I am only on my second year of blue cat fishing the Missouri river. I know big blues are caught above rock dykes in the flats at night. My question is where exactly above the dyke is the best location to anchor boat? How far from dyke? how far away from bank? what are the best depths at night? I fished a tournament last saturday night there was a 81LB blue weighed, 67LB blue, 58LB blue, and several blues over 20lbs. All i could catch was small fish. I had cut shad, cut bluegill, and for flatties had goldfish and creek chubs. But i mainly fished for blues just because these tourneys i have been fishing in are all won with big blues. Any comments and/or help would be greatly appreciated. My 2 big blues last year were 17LBS and 28LBS. I want the 50lb or bigger and i know they are in there!!!!
