area under par. (b) the department determines that special measures relating to existing and potential groundwater withdrawal
are necessary in all or part of that area to prevent or remedy a significant reduction of a navigable stream’s or navigable lake’s rate
of flow or water level below its average seasonal levels, the department shall issue a decision on whether it recommends that
the legislature adopt, by statute, special measures relating to
groundwater withdrawal in all or part of that area. If the department issues a decision recommending that the legislature adopt,
by statute, special measures relating to groundwater withdrawal
in all or part of that area, the decision shall contain all of the following information:
1. A description of the extent to which the department has
determined that cumulative groundwater withdrawals in all or
part of the area cause, or are expected to cause, a significant reduction of a navigable stream’s or navigable lake’s rate of flow or
water level below its average seasonal levels.
2. A description of the concrete scientific information that
the department used to establish that there is a hydrologic connection between the groundwater in all or part of the area and the
navigable waters in all or part of the area and a causal relationship
between groundwater withdrawal in all or part of the area and an
existing or potential significant reduction of a navigable stream’s
or navigable lake’s rate of flow or water level below its average
seasonal levels, and the degree to which the department verified
the connection and causal relationship by the use of field work or
field study.

area studied under par. (b) after June 3, 2017, or who takes any of
the actions described in sub. (2g) (a) 2. to 4. in the area studied
under par. (b) after June 3, 2017, shall provide to the department,
with the owner’s annual pumping report under sub. (5) (e) 2. ,
readings of a water meter showing the volume of water usage of
that high capacity well in gallons.
(j) 1. The department may issue an approval under this section to a qualified lake association or lake district to construct and
operate a new high capacity well, or to operate an existing approved high capacity well, for the sole purpose of providing water
to a lake that is located wholly or partially in the area studied under par. (b) to assist the department in evaluating and modeling
the hydrology of that area under par. (b), if the department determines that the lake’s water level has been significantly reduced
below its average seasonal levels. For any approval application
submitted by a qualified lake association or lake district under
this paragraph, the department shall waive the application fee under sub. (2), expedite the review and approval process to the
greatest extent possible, and include, as a condition of the approval, a limit on the water level of the lake that may be reached
as a result of the water provided by the proposed well. The department may not issue an approval to a qualified lake association
or lake district under this paragraph if it determines that providing water from the proposed high capacity well to a lake is likely
to result in a violation of a water quality standard under s. 281.15
for that lake.

shall promulgate rules identifying class I, class II, and class III
trout streams for the purposes of this section. The department
shall identify as a class I trout stream a stream or portion of a
stream with a self-sustaining population of trout. The department
shall identify as a class II trout stream a stream or portion of a
stream 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. The department shall identify as a class III
trout stream 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. In the
rules under this paragraph, the department shall identify any
class I, class II, or class III trout stream that is a farm drainage
ditch with no prior stream history.

effects of wells constructed before May 7, 2004, that are located
in groundwater protection areas. Mitigation may include abandonment of wells and replacement of wells, if necessary, and
management strategies. Under the mitigation program, the department may order the owner of a well constructed before May
7, 2004, that is located in a groundwater protection area to undertake mitigation but only if the department provides funding for
the full cost of the mitigation, except that full funding is not required if the department is authorized under ch. 280 to require the
well to be abandoned because of issues regarding public health.
(9) GROUNDWATER MANAGEMENT AREAS. (a) The department shall, by rule, designate 2 groundwater management areas
including and surrounding Brown County and Waukesha County
consisting of the entire area of each city, village, and town at least
a portion of which is within the area in which, on May 7, 2004,
the groundwater potentiometric surface has been reduced 150
feet or more from the level at which the potentiometric surface
would be if no groundwater had been pumped.
(b) The department shall assist local governmental units and
regional planning commissions in groundwater management areas designated under par. (a) by providing advice, incentives, and

funding for research and planning related to groundwater
management.
(c) If the groundwater advisory committee created under
2003 Wisconsin Act 310, section 15 (2) (b) does not issue the report under 2003 Wisconsin Act 310, section 15 (2) (e) by January
1, 2007, the department shall promulgate rules using its authority
under ss. 281.12 (1) and 281.35 to address the management of
groundwater in groundwater management areas.
(d) If the department promulgates rules under par. (c) and the
rules require mitigation in the same or a similar manner as under
sub. (8) (d), the department may not require mitigation for a well
under the rules unless the department provides funding for the
full cost of the mitigation, except that full funding is not required
if the department is authorized under ch. 280 to require the well
to be abandoned because of issues regarding public health.
(10) RESEARCH AND MONITORING. To aid in the administration of this section the department shall, with the advice of the
groundwater coordinating council, conduct monitoring and research related to all of the following:
