Low Water Records

Graphical representation of flood inundation for NWS flood categories are based on steady state hydraulic modeling of water surface elevations for incremented discharges. Map shows approximate inundation areas for given water surface elevations and should not be used for navigation or permitting or other legal purposes, but strictly as a planning reference tool.

Extended rating:
Rating Curve Extension - The Rating Curve Extension is calculated by using either a linear, logarithmic, or hydraulic technique to extend the rating curve above the currently established relationship between stage and flow.

34 This is the flood of record, which caused massive lowland flooding
28 Major flooding approaches the river levees near the San Antonio river confluence. Miles of Highway 35 and the flood plain near it flood, cutting off many homes and flooding a fishing camp near Tivoli. Hundreds of livestock are cut off and potentially drown
27.5 Major flooding occurs, isolating livestock. The river floods equipment and livestock in the flood plain and can flood residences downstream near Tivoli. Highway 35 east of Tivoli floods
27 Major flooding occurs. Flow downstream near Highway 35 is several hundred yards wide, cutting off many of the lowest homes. Livestock are cut off and could drown. Pumps, tank batteries, and any equipment in the flood plain below Victoria are flooded. The campground near Tivoli below Highway 35 and residences just above Highway 35 are flooded
26 Irrigation and oil well pumps, tank batteries, and equipment in the lower flood plain below Victoria flood. Livestock are cut off, may have to be fed by boat, and could drown. Homes downstream above Highway 35 on the left bank are cut off
24 Moderate lowland flooding occurs, with the river reaching well into the flood plain. Any oil tank batteries, pump jacks, and secondary roads near the river may be flooded
20 Minor lowland flooding occurs, with the flow reaching the right flood plain near the Invista Plant near Bloomington. Downstream above Highway 35, the flow escapes into the left flood plain cutting off the lowest homes
