126 Table 37: Five-yearly median and 5-yearly 95th percentile data for dissolved reactive phosphorous DRP (g/m3) across four sites sampled in the Ohinemuri River at Waihi from 2003-2021. Measures are colour coded according to the NOF Attribute parameters that they fall within (NPS-FM 2020): green = Attribute A; yellow = Attribute B; red = Attribute C or Attribute D (both of which fall below the National Bottom Line for NH4-N). Site locations are shown in Figure 14.
