Lesser floods between them may be missing, so counts by decade are a floor. Categories use today's flood stages. Levees, dams and channel changes since a crest can make old and new stages not directly comparable. 05 Other gauges in Chelan County Chelan County: every hazard · River floods across the country · Washington
