Current Freshwater State
The MDC surface water quality monitoring network was updated in 2020 to better align with the requirements of the NPSFM. Two new surface water quality monitoring sites were introduced in 2023 for the State of the Environment in this FMU. These are anticipated to be measured monthly, although this will depend on resourcing as these are remote sites.
The Waiau-toa/Clarence River is currently monitored by Environment Canterbury (ECan) and the Marlborough District Council will be working with ECan in relation to this monitoring.
Water quantity and use
There is presently minimal demand for water abstractions within the Waiau-toa/Clarence FMU. Farming requires water for stock, which is provided for by the rivers. There are only two take consents for the FMU, which use water for wilding pine control. The numbers are correct as at October 2023.
