the consents,
including upgrading the fish pass, undertaking monitoring of the erosion of the river bed and
banks around the scheme, and monitoring of the effects of the scheme on the residual flow
reach. This includes no or inadequate baseline information being collected on the trout
communities and recreational activities of the residual flow reach, despite the scheme now
being operated whenever flows allow. Of most concern, was the provision of false data. In this
case, the Company had

Proposed River Control
and Flood Protection Bylaw
for Taranaki
Pursuant to section 156 of the Local Government Act 2002, the Taranaki
Regional Council gives notice that it has prepared the Proposed River Control
and Flood Protection Bylaws for Taranaki.
The Proposed River Control and Flood Protection Bylaws for Taranaki, as well as
the Statement of Proposal and supporting documentation, is available:
• On the Taranaki Regional Council website at …
Manganui River, although due to
a mechanical failure, some flows were provided late. Monitoring shows that some improvement is necessary
in the control systems managing the provision of flushing flows to the Mangaotea Stream. This has been
formally communicated to Trustpower.
Following the establishment of the 400 L/s residual flow limit in 2002, the difference in water temperature
between natural flows in the Manganui River and those in the residual flow reach (downstream of the weir)
Culvert
A pipe, box structure or covered or arched channel
that has an inlet and outlet which is in, and connects
the water or bed of, the same river or connected area.
Weir
An open-topped structure across the full width of any
river or connected area that:
alters the water level and the flow characteristics
of the water; and
allows water to flow passively through or over the
top.
Dam
A structure whose purpose is to impound water
a severe weather event, while the
other two related to insufficient residual flow at a time when maintenance required the control gates to be
manually controlled. These incidents were all of short duration (no more than 4 hours).
Compliance with flushing flow requirements was good with regards to the Manganui River requirements,
but some improvement is necessary regarding the Mangaotea Stream requirements, where only one of the
four flushing flows was provided as required. This is an

Groundwater resource suggests that it is not likely to play a major role as an irrigation
supply option for the region.
Analysis of surface water availability and reliability was carried out on four rivers
(Waitotara and Whenuakura in the east Hawera area and Kapoaiaia and Punehu
streams in the Opunake area). These were chosen primarily because of the flow data
available and / or the relative catchment size.

Company demonstrated an overall good level of environmental
performance.
The Patea HEPS was visited two times during the monitoring period, being two site inspections. In addition,
analysis was conducted of generation data, lake level data, Patea River flow and groundwater abstraction
data provided by the Company. The Council also reviewed a number of reports submitted in accordance
with consent conditions. There were no hydrological inspections programmed for the 2018-2019 period, but
