Data are presented as daily mean flow (l/s) and flow (m3/s). Three flow recorders are situated at the intake weir in the upper Deep Stream catchment(measuring Deep Stream flow above the weir (site 7444), inflow into the intake flume (site 7443) and flow returned to Deep Stream below the weir (site 7442). A further recorder (site 7445) measures the flow discharged into Lammerlaw Stream at the end of the diversion tunnel and pipeline. This Lammerlaw Stream water flows into Lake Mahinerangi providing additional water for the Waipori generation scheme. During 2008 the Deep Stream diversion was modified to allow water to be diverted to another storage reservoir via a gate structure in the pipeline 2 km before the Lammerlaw Stream Discharge flow recorder (site 7445). A new site (Deep Stream at Downstream Rollergate, site 7446) was installed in this new diversion in November 2008 to measure the flow to the new reservoir and 2 new hydro generation stations. Minimum flow requirements in the lower catchment are monitored at the site Deep Stream at 60 Foot Weir (site 74350). This site is 6 kilometres downstream of the Dunedin City Council Water Department intake on Deep Stream. To provide quarterly report to TrustPower Ltd on the catchment flow rates from river recorders for the period 1 October to 31 December 2014. These data are used to manage the Waipori Power Station.
