MAKOTUKU RIVER AND WHANGANUI RIVER LEVELS SIT ABOVE MINIMUM FLOW

MAKOTUKU RIVER AND WHANGANUI RIVER LEVELS SIT WELL ABOVE MINIMUM FLOW

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

The graph for the Makotuku River over the last week shows a peak on 8 February following heavy rainfall and another peak when rain fell overnight on 13 February. The Makotuku River level currently  sits at 348 litres per second (l/s) well above the minimum flow level where restrictions are put in place of 115 l/s.

The graph for the Whanganui River shows similar peaks on 8 February and 13 February when rain fell. The Whanganui River level currently sits at 40 cubic metres per second (m3/sec), well above the minimum flow level of 29m3/sec.

 

Past trends show that river levels can drop quickly following drier weather, which we historically have experienced in February. The Ruapehu District is reminded to be water wise. Every drop counts!
