2694 Waipatiki Surface Water Investigation Bacteriological Water Quality Assessment

The monitoring programme undertaken by the Hawke's Bay Regional Council at Waipatiki during the 1997/1998 Christmas/New Year period aimed to look at the possibility of the septic tank infiltration in the surface water in the area during the period of peak usage.

Pakuratahi Land Use Project 1996-97 Annual Report

This annual report is produced as part of the ten year study of the Pakuratahi and
Tamingimingi catchments. The study monitors the changes associated with harvesting
of mature Radiata pine from the Pakuratahi catchment. This has been done by
assessing changes in sediment load with that of the typical east coast pastoral
catchment of the Tamingimingi.
This report provides a brief overview of rainfall and stream runoff during the period
July 1996 to June 1997. The past year has been the final year of calibration before the
first area of the Pakuratahi catclnnent is harvested, starting in October 1997.

SUSTAINABLE LOW FLOW PROJECT Ngaruroro River

The Ngaruroro is a strategically important water resource both for its ability to supply
water during frequent east coast droughts and as the major source of water for population
centres and agriculture on the Heretaunga plains.
Sustainable management requires the determination of a minimum flow and the allocable
volume of flow from the river. The minimum flow defines the environmental bottom line
and needs to address the flow requirements of the aquatic ecosystem and water quality and
cultural needs.
The minimum flow has been reviewed by the use of the Instream Flow Incremental Methodology
(IFIM) which assesses known habitat preferences of aquatic species against measured
variables of flow velocity, depth and bed material.

Assessment of the effects of artificial recharge on groundwater resources and river flows in the Heretaunga Plains

This report reviews existing groundwater, rainfall, river level, artificial recharge, and
groundwater usage data with the aim of assessing the effectiveness and efficiency of
artificial recharge in increasing groundwater levels in the 1-leretaunga Plains.

3521_AM97_13_Lake_Tutira_Eastern_side_Management_Plan_for_part_of_Tutira_Station_June_1997

The HBRC is examining the feasibility of purchasing approximately 463 ha on
the eastern side of Lake Tutira and developing it as a Conservation Reserve.
The land is presently owned by the Guthrie-Smith Trust and managed as part
of Tutira Station.
The project brief requires the consultants to identify the sustainable land uses
for each of the main components of the land, and to provide the management
criteria and the costs of establishing and managing these areas. There is to be a
balance between those uses, such as plantation forestry and pastoral grazing,
which may generate revenue and the planting or regeneration of land into
native species. The visual aspects of the completed project are considered to be
very important. The team is required to consult widely with tangata whenua,
conservation groups, user interest groups and other interested parties.
There has been widespread concern for many decades about the management
ofland in the catchment of Lake Tutira and the impact on the lake. Nutrientladen
runoff, soil erosion and access by animals to the streams and iak:e
margins has led to a marked decline in the quality of the water. Although
several actions have been taken to halt this decline, namely land retirement,
tree planting and the diversion of the main inlet stream, the impact of the
management of this large block ofland close to the lake edge has always been
of concern. After Cyclone Bola in 1988 there was a move by the Trust Board
to plant some of the. area in Pinus radiata, and smaller areas have been planted
in native species. A more recent proposal has also been put forward to plant
the balance in exotics and manage it as a commercial forest.
