Poerua River is a river in
Mount Adams blocked the Poerua River, creating a landslide dam about 11 km upstream from the State Highway 6 bridge over the river. Despite fears of flooding and other damage, there were relatively minimal impacts when the dam was breached six days later, though significant quantities of coarse gravel
were deposited downstream and the river's course was changed in places.
