# //RATING REMARKS="Office Note 7/16/26 EEE: Revised and reviewed Rating 22.0. There were no reversals found in the spreadsheet reversal tool. Started for the 2025 Spring season for lower end fill, and intermediate and upper end scour. The lower end is defined with an offset of 2.00 ft as determined from recent GZF measurements. The slope of 2.52 is indicative of section control and derived by recent measurements 735-737. A breakpoint at 3.10 ft, offset = 2.40 ft occurs where the riffle section control with split channels and gravel bar becomes submerged and transitions to channel control at a constriction downstream. The upper end is defined by recent Meas. 731 and historic Meas. 583 (indirect). It is extended to 8.54 ft and 1990 cfs. More definition needed throughout as scoured banks have caused instability in the control, more so in the intermediate and upper range.  Bypass flow likely occurs as the left bank becomes overtopped downstream near the fenceline at extreme high stages."
