How to read this gauge

The number above is an elevation, not a water depth. It is the height of the water surface above mean sea level, so Rankin Road reads around 53 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 66.9 ft.

The bottom of the channel here sits at 52.6 ft, so the channel is roughly 14.3 ft deep at this crossing. Harris County publishes the top-of-bank figure with each reading; it is their reference, not an estimate made here.
