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 Max Road reads around 42 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 51.5 ft.

The bottom of the channel here sits at 41.0 ft, so the channel is roughly 10.5 ft deep at this crossing. Brazoria Drainage District 4 publishes the top-of-bank figure with each reading; it is their reference, not an estimate made here.
