Hey Redge, no one really knows for sure why the schools make a huge push to the shallows the three days of the the full moon or the new moon phases. Temps play a huge role when the water temps reach 50-58. The fish start staging, eatin everything in sight. This is because the shad go to the shallows along with perch, darters, and other juvenile fish. The spawn peaks on the last moon phase when temps are round 75 degrees. But also keep in mind how many crappie are in a lake, especially lake Eufaula, and how many areas fish differently! I have caught them spawning from the first week in March all the way to the second week in June. There are always huge fish caught on the moon phases though! Remeber they go to the bank in steps, a little shallower at a time! EB
