NR 820.29 Review periods. NR 820.30 High capacity wells in groundwater protection areas. NR 820.31 High capacity wells near springs. NR 820.32 Projects with high water loss. NR 820.33 Public utility wells. NR 820.10NR 820.10 Purpose. The purpose of this chapter is to designate areas of the state, consistent with s. 281.34 (9) (a), Stats., in which impacts from groundwater drawdown and pumpage are such that regional planning and management is necessary to avoid, minimize and manage future impacts. This chapter also establishes review criteria applicable to high capacity well applications involving wells situated near springs, trout streams, outstanding resource waters, and exceptional resources waters, and involving groundwater withdrawals with high water loss.

In this chapter: NR 820.12(2)(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. NR 820.12 NoteNote: Copies of this document may be obtained from the Department of Natural Resources, Bureau of Fisheries Management and Habitat Protection, 101 South Webster Street, Natural Resources Building, PO Box 7921, Madison, Wisconsin 53707-7921.
NR 820.12(3)(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. NR 820.12(4)(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. NR 820.12 NoteNote: s. NR 142.02 (4) defines “consumptive use coefficient” to mean “a constant numerical measure, as determined under s.

NR 820.12(7)(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. NR 820.12(8)(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. NR 820.12 NoteNote: s. 281.34 (1) (am), Stats., defines “groundwater protection area” to mean “an area within 1,200 feet of any of the following: NR 820.12 Note1. An outstanding resource water identified under s. 281.15 that is not a trout stream. NR 820.12 Note2. An exceptional resource water identified under s. 281.15 that is not a trout stream. NR 820.12 Note3. 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).

NR 812.07 (51) defines “high capacity property” to mean “one property on which a high capacity well system exists or is to be constructed.” NR 820.12 NoteNote: s. 281.34 (1) (b), Stats., defines “high capacity well” to mean “a well that, together with all other wells on the same property, has a capacity of more than 100,000 gallons per day.” NR 820.12 NoteNote: s. NR 812.07 (53) defines “high capacity well system” to mean “one or more wells, drillholes, or mine shafts used or to be used to withdraw water for any purpose on one property, if the total pumping or flowing capacity of all wells, drillholes or mine shafts on one property is 70 or more gallons per minute based on the pump curve at the lowest system pressure setting, or based on the highest flow rate from a flowing well or wells.” NR 820.12 NoteNote: s. 281.34 (1) (c), Stats., defines “local governmental unit” to mean a “city, village, town, county, town sanitary district, utility district under s. 66.0827 that provides water, public inland lake protection and rehabilitation district that has town sanitary district powers under s. 33.22 (3), joint local water authority created under s. 66.0823 or municipal water district under s. 198.22.
