# //RATING REMARKS="Rating 16.0 was developed due to an apparent fill change to the bottom end of R15.0. R16.0 was based on QMs under 8.00 ft made since resecion of WY21 HW and QMs above 8.0 ft since WY18 and historic HW QMs. QMs over 8.00 ft favor the left of R16.0 (as in previous Ratings as well) based on ADD3 Hydrographic comparison. Recent QMs above 8.00 ft typically plot within margin of upper portion of R16.0. "

# //RATING_DATETIME COMMENT="transition between R15.0 and R16.0 occurred at a GH of 6.08 ft. when the shifted R15.0 is equivalent to R16.0. Rating 16.0 was developed as QMs made following WY 2021 HW revealed significant fill had occurred at the site below the BP of R15.0. R16.0 was based on QMs under 8.00 ft made since regression of WY21 HW and QMs above 8.0 ft since WY18 and historic HW QMs. QMs over 8.00 ft favor the left of R16.0 (as in previous Ratings 14.0 and 15.0) based on ADD3 Hydrographic comparison. Recent QMs above 8.00 ft typically plot within margin of upper portion of R16.0. QMs below R16.0 BP also plot to the left but is believed to be a result of algae growth per control inspection notes.
