit a set of marker poles, idle. Look out for long shallow points on your graph in the main lake, but you have lots of fishable water near this open water stuff.
There is good fishing up amongst the timber, so if you want to explore, idle and mark sections of trail, but be extremely careful of changing water levels and stay right on your trails as you can get BAD in a hurry!
