Great info guys. Just a little more info on the lake:
1. One place is pretty much featureless. its has a big contour change since its on a channel edge but as it goes back, its pretty shallow. no lay downs or cypress trees. It's a prime duck hole during the winter.
2. The other grass flat begins at a channel edge where the lake was dredged. The channel goes from 10-12 feet to the 4 foot flat. as you move up toward the bank, the depth nears 2 ft and the edge is matted hyaciths and stuff, which i usually punch. The flat has kinda patchy grass. A clump here and there mixed with pad stems in some spots. The flat has has a good many cypress trees which I've caught fish off of. However, I think that that the that the bigs ones shy away from the trees bc everyone hits them.
Once the grass matted last summer, I fished a frog and caught some pretty good ones, but once the sun came up, the top water bite died and the grass was too thick to swim a jig or swimbait. So I flipped around around little bit with no success and then punted and ran to the cypress trees.
