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 (39 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.

The highest crests the National Weather Service lists for this gauge, as published. They can differ from the USGS annual peaks above: USGS records the year's highest gage height, which is not always the crest the NWS lists for the same flood.
