Current through June 24, 2024
In this chapter:
(1) "Approval" means an approval issued by
				  the department under s.

				  2001 Stats., s.
				  281.34(2)
				  or
				  281.41, Stats.,
				  prior to construction of a high capacity well.
(2) "Class 1 trout stream" means a stream,
				  portion of a stream or a farm drainage ditch with a prior stream history that
				  contains a self-sustaining population of trout and is classified as such in
				  Wisconsin Department of Natural Resources publication PUB-FH-806 2002,
				  Wisconsin Trout Streams. Farm drainage ditches that support self-sustaining
				  populations of trout but do not have a prior stream history are not trout
				  streams for purposes of this chapter.

(3) "Class 2 trout stream" means a stream,
				  portion of a stream or a farm drainage ditch with a prior stream history that
				  contains a population of trout made up of one or more age groups, above the age
				  one year, in sufficient numbers to indicate substantial survival from one year
				  to the next, but in which stocking is necessary to fully utilize the available
				  trout habitat or to sustain the fishery and is classified as such in Wisconsin
				  Department of Natural Resources publication PUB-FH-806 2002, Wisconsin Trout
				  Streams. Farm drainage ditches that meet these criteria but do not have a prior
				  stream history are not trout streams for purposes of this chapter.
(4) "Class 3 trout stream" means a stream or
				  portion of a stream that has marginal trout habitat with no natural
				  reproduction of trout occurring, requiring annual stocking of trout to provide
				  trout fishing, and generally without carryover of trout from one year to the
				  next and is classified as such in Wisconsin Department of Natural Resources
				  publication PUB-FH-806 2002, Wisconsin Trout Streams. Farm drainage ditches
				  that meet these criteria but do not have a prior stream history are not trout
				  streams for the purpose of this chapter.
(5) "Consumptive use coefficient" has the
				  meaning specified in s.
				  NR
				  142.02(4).
Note:
s.
					 NR
					 142.02(4) defines "consumptive use
					 coefficient" to mean "a constant numerical measure, as determined under s.
					 NR 142.04(1) to
					 (4) which is used to determine the
					 consumptive use portion of a facility's withdrawal".
(6) "Department" means the department of
				  natural resources.
(7) "80%
				  exceedance flow" means the flow in a stream that, based on statistical
				  probability, will be exceeded 80% of the time on an annual basis.
(8) "Groundwater management area" means a
				  multi-jurisdictional area including towns, cities, villages and counties within
				  which the level of the groundwater potentiometric surface in any of its
				  underlying aquifers has been reduced by 150 feet or more from the level at
				  which the potentiometric surface would be if no groundwater withdrawals had
				  occurred.
(9) "Groundwater
				  protection area" has the meaning specified in s.
				  281.34(1)
				  (am), Stats.
Note:
s.
					 281.34(1)
					 (am), Stats., defines "groundwater protection
					 area" to mean "an area within 1,200 feet of any of the following:
1. An outstanding resource water identified
				  under s.
				  281.15
				  that is not a trout stream.
2. An
				  exceptional resource water identified under s.
				  281.15
				  that is not a trout stream.
3. A
				  class I, class II, or class III trout stream, other than a class I, class II,
				  or class III trout stream that is a farm drainage ditch with no prior stream
				  history, as identified under sub. (8) (a).
