How to read this gauge

Gage height is the height of the water surface above this gauge's own zero point, which sits at -1.05 ft NAVD88. It is not a water depth and not an elevation: add -1.05 ft to get the water surface elevation.

The flood stages are the National Weather Service's, on the same scale as the gage height; they are the NWS's references for this location, not estimates made here.
