oh ya anything can be fished that depth really you know theres ways to do it, lighter more sensitive line or braid and so on, you can fish big football jigs or hula grubs that deep easily i have even fished small finesse worms on darterheads as light as 1/8oz in depths that deep and even greater, take into consideration these are largemouth were dealing with and really deep for largemouth in my book is 20' as a solid depth they really dont get too much deeper than than unless you have really steep banks the move up and down onn or intense heat or even cold im sure it depends on conditions with all bass fishing but i wouldnt go out there in those depths without graphing fish or some promising structure (not saying they dont) but largemouth especially the big ones will be where the bait is if its bluegill normally shallow, if its trout off of points or other protruding structure off of deep water waiting in ambush, you might try draggin a big carolina rig through there you can even fish a swimbait in that depth i will show you how to fish that depth for big bass its something i do quite frequently
