B-6 – Area 6 – Assessment of Environmental Effects 23 2.15 AQUATIC ECOLOGY A description of the aquatic ecology values in proximity to Area 6 is provided in Boffa Miskell (2022a), a copy of which is provided in Part H of these application documents. Boffa Miskell (2022a) describe the streams within Area 6 as being of moderate ecological value, noting that: The streams are historically highly modified with streambeds smothered by fine sediment; partially a result of their predominantly pasture catchments; Macroinvertebrate communities are dominated by tolerant taxa, while the presence of EPT taxa was relatively low; and Fish fauna are sparse, with only shortfin eel species recorded during surveys. There are no fish barriers from the confluence of TB1 with the Ohinemuri River until a large natural waterfall is encountered in the upper reach of the tributary, outside the NRS footprint. There is a wetland area within the footprint of the proposed NRS (see Wetland TB1 – 1c in Figure 13 below). It was formed during and following the construction works for the Northern Stockpile and is a constructed wetland.
