Hi guys and gals. New to the forum. If most forums are anything like the current topic "Carolina Rigs", I'm glad I joined. I'm trying to expand my skills beyond being a "bank beater", to a more advanced fisherman. Anyway, my first questions are these: When you hear in bass instruction "when the water temp. reaches 66 degrees, the bass will begin moving to such and such", does that temperature hold true to anywhere in the country. My angle is this. I live in South louisiana so my water temps will get warmer faster than some fishing pro who may be talking water temps in tennessee. If lets say 66 degrees is the magic number for bass to move into the shallows in tennessee, is that the same magic number in louisiana, but it will just only happen sooner in the year. Also, when looking for structure in your boat using a depth finder, how deep does the water have to be when your passing over a ledge, that may be holding fish, to where your not spooking the fish with your boat?
