30 The assessed reach of Mataura Stream (adjacent to the proposed works site) follows a natural flow-path at the base of a large gully system with gully sides that varied from steep to flat flood plains. The hard-bottom stream bed predominantly consists of gravels, cobbles and boulders with occasional areas of silt and sand in less exposed sites where flow velocities are reduced (i.e., stream edges). Fieldwork to assess the ecological values of the Mataura Stream was carried out in July 2020, and after further refinement of the project footprint, the unnamed tributary 2 was sampled in January 2021. A description of the habitat at the sampled sites is provided in Appendix 4.
