More rain predicted for later this week is worrying Environment Waikato’s Flood Response Team as it makes the most of a lull between two troughs today.
Rain eased overnight, but heavy rain predicted on Thursday and Friday is likely to cause more problems as water is managed through the full Waikato River system.
Today, river levels on the Waipa are falling slowly and power company Mighty River Power held some water back in the hydro system at Karapiro to reduce flood levels downstream. However as the flood peaks from the past few days of heavy rain push through the system, flooding is expected at Mercer from tonight and over the next 48 hours.
The river is expected to come close to the top of stopbanks in places and localised ponding and flooding is expected as long flat peaks move slowly northwards. Farmers should move stock in low lying areas.
The MetService has predicted a new low on Thursday, bringing significant rain from Ruapehu north for the next few days. Unprotected areas are already flooding. Lake Taupo is also full and still rising.
