The lowest point of the notch was surveyed at 0.940 m. In order to minimize shift application and shift crossing the rating, recent measurements and survey data were used to refine the previous rating. The lower end was drawn to the right as the v-notch appears to be moving down. The break point present in prior rating was removed from where flow breaks out from the v-notch and is as now smoothed with descriptor points. The intermediate portion of the rating given more weight for recent measurements and drawn more to left. The upper end is the same as the previous rating above 2.50 m and 28.8 m/sec. It is extended to 3.90 m and 81.0 m\\ufffd/sec." # //RATING EXPANSION="logarithmic" # //RATING OFFSET1=9.400000E-01 # //RATING_INDEP ROUNDING="????"
