In addition the section control appears to have filled. Rating No. 8.0 also adrresses changes to section. Assuming GZF is somewhere between 1.3 and 1.9 ft. no good current GZF (last noted 1.56 05/22). Reviewed by kalaughl, new rating looks reasonable, a few older measurements were discounted as control appears to be generally scourring over time. A few unnecessary rating points were removed, but the rating appears to be a general good representation of the channel in recent history." # //RATING EXPANSION="logarithmic" # //RATING OFFSET1=1.400000E+00 # //RATING_INDEP ROUNDING="????"
