This helped with concavity of previous rating on lower end. Channel control for most stages until near 20.0 ft for overbank conditions as rating slope goes above 2.00. More weight given to recent measurements although historic ones were used to shape upper end. Generally, the overall rating was drawn slight to the right of most historical measurements due to recent scour. Some lower measurements in 2023 WY were not as weighted as much as scour condition was not evident in 2024 WY. Some minor reversals present but did not require smoothing." # //RATING EXPANSION="logarithmic" # //RATING OFFSET1=2.800000E+00 # //RATING_INDEP ROUNDING="????"
