Dear tearin up topwater, I've fished Buschs for about 30 years, first off lake 33 is your best chance to land the lunker bass, however october is typically not a especially good month to do so..best lunker months are April and May prespawn and spawn, and yes you need a boat to find the deep brushpiles.. another good lake in spring is Lake 35..bring your fishfinder...for as long as I can remember lake 7 is a predominantly a catfish lake, but there are a few very large bass in there..In the next couple of weeks as the water cools try a white buzzbait early in the am,then go to small bass jigs or 6 incch worms texas rig Good luck, mofishin
