MAKOTUKU RIVER AND WHANGANUI RIVER LEVELS REMAIN ABOVE MINIMUM FLOW

The latest river flow data from the Whanganui River and the Makotuku River show that average levels for both rivers are above minimum flow levels when water restrictions are put in place.

The graph for the Makotuku River over the last week shows that river levels have steadily dropped over the week with drier weather to where they currently sit at 149 litres per second (l/s), above the minimum flow level where restrictions are put in place of 115 l/s.  

The graph for the Whanganui River shows a similar curve, with river levels dropping over the week to where they currently sit at 35 cubic metres per second (m3/sec), well above the minimum flow level of 29m3/sec.

River levels are expected to remain above minimum flow levels over the coming week with rain forecast for both Raetihi and Taumarunui.


 

Past trends show that river levels can drop quickly following drier weather. The Ruapehu District is reminded to be water wise. Every drop counts!
