And before this turns into yet another shallow-fishing bashfest, I have a couple of things to say.
One is that there are pretty much always some fish shallow. Yes, even on the White River lakes. My wonderful dad introduced me to fishing and I love him beyond words for it, but my biggest influence in learning the finer points of bass fishing is a guy with three world championship rings (two Bassmasters Classics and a Forrest Wood Cup). He also happened to be best man in mine and Donna's wedding nearly 23 years ago. This guy couldn't feed his family a decent meal with ALL the fish he's caught deeper than 15 feet in his life.
Where people err badly is when they group every shallow water fisherman they come across into a single group of unintelligent bank beaters. Yeah, there are a lot of those out there. Believe me, I see them all the time. Usually catching nothing and just messing up good water.
A good shallow water angler has to be a lot of things --- perhaps the most important on big highlands reservoirs being able to read the water and recognize where fish are gonna be holding. You need shade and/or wind, along with forage and cover. And more times than not these days, cover doesn't come in the form of wood. Our lakes are aging and the wood is getting sparse. Moreover, what's left gets beat to death.
There's so, So, SO much more to shallow fishing than just the little bit I've mentioned here. Just don't automatically assume that every guy you see fishing skinny water is a shallow-minded bank beater.
