That fellow would be me!
After some serious thought, and a couple trips to Marburg, it might not be a good idea to float tube a big, deep, fishless lake like Marburg.
It is a beautiful lake, and wonderful for boating, but the fishing is poor.
I was happy to catch some tiny fish near the shoreline with a 1wt rod. The biggest bass I have caught there was a 12"er. That's OK for me, I like the action. A 12" largemouth is twice the size of the wild trout I usually catch.
It is very easy wading at any place in the huge lake. With chest waders on you can stand in four feet of water and be comfy catchin' the tiny fish. I had to downsize to size 16 to catch anything! Even a size 14 nymph was too big for the fish to hit.
95% of the fish are 3" sunfish, or 4" largemouth bass.
Still fun for me when the trout are gone and the Susky is turning into a smelly cesspool.
All day long there are a hundred boats drifting live minnows or live nightcrawlers on a float or bottom rig. Nobody catches anything! LOL And every ten feet of shore access, there is a bait spinner guy with a "not so bright look" on his face.
After seeing this, I didn't rush out and purchase a float tube.
I guess you like some fishing action, just like I do.
Pinchot has weeds along the shoreline, and a canoe might be better than a float tube. I see some sunfish there, but I also see snapping turtles and snakes. This is a mud bottom, shallow lake. If you float tube to a good spot, you will kick yourself silly to get back to your car!!
But, keep looking. Maybe a private farm pond would be wonderful for a tube?
I'm doing the same thing. If I can't find a good lake, I will fish the heck out of the carp in the Susky Cesspool!
