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 Greatwood Parkway reads around 52 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 69.2 ft.

The bottom of the channel here sits at 49.8 ft, so the channel is roughly 19.5 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.
