Full moon marks early-fall turn for Santee and Lake Murray
The full moon on September 27 lands right at the seasonal turn for Santee and Lake Murray, as cooling overnight air starts nudging both reservoirs out of summer's pattern. Crappie and baitfish typically begin sliding toward creek channels and standing timber this time of year as forage pulls off the flats, a shift that plays out across Southeastern reservoirs each fall.

Expect the transition to keep building over the next few days: shortening days and the bright full moon favor low-light feeding windows, so dawn and dusk should out-produce the midday hours through the weekend. If the cooling trend holds, look for crappie to keep pushing deeper into creek arms and around brush piles as baitfish concentrate there, and for surface activity to pick up in the first and last hour of daylight.
Plan around the moon's overnight illumination — fish may feed a bit later into the night and slower to turn on at first light as a result.
Context
This lines up with a normal early-fall calendar for SC reservoirs like Santee and Lake Murray, where the shift from summer to fall patterns usually shows up in late September as water begins to cool from the surface down. It's an on-schedule transition rather than an early or late one, and the pattern typically continues to develop through October as the thermocline breaks down and fish spread out to feed more aggressively.
