On the East fork of Hubbard past 66, you can find water to 20 foot or so. As shallow as 8-10 on some hump areas.
Decent fishing in some places up there around the trees. Watch out though, a LOT of trees have broken off at, or just below, the water line and are now a pretty good hazard.
The west fork of Hubbard past 66 has a max depth of around 8 feet . Same stump hazard issues there as well.
The horsepower of one's outboard, should never exceed one's IQ.
Therefore, I'm the proud owner of a 60HP Merc!
