If you can find some fairly clear water it will work. Depths of around 10 feet are required normally but can be fished shallower if you have to. On Rough if the weather has been steady and the water is not muddy it will work. Fish feed and mate in muddy water all the time. You might want to put some kind of small rattle or glass beads on it to improve the bite but I dont see a reason for the Float and Fly not to work. May even work well on crappie on that lake.
