Meeting 22 Ngaruroro and Tutaekuri catchments Water Quality 9

Meeting 22 Ngaruroro and Tutaekuri catchments Water Quality  General considerations and recap from last meeting Tutaekuri catchment:  NOF attributes for toxicity (ecosystem health) and E.coli (contact recreation) Ngaruroro and Tutaekuri catchments:  Algae and nutrients  Macroinvertebrates  Water clarity, sediment 10

Take home points from last meeting • Progress too slow • ‘Happy/ unhappy’ rating for current state not suitable • Unknown uncertainty behind data • Sometimes confusing Changes to this presentation :  Discussing attributes for Tutaekuri and Ngaruroro together  Replacement of rating happy/ unhappy with current state by prioritising responses instead  Tables now sorted separately for main stem and tributaries (management zones?)  Background information on the data  Ngaruroro macrophyte dominated lowland sites taken out of algae section 11

RESPONSE RATING NARRATIVE (PRIORITY) Water quality and/or quantity needs of the values are not being met or High There is a high risk that values will be significantly adversely affected without management intervention Water quality and quantity needs of the values are not being fully met or Medium There is a risk that values will be adversely affected without management intervention Water quality and quantity needs of the values are being mostly met or There is a low risk that values will be adversely affected Low or Management response required for other priority areas may manage this aspect at higher level of protection Water quality and quantity needs of the values are being fully met No and There is a very low risk that values will be adversely affected 12
