Welcome aboard Matth . Lake Onalaska is a huge body of water for sure, with lots of places to try. You said you were familiar w/Fisherman’s road area…That back bay at the end of the road is always an area favorite and definately one of m own . It averages 3-5 feet throughout that bay w/a deep channel off towards the other side of the bay…That channel runs all the way down towards the spillway. If you ever been back their during the summer….it’s VERY easy to see the layout of that bay area…both weed wise and depth wise. So if you’re gonna setup back there…try any where off the West bank…I saw some crappie their last week, but couldn’t get any takers however, i was taking some monster ‘gills …..if that isn’t working, go ahead and try that deeper channel…as they could be suspended out that way. I’m not sure what kind of gear you have (vexilar/Aqua-Vue), but that always helps as well..(i don’t have any of it either )
You can also travel up by Brice Praire area and try all the way through there. In my opinion, your best bet there is to get a Map of lake Onalaksa that shows the depths of that area because that entire region for the most part has all been dredged out…So the depth can range anywhere from 2ft to about 30ft or so. On any given day, you’ll see a plethera of people fishing the shallower surrounding bay/weedy areas, and you can also see them fishing the dredges..Once again..i’d stop and go until you found crappies …Once you’re onto them, as Watson will tell you–the bite will be good.
As for bait…If you read further up, i think Watson has a update on the lake from this weekend, but jigs/waxies work….and since you’re looking for crappie, obviously minnows will be an option.
If you’re out and about..Look for me…I’m usually in my Clam2000…but come outside to stretch and see how everyone else is outdoing me ….
