I don't know if this will work in Texas but this is what is working on northern Indiana lakes. Weighted flies size 10 and 12 fished on 14' - 16' of level 2# fluorocarbon leader (or all you can cast) fished in 6' - 15' of water while the boat is anchored in 20' - 25' of water. Fishing the deep side weedy breaks on the north or east side of the lakes so the sun can warm the water a bit. Our water is in the mid to high thirties now but after this week we are probably looking at mid to low thirties. Fish slow with short strips.. Be watchful for fish taking the fly while it is falling. These will be very light bites. This works until ice-up when you can no longer use a boat.

Good luck,
