138.8 At levels above 138.8 feet major lowland flooding continues with water to the gage house on the left downstream bank. The approaches to the FM 1458 bridge are inundated and impassable. The home on the left upstream is likely flooded with several feet of water.
129.3 At levels above 129.3 major lowland flooding begins with the east approach to the FM 1458 bridge inundated and the home on the left upstream banks is likely flooded.
128.4 At levels above 128.4 feet moderate lowland flooding continues with water to the toe of the right downstream concrete bridge apron.
127.8 At levels above 127.8 feet moderate lowland flooding begins as water is over the gravel driveway on the left upstream bank threatening to isolate the homeowner.
