# //PARAMETER CODE="00060"
# //RATING ID="19.0" TYPE="STGQ" NAME="stage-discharge" AGING=Working
# //RATING REMARKS="The lower rating section is defined primarily by GZF 2.2 ft, which best matches the section control conditions, and by low flow measurements 1084, 1082, 1079, and 1075-1076. Meas. 1084 anchors low end due to its favorable conditions and agreement with 1085, while 1075-1076 and 1087 confirm behavior through roughly 3.3 ft. The middle section is guided by transitional flows approaching the breakpoint. Measurements show slight scour between March and May 2024, but still plot consistently toward the established curve, maintaining continuity toward channel control. The upper section is defined by channel\\u2011control measurements 1037 and 1069-1070, with 1069 representing the best midpoint. High\\u2011flow measurements 956 (4260 cfs) and 1037 anchor the upper extension and supports the 4.6\\u2011ft breakpoint. \\nReviewed EEE 5/21/26. Revised rating comments. Passed reversal spreadsheet. Drawn to slightly scoured side on lower end. Rating slope indicative of section control. Lowest output set at 15.9 cfs."
