B-2 – Area 4 - Assessment of Environmental Effects 11 For the most part the services cross streams and rivers at existing bridges, including the Ohinemuri River at two locations. A description of the aquatic ecology values of the Ohinemuri River is provided in the Area 5 sub-AEE. The exception are two unnamed tributary streams which are crossed by the Services Trench as it approaches the Waihi operations. These are outlined in Boffa Miskell (2022a) who make the following key observations in respect of those streams: One is a shallow stream feature approximately 5 m wide, which was completely covered in grasses and thick floating grass mats when visited; and The other is an entrenched watercourse running alongside a barberry hedge with a bank height of some 0.5 m.
