Introduction

A catchment-wide monitoring network is important in any catchment study. It is necessary to know the current status of water quality and river health and to use these results as baselines against which future interventions or changes can be measured.

One of the issues that is being addressed as part of the Motueka ICM project is how water quality varies across the catchment. The main questions involved with this work are:

Research Approach

Initially, routine monitoring was carried out monthly, but later, due to the cost, the frequency was extended out to 3-monthly and only at stable flows (not after any significant rain). In the field, a range of parameters are measured including: DO (mg/L), DO (% Saturation), Temp, Water Clarity, Conductivity, pH, flow at ungauged sites. Other parameters for which Samples collected for subsequent laboratory analysis include: E.coli, faecal coliforms, and nutrients (DRP, TP, NO3-N, TN; at a few sites only). In the past many samples were taken for Suspended Solids (Total, fixed and volatile) and Campylobacter.

There are 16 monitoring sites covering a range of stream sizes, geologies and vegetation covers.

Research Results

A technical report has also been prepared (Tasman District Council Ref: R05007 and Cawthron Report No. 933 , June 2005)(see Publications 2004-2005") by Roger Young (Cawthron Institute), Trevor James (TDC) and Joe Hay (Cawthron Institute) presenting results of the Tasman District Council’s “State of the Environment Surface Water Quality Monitoring Programme from 1999 to April 2004.

This report incorporates monitoring data collected by National Water Quality Network (NIWA) from 1989 to 2003 and other data including data collected as part of the ICM Motueka programme.
