A flood alert was issued in the Waikato yesterday because low-lying farmland and communities will be threatened by rising river levels over the next 48 hours.
State Highway 1 at Rangiriri may be closed by flooding today as the Waikato River crosses the spillway to Lake Waikare.
Environment Waikato says that whileflooding is easing at the southern end of the river at Lake Taupo, it takes several days for the floodwaters to move down the river to the sea, and peaks even higher than in the 1998 flood are expected through the lower Waikato.
The spillway at Rangiriri, used for the first time in 27 years in July 1998, is designed to take floodwaters to the lake when flows are at their peak.
Scott Fowlds, manager of Transit NZ's asset management group, said water was likely to begin flowing across the road from about midday today and the river was expected to peak at Rangiriri at 2am tomorrow.
A peak is expected around 5.30pm tomorrow at Ngaruawahia at 13.7m, at Huntly around 10pm tomorrow at 11m and at Mercer around 3.30pm on Wednesday at 5.46m.
Environment Waikato was yesterday contacting affected landowners and monitoring the situation.

* Eight people stranded in a Department of Conservation hut on an island in the Cavalli group near Matauri Bay in Northland have been rescued by the Coastguard.
