NR 323.04(1)(c)11.h. h. Follow the most recent department approved disinfection protocols or department approved best management practices for infested waters. The department shall maintain on its website and make available at its offices a list of the most recent disinfection protocols or department approved best management practices for invasive species and viruses.
NR 323.04 Note Note: See the department's website at dnr.wi.gov under the topic “Waterway and Wetlands". Recommendations for additional disinfection or decontamination protocols or department approved best management practices may be submitted to the department for review and approval to be added to this list.
NR 323.04(1)(d) (d) Fish crib standards. In addition to the standards in par. (c), fish cribs shall meet the following requirements:
NR 323.04(1)(d)1. 1. Fish cribs shall have a minimum of 5 feet of water over the top of the structure. The depth and clearance of the fish cribs shall be based on the normal lowest water level condition during a calendar year.
NR 323.04(1)(d)2. 2. Fish cribs shall be constructed of biological materials, with the exception of fastening and anchoring devices.
NR 323.04(1)(d)3. 3. The dimensions of a fish crib shall be no larger than 8 feet tall by 8 feet long by 8 feet wide.
NR 323.04(1)(d)4. 4. Fish cribs may not be placed within 100 feet of swimming beaches or swim rafts.
NR 323.04(1)(d)5. 5. Fish cribs may not be located in soft sediment or muck that is greater than 12 inches in depth.
NR 323.04(1)(d)6. 6. Fish cribs may not be placed where the bottom contour of the waterway exceeds a slope of 4-foot horizontal to one-foot vertical.
NR 323.04(1)(d)7. 7. Fish cribs shall be adequately anchored to prevent movement.
NR 323.04(1)(e) (e) Spawning reef standards . In addition to the standards in par. (c), spawning reefs shall meet the following requirements:
NR 323.04(1)(e)1. 1. Spawning reefs shall be constructed of an aggregate of clean, uncrushed gravel and rock from 2 to 8 inches in diameter, in a ratio of approximately 30% ranging from 2 to 4 inches in diameter and approximately 70% ranging from 4.1 to 8 inches in diameter.
NR 323.04(1)(e)2. 2. Spawning reefs shall be placed in a linear form parallel to the shore.
NR 323.04(1)(e)3. 3. Spawning reefs shall be no longer than 100 feet along the shoreline and no wider than 30 feet perpendicular to shore and may not be placed more than 100 feet from shore.
NR 323.04(1)(e)4. 4. Spawning reefs shall be placed where water depths range from 0 to 5 feet.
NR 323.04(1)(e)5. 5. Spawning reefs may not be placed where the bottom contour of the waterway exceeds a slope of 4-foot horizontal to one-foot vertical.
NR 323.04(1)(e)6. 6. Spawning reefs may not be placed where the bottom substrate composition consists of less than 90% clean sand.
NR 323.04 Note Note: Natural walleye spawning reefs generally consist of substrates 2-8 inches in diameter with rounded edges. Natural walleye spawning reefs are located adjacent to gently sloping shorelines in shallow water. Walleye spawning reefs require a moderate amount of wave action to keep the substrate clean of algae and provide adequate water circulation for incubating eggs. The requirement of 90% clean sand indicates a lack of spawning habitat, the appropriate wave action, and substrate capable of supporting the reef. If the water depth remains less than 5 feet and the bottom contour remains less than 10:1, a maximum location of 100 feet from shore is required to reduce navigation concerns.
NR 323.04(1)(e)7. 7. Any person placing a spawning reef shall, within 30 days after placement, provide written notice to the president or chair of any lake association, property owners association or lake district. The notice shall include a description of the spawning reef and include a lake map identifying the exact location of the reef. The person is also responsible for posting a laminated copy of the same map, within 30 days after placement, at all public boat landings on the waterbody, where the reef is located, for a period of not less than one year.
NR 323.04(1)(f) (f) Wing deflector standards . In addition to the standards in par. (c), wing deflectors shall meet the following requirements:
NR 323.04(1)(f)1. 1. Design and placement of wing deflectors shall follow the recommendations in Guidelines for Management of Trout Stream Habitat in Wisconsin by Ray J. White and Oscar M. Brynildson, Wisconsin Department of Natural Resources.
NR 323.04 Note Note: Copies of these publications may be inspected by contacting the local department fisheries biologist or public library.
NR 323.04(1)(f)2. 2. Wing deflectors may only be placed in navigable streams which are less than 5 feet wide, measured from ordinary high water mark to ordinary high water mark.
NR 323.04(1)(f)3. 3. Wing deflectors may not extend more than 25% across the stream width.
NR 323.04(1)(g) (g) Tree drops. In addition to the standards in par. (c), tree drops shall meet the following requirements:

NR 323.04(1)(g)3. 3. Tree drops shall be securely anchored to the shore at intervals no less than 50 feet apart.
NR 323.04 Note Note: Local zoning ordinances may place restrictions on cutting trees in the shoreland zone. The riparian is responsible for ensuring that their tree drop project is in compliance with any local zoning requirements.
NR 323.04(1)(h) (h) Half-log structures. In addition to the standards in par. (c), half log structures shall meet the following requirements:

NR 323.04 Note Note: Eligibility for an exemption or general permit does not automatically result in a federal permit or state water quality certification for fill in wetlands. Some projects involving minimal wetland fill may be eligible for authorization under a U.S. Army Corps of Engineers general permit which has already been granted state water quality certification or a general permit under s. 281.36 (3g) (b), Stats. (under development) All other projects affecting wetlands will require individual water quality certification including public notice as required by s. 401, Federal Clean Water Act, and s. 281.36 (3b) (b), Stats., and carried out under chs.
