How to read this gauge
Gage height is the height of the water surface above this gauge's own zero point, which sits at 3.42 ft NAVD88. It is not a water depth and not an elevation: add 3.42 ft to get the water surface elevation.

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 (17 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.
