The flood phase definitions relate to the Skykomish gage operated by Snohomish County since 1999. Water surface readings from the new gage (USGS 12131500 South Fork Skykomish River at Skykomish, WA) show different gage heights for the same river level. These 4 flood phase thresholds equate to gage heights of roughly 21.5, 23, 25, and 27 feet at the new USGS gage. The USGS will be adjusting their flow estimates from the new gage during the 2016-2017 flood season.
