Funny you bring this up BK. I have had 11 Flatheads on Crawlers in the month of August. Of course, I have been fishing crawlers a lot more this year than most years in case one of those bottom suckers swims by. At least half of the fish have been over 25#’s with a couple pushing 40. All the while, the bullheads sit there swimming around and the cut bait gets hit on rare occasion. Keep in mind, this is all happening near fairly deep water. Put a crawler on in 15′ or less and commence freshwater drum cranking!
I forgot how much fun it was to take people up there, throw out a crawler and wait to see what happens. We have had some great days and lots of laughs. 25’+ water has produced: Shovelnose Sturgeon, Lake Sturgeon, Channel Cats, Flatheads, Mooneye, Walleyes, American eels, Drum, carp, smallmouth buffalo, Redhorse and a white bass that hit the bait while I was reeling in. You have got to love this river! All these fish have come on a “Gob” of crawlers.
