Flood stages are today's NWS stages; "highest in their record" counts gauges whose peak in that flood is the highest in their comparable USGS annual record. Allison and Katrina predate USGS's 15-minute archive here, so their pages use annual peaks. Floods since September 2026 are in the storm archive.
