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 West Main (FM 518) reads around 4 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 17.0 ft.
The bottom of the channel here sits at 4.0 ft, so the channel is roughly 13.0 ft deep at this crossing. City of League City publishes the top-of-bank figure with each reading; it is their reference, not an estimate made here.
