The extension is a straight line extension to -1.80 ft. \\n\\nRating 24.1 is approved by KBW. Rating 24.1 is a straight-line extension on the lower end of rating 24.0 to account for channel scour. The straight-line extension is reasonable considering there are no discharge measurement data below -0.84 ft gage height, observed 01/14/2025, discharge measurement 923. It was noted by the reviewer that discharge measurement 923 was considered good, with a clear control, yet the measurement plotted -13% from rated. However, discharge measurements 920-922 verified the slope of the lower end that was extended plotting 2.0, -1.6 and 5.9%, respectively. The lower end of the rating that was extended is suitable for discharge computations and shifts can be easily applied as required to account for changes to the rated conditions.
