This flow is controlled by gates at the lake outlet, and travels several kilometres down the Monowai River before being diverted by a weir into a canal leading to the Power Station and released into the Waiau River. At the diversion weir, a flow is released through the fish-pass and down the Monowai River to maintain a minimum flow. The lake outflow is monitored at site no. 79712 (Monowai at Below Gates). Lake level is recorded at site no. 79713 (Lake Monowai at Hinchey’s Outlet). Flow down the lower Monowai River below the diversion weir is monitored at site no. 79715 (Lower Monowai at Below Weir); this station was installed on 10 April 2003 for resource consent monitoring. The report summarises the data from these sites for the quarterly period – 1 October to 31 December 2014, and in the context of the full record since 1977. Data and outputs cover: Daily Mean levels at Site 79713 Lake Monowai at Hinchey’s Outlet from 1 January to 31 December 2014. Daily mean outflows (m3/s) at Site 79712 Monowai River at Below Gates from 1 January to 31 December 2014. Daily mean inflows (m3/s) at Site 9540, Lake Monowai at Inflow from 1 January to 31 December 2014. Daily mean flows (l/s) at Site 79715, Lower Monowai River at Below Weir, from 1 January to 31 December 2014. Monthly mean levels (lake level in metres, in terms of Monowai datum) at Site 79713 Lake Monowai at Hinchey's Outlet from June 1977 to 31 December 2014. Monthly mean outflows (m3/s) at Site 79712 Monowai River at Below Gates from 1 October 1976 to 31 December 2014.
