Dewey lake is listed to be great right now by game and fish. It has mussell infestation and that has cleared the water up and let the grass really grow. Some people have caught some really big fish in the last couple of years. Fish the grass, most rock and wood has so many mussells on them that it just breaks you off. Fish should be schooled on grass lines and hitting topwaters early and late and big worms in the daytime. As for pressure it depends on how fast the grass grows. For some reason when it starts to top out not as many people fish it. School will still be in and unless it is very warm it should not be to bad.
Happy Hooksets,
