The Okeover stream was originally spring-fed but now primarily receives aquifer water used to cool buildings at the University of Canterbury. The lowered water table and displaced stream source results from nearby urbanisation. While its perennial reach was the focus of restoration efforts since 1998, it is classified as a highly disturbed ecosystem. The upper ephemeral section located offcampus relies on >60 variable stormwater discharge conduits for flow. Water quality and in-stream fine sediments are believed to inhibit biota recovery in this ecosystem. We quantified key metal contributions to the Okeover and its current chemical signature to prioritise recovery options.
