The USGS Texas Streamflow site has some shocking flow rates. The Colorado River at LaGrange, is at 83,400 cf/s and the Brazos has rates in excess of 60,000 cf/s. The flow rates earlier in the weekend were little, if any. I suppose this was due to the backup of flow from the ocean surge. It finally came down enough to allow flows. At any rate, I don't think we will do a kayak trip on the lower Colorado for a while.
