I've not personally fished in that lake. But according to Pete Healy, in his book "Oregon Coast Fishing Maps" comes this excerpt...
"Most of the fishing pressure is directed at the trout and Sutton has a surprising number, of native and carryover rainbows that will measure more than 15-inches in length." But Pete also notes that, most of the trout average 12-13 inches.
He also states, in the same book, that...
"Both still fishing with bait, and trolling flasher and bait combinations work well...."
In addition...
"Bass weighing more than 6 pounds are pulled from Sutton every year."
If you go, let us know how you do.
