# //RATING REMARKS="Rating for new gage location US of the gage house after gage was moved upstream with a documented +0.17 ft difference in elevation.  QMs used for rating development: 754, 799 and 886M - 889.  886M was created (not published) to assist with rating development.  Rating was originally drawn through QMS 754, and 799 to assist with slope (highest and most recent QMs made when gage was in its original location the inside well).  The rating was only extended to 5.87 ft /4395 cfs due to upper end uncertainty and is no more than twice the highest amount measured (QM 888).  Lower end taken to 0.65 ft, just below lowest stage of 0.73 ft from 2000-2018 (when gage was at its original location). Rating will need to be updated after higher and lower QMS are made. "
