Sam Rayburn is LOADED with black crappie in the .75-1.25lb range! Probably caught at least 100 fish each day. Heck, I even sent a buddy home with a 2 man limit on Friday from pre-fishing, and there were still lots of fish on that same structure the next day.
Most folks I talked to were catching their fish about 10-12' deep in various depths of water.
We caught most of our fish in 14-16' water suspended about 6-10' down on submerged timber and stumps. They wanted it on the fall, so we were pitching jigs out and letting them swing over the cover. The bite was very light, often just noticed the line going slack. Stumps, trees, BPs, etc., the pattern was pretty much the same. Our best 4-5 fish came off the same big stump.
1/8oz JERRRY'S JIGS in the Zorro color did well, and adding a small blade helped. Partner used some twister tail type plastics on a road runner head that did well too. No minnows during pre-fishing, but we did tip with a minnow some on tourney day to see if that picked up bigger fish. Didn't really notice any difference.
Big shout out to the folks at Shirley Creek Marina! They were very hospitable folks.
