I know this is a little late on the response but it should still apply for Pratt Lake. If you look at your lake map you should see that the lake is almost split in half. There is a long point that comes down from the north right in the middle of the lake. Just off the southern edge of that point there is a fairly large island between the point and the south shore. To the east of that large island you will find two somewhat marshy islands. The south island is the key for me this time of year. Fish the east half of the lake directly east of the small southern island where the water drops from 10 - 15 fow rather abruptly. In that area there is a fairly quick change in the composition of the lake floor. Around that island is mostly sand to the east until you get into the 10 fow ish area, then it will suddenly change to a clay bottom and drop into 15 fow, that's where I find them quite often on warm sunny days and in the evenings. Other times I will just go a little farther east and search for them over the deeper water. The water directly east of that small southern island is the quickest drop of the entire lake and is near transitions of the lake bottom. Minnow will often be up on that sand this time of year so the specks are there as well, though they will usually be out toward that 15 fow. There are some weeds and wood structure on the bottom very near where the sand changes to clay so it is a natural holding area. Add to that the fact that it is the area that is easiest for those specks to get from relatively shallow water into the deepest hole in the lake and you have a crappie spot. I don't know if you have fished Pratt Lake at all but there are some real dandies in there. Hope this helps a bit. Good luck.
It is not about the equipment you have to use,
It is about how you use the equipment you have. :D
