Tukituki River Catchment Water and Soil Management Plan
This Water & Soil Resource Management Plan (W.S.R.M.P.) is
designed to ensure the long term wise management of the water
and soil resources of the Tukituki River Catchment. There is
no statutory responsibility to prepare this plan. However, it
fills an important educational role for land and water users
and planning authorities. The plan also sets out methods by
which the Board can implement its statutory responsibilities
under the Soil Conservation and Rivers Control Act 1941 and the
Water and Soil Conservation Act 1967. These two Acts require
the Board to make provision for the following:-
a. conservation of soil resources and prevention of damage
to property by erosion;
b. increased protection of property from flooding;
c. promotion and control of land drainage;
d. promotion of conservation and beneficial uses of water;
e. allocation of natural water;
f. maintenance of water quality standards;
g. promotion and control of the multiple use of water;
h. preservation and protection of the wild, scenic and
other natural characteristics of rivers, streams and
This report covers the investigations and design work carried out by the Boards Chief Design Engineer Mr G. Williams, who assisted by other Board staff, re-assessed the physical characteristics of the river, considered the methods of design and construction of the current scheme works and identified the most effective and cost efficient means to provide a high standard of flood protection to approximately 22,500 ha of developed land on the Heretaunga Plains.
4740 RM 15-03 Heretanga Plains Irrigation Study 1985optimized
This survey was carried out to determine a basis from
which the quantity of water taken by rural users from
the Heretaunga Plains Groundwater System could be
Eight representative areas on the Heretaunga Plains
were selected (Figure 1). The 110 water right holders
(operating 163 water rights) within these areas were
required to complete daily Log sheets detaiLing the rate
and duration of taking between 14 January and 17 February
Data obtained in this matter was analysed and abstraction
rates were compared to those authorised by water rights
and to potential evapotranspiration (PET).
During the study period there was 40.4 mm of rain. This
occurred over 6 rain days although there were only two
rain days when rainfall was significant, 27 January (14 mm)
and 17 February (16.7 mm) (See Table 1).
Under Section 20 (5) of the Water and Soil Conservation Act
1967, the Hawke's Bay Catchment Board and Regional Water
Board is responsible for a number of functions and duties:
(a) .... the Board shall promote the protection of water
supplies of local authorities and the conservation
and most beneficial uses of natural water within the
region including the planning for and promotion of
works and projects for the conservation of natural
water, and projects for the multiple use of natural
(b) .... the Board shall have the function of recommending
maximum and minimum levels, and minimum standards of
quality to be sought or permitted for the natural
water in lakes, both natural and artificial, and the
minimum acceptable flow and minimum standard of
quality of the natural water of any river or stream
within the region.
(c) .... the Board shall investigate and record all
significant resources of natural water within the
region, and its quality and availability, and shall
check so far as possible upon the effects of damming,
abstractions, diversions, pollution and other factors
affecting the volume, quality and availability of
natural water above and below ground within the
(d) .... the Board shall collect, sort and record data on
resources and availability of natural water, and shall
supply to public authorities and the public information
so collected. "
As a r esult of the deteriorating water qu a lity of Lake Tutira,
Hawke's Bay , a n Investigative Committee was set up in 1974 . This
Committee brought down a Report entitled
"Lake Tutira and its Catchment
Current Condition and Future Hanagement"
in which not only were the causes of lake deterioration examin ed, but
also r ecommendations made as to the measures t ha t would be r equir ed to
r estor e the l ake. Based on these recommendations the Lake Tutira
Catchment Contro l Scheme was prepar ed by t he Hawke ' s Bay Catchment
Board in February 1980 and the Scheme approved for Government funding
in December 1980.
An essential element of the Catchment Control Scheme, based on the
Technical Committee Report, was that a Lake Shore Reserve area should
be established .
