I think a lot of people think the lake is so shallow and dangerous, it isn’t that way at all. On the main body of the lake, where most of the panfishing is done, you will not dmage your motor. Sure the lake is shallow, but, there is a difinitive area that boaters use to navigate through the lake. When you find a place you want to fish, slow down and you can drive right to the area. We were fishing the other day in 22′ of water. The dredge channels are between 8-20 feet of water. Most of the panfishing is done on the weed beds, edges of weeds, and in the channels. In the spring and fall there is still unbelievable gill and crappie fishing. Summertime poses a challenge, but they are still in there. Please do not be afraid of Lake Onalaska.
