In relation to the operation of the NPWWTP, NPDC
and the effect of the road embankment cutting off the river berm flood overflows across
the Karaka flats, thereby concentrating all the flood flow through the SH3 bypass bridge, had
changed the flood flow characteristics of the river in this area. This resulted in extensive
modification being required to the original scheme works in the section of the scheme
between the Town Bridge and the new State Highway Bridge.
