Water monitoring data

The Whangawehi Catchment Management Group has been monitoring water quality in the catchment for the last 5 years. 7 sites are monitored every second months including a site at the lower end (Mamangu) which monitored every month. This site is used as our indicator of what’s happening in the entire catchment. What we have observed is a significant improvement of faecal contamination since the restoration project started. This site has been below recreational guidelines for many years. However faecal contamination is still occurring in some tributaries mainly due to a high number of geese.
