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 (52 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.
