It's my thoughts on slick water is sound and shadows. It seems that fish of all species are a lot spookier when there isn't a ripple or wave action on the surface. Take the baitfish for instance. On slick water when you make a movement they scatter while with a ripple or light waves they do not. Then comes the sound part of it. With slick water just the slightest sound will spook the fish. Again try the same thing with and I am sure you have noticed this many times before that they will spook and scatter with the slightest sound. Just my theory and I am sticking to it. I can tell you that clear water fish are different animals. I almost never run over a known pile with my big motor. Always with my trolling motor. Reason being spooked fish. I have put this theory to the test many times on clear water fish and it produces many more strikes and fish in the LW by doing it this way........Ranger
