WATER SHARING PLAN FOR THE WYBONG CREEK WATER SOURCE 2003 - SCHEDULE 1
SCHEDULE 1 – Dictionary
The following definitions apply to this Plan
in addition to the definitions set out in the Act:
"account water" is the balance in a licence water allocation account at a
particular time.
Note: A licence water allocation account records water
allocations accrued under the licence as well as water allocations taken,
assigned or re-credited. The operation of the account is also governed by
rules for the carrying over of credits from one accounting period to the next
and rules for the maximum credit that may be allowed to accumulate in the
account as established in a water sharing plan. Water allocations are the
shares of available water accrued under an access licence from time to time as
a result of available water determinations.
"abandoned" refers to a water bore that is no longer being used.
"conversion factor" refers to the adjustment factor that is to be applied to
an access licence share component when it is cancelled in one water source,
and reissued in a different water source and visa versa, or when the access
licence is converted from one category to another. It is designed to provide
for the fact that the value of a unit of share component in terms of the
average water allocations that result from it may vary from one water source
to another, or from one category to another.
"endangered ecological communities" means ecological communities listed in
Schedule 1 of the Threatened Species Conservation Act 1995 or Schedule 4 of
the Fisheries Management Act 1994 .
"extraction limit" is a limit on the amount of water that may be extracted
from an extraction management unit.
"extraction management unit" is a group of water sources for the purpose of
managing long-term annual average extraction.
"farm dam" is a privately owned dam typically of earthen construction designed
to collect and/or store water for use on one or a few properties. It does not
include publicly owned dams or weirs. See also
"in-river dam" and
"runoff harvesting dam".
"flow classes" are categorised by the size and duration of flow levels in
unregulated rivers, for example: (a) very low flows may be a class on their
own,
(b) low flows may be categorised as ‘A’ class,
(c) moderate flows
may be categorised as ‘B’ class,
(d) high flows may be categorised as
‘C’ class,
(e) very high flows may be categorised as ‘D’ class, and
(f) extremely high flows may be categorised as ‘E’ class.
"flow gauging station" is a device that is used to measure the height of a
river, from which the flow in the river can be calculated.
"groundwater" is water that occurs beneath the ground surface in the saturated
zone.
"groundwater dependent ecosystems" are ecosystems which have their species
composition and natural ecological processes wholly or partially determined by
groundwater.
"individual daily extraction limit (IDEL)" is the volume of water that may be
extracted by an individual access licence on a daily basis from a particular
flow class.
"infrastructure" includes, but is not limited to, a: (a) flow gauging device
or any other appliance that is used to measure the height of a river relative
to a known datum point, from which the flow in the river can be calculated,
(b) flow announcement system which is the mechanism by which the Minister
communicates daily flow classes to the holders of an access licence within
this water source, or
(c) monitoring bore.
"in-river dam" is a dam on a 3rd, 4th or higher order river. 3rd, 4th or
higher order rivers are as defined in the order made under section 5 of the
Water Act 1912 in relation to the definition of a “river” gazetted 23
March 2001. See also
"farm dam" and
"runoff harvesting dam".
"management zone" is an area within the water source to which total daily
extraction limits are defined. Management zones are designated only where the
water source to which the plan applies is divided into areas and total daily
extraction limits are defined for each area.
"monitoring bore" refers to a bore constructed for the purpose of measuring
water levels and/or taking samples for water quality analysis.
"recharge" is the addition of water, usually by infiltration, to an aquifer.
"runoff harvesting dam" is a farm dam on a hillside or 1st or 2nd order stream
which collects and stores rainfall runoff. 1st and 2nd order streams are as
defined in the order made under section 5 of the Water Act 1912 in relation to
the definition of a river gazetted 23 March 2001. See also
"farm dam" and
"in-river dam". Note: This order refers to watercourses shown as blue lines on
topographic maps. The lines which are uppermost in a catchment are 1st order
streams, when two 1st order streams are joined they make a 2nd order stream,
etc. For more information see the Farm Dams Assessment Guide available from
the Department of Land and Water Conservation.
"total daily extraction limit (TDEL)" is the total volume of water that may be
extracted under access licences on a daily basis from a particular flow class.
