Annual water quality reports

We’re responsible for managing Otago’s surface water resources and carrying out regular and extensive long-term water quality monitoring, as part of our State of Environment (SOE) programme.

These reports are a snapshot of sites in Otago that are monitored by us and NIWA.

They provide more detailed information about your local lake or river.
