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 Dulles Avenue reads around 51 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 63.6 ft.

The bottom of the channel here sits at 51.0 ft, so the channel is roughly 12.6 ft deep at this crossing. City of Sugar Land publishes the top-of-bank figure with each reading; it is their reference, not an estimate made here.
