Water Restrictions and Whanganui River and Makotuku River Flow Graphs


Friday 1 May 2020

The Whanganui River continues to flow below minimum flow levels.  The Makotuku River is flowing above the minimum flow level.

Please actively participate and do your part to reduce household water consumption. 

Do not use water sprinklers.  Instead, use hand-held hoses to water your vegetable garden either first thing in the morning and in the evenings when the temperatures are cooler.

Avoid unnecessary water usage such as washing pathways or vehicles. 

Take short showers instead of running a bath.  Remember - Every drip counts.
