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 East 8th Street reads around 12 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 21.8 ft.
The bottom of the channel here sits at 11.8 ft, so the channel is roughly 10.0 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.
