Well I decided to try Lake Hartwell this afternoon...we couldn't find any slab crappie like I've been on, but we found the perch...wish I woulda took a picture of the graph

..blacked out 3' off the bottom

...caught 'em between 16'-21' deep on the bottom....w/ black/chart alibi jigs, live bait and jigging spoons...between 2:00pm & 4:00pm it was on...we caught well over 100 perch, I'll get a better count when I clean 'em and try to post a pic tomorrow night. Fished the Tugaloo arm, water was slightly stained, water temp was 62. Guess I'll try the slab hole next weekend.
