You can probably get good lake maps for all 3 at the WalMart in Grenada. For Enid and Sardis that pre-spawn can be hit or miss so you might have to move around some to find them. At Enid there is some standing timber in relatively deep water just out from the Water Valley ramp (easily found on a map) that usually holds some fish. Also, I don't fish the upper lake at Sardis that early but I hear people talking about Piney Point. I usually fish the lower lake at Sardis in March and find them in laydowns.
