How to read this gauge

Gage height is the height of the water surface above the gauge's zero point. This gauge's zero is set at 0 ft NAVD88, so its gage height is the water surface elevation above that datum. It is not a water depth.

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.

Each dot is the highest gage height of a water year (October to September), from the USGS annual peak record, with recent years USGS has not published yet taken from its 15-minute readings and this site's own; hover a dot for its date. Dashed lines are NWS flood stages. Grey hollow dots (74 years) were measured on a different datum or at a different site, or before the gauge's datum last changed, so they are shown but not compared.
