The development for rating 12.0 utilized the most recent measurements 540 through 551 and the most recent GZF of -2.50 ft. Rating began with a 2-point straight line intersecting the bottom end of the spread, as long term scour is expected to continue. There are no supporting measurements for the top end, so the rating was extended to rating 11.0 top end but maintaining a straight line. The rating was then extended to zero flow with a point added to create a smooth transition to zero flow.\\n\\nReviewed and Approved by RKK 08/04/2026" # //RATING EXPANSION="logarithmic" # //RATING OFFSET1=-2.500000E+00 # //RATING_INDEP ROUNDING="????"
