How to read this gauge
The number above is an elevation, not a water depth. It is the height of the water surface above a fixed reference level, so SH 36 reads around 69 ft even when the channel is low. What matters is the distance to the top of bank: the elevation at which water reaches the top of the channel at this location. For this gauge that is 72.5 ft.
The bottom of the channel here sits at 67.8 ft, so the channel is roughly 4.7 ft deep at this crossing. Fort Bend County publishes the top-of-bank figure with each reading; it is their reference, not an estimate made here.
