When the Brazos is normal, it is about 1 foot deep flowing across the flat. There is an island and the water mostly channels to the east bank in a concentrated stream about 3 foot deep at that locale. It is really swift in that narrow stream. It then slows across a pool about 8 foot deep that runs about 50 yards.
If you cast anything light out in the swift part and let it flow into the pool, you just need to hold back a little tension. You'll catch a lot of sand bass but you also reel in bream, crappie, black bass and an occasional striper. I like the little sand bass rubber jigs. Big tackle doesn't net the sand bass or bream like the little tackle does.
For stock tank (man made ponds for you northern folk) bream fishing, worms are great.
Had a bug light out over the lake once. My nephews were about 6 and 8 years old at the time. We tied flies on string on a pole and they flicked it out all night long. I just sat there in a lawn chair taking fish off of their lines and letting them catch more. They are in their 30's now and they still talk about that night.
