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 329.04 NoteNote: See the department’s website at http://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 329.04(2)(d)1.1. A ford may not be located in an area of special natural resource interest except for fords constructed for an agricultural use as defined in s. 30.40 (1), Stats. However, no ford may be placed within a public rights feature as described in s. NR 1.06. NR 329.04(2)(d)3.3. A ford shall be placed entirely within the riparian’s zone of interest, as determined by one of the methods outlined in ch. NR 326. NR 329.04(2)(d)4.4. A ford shall be designed and constructed to prevent structural failure and shall be maintained in good condition at all times. NR 329.04(2)(d)6.6. A ford shall only be constructed where the stream width is less than 100 feet, the normal stream depth is less than 2 feet, and where the streambed does not contain more than 6 inches of soft sediment. NR 329.04(2)(d)7.7. A ford shall consist of a 6- to 24-inch thick layer of 2- to 4-inch diameter rock or pre-cast reinforced concrete planks over a base of crushed rock with a total thickness not exceeding 24 inches. NR 329.04(2)(d)8.8. A ford shall be no more than 16 feet wide in a direction parallel to the flow of the stream. NR 329.04(2)(d)9.9. A ford shall have its top surface at the same level as the natural streambed immediately upstream and downstream from the ford. The placement of the ford may not result in the creation of an impoundment or dam upstream or a waterfall or riffle area downstream. NR 329.04(2)(d)10.10. The approach road to the ford may not have bank slopes steeper than 5-foot horizontal to one-foot vertical (5H:1V) toward the stream, or side slopes exceeding 2-foot horizontal to one-foot vertical (2H:1V). NR 329.04(2)(d)11.11. The approach road to the ford may not be constructed in or across a wetland. NR 329.04(2)(d)12.12. The approach road to the ford may not be raised above the elevation of the surrounding natural ground elevation. NR 329.04(2)(d)13.13. Any grading, excavation and land disturbance shall be confined to the minimum area necessary for the construction and may not exceed 10,000 square feet. NR 329.04(2)(d)14.14. All equipment used for the project shall be designed and properly sized to minimize the amount of sediment that can escape into the water. NR 329.04(2)(d)15.15. Material excavated from the streambed or banks may not be placed in any surface water body or wetland and may not be placed in a floodway. NR 329.04(2)(d)16.16. Construction of the ford may not occur during periods of high stream flow or high water conditions where the flow is not confined to the immediate stream channel. NR 329.04(2)(e)2.2. A boat landing may not be located in an area of special natural resource interest, except for boat landings constructed and maintained by a local, state or federal agency. However, no boat landing may be placed within a public rights feature as described in s. NR 1.06. NR 329.04(2)(e)4.4. A boat landing shall be placed entirely within the riparian’s zone of interest, as determined by one of the methods outlined in ch. NR 326. NR 329.04(2)(e)5.5. A boat landing shall be designed and constructed to prevent structural failure caused by wave, wind or ice action and shall be maintained in good condition at all times. NR 329.04(2)(e)6.6. Material removed or excavated to construct the boat landing may not be placed in a wetland, floodway or below the ordinary high water mark of any navigable waterway. NR 329.04(2)(e)7.7. A boat landing shall consist of a 6- to 24-inch layer of crushed rock, a 6- to 18-inch layer of crushed rock capped with a 4-inch minimum thickness pre-cast reinforced concrete planks or a cast-in-place reinforced concrete slab, each with a 6- to 18-inch crushed rock base. Pre-cast planks shall be connected to prevent displacement. NR 329.04(2)(e)8.8. A boat landing shall have a slope no steeper than 7 foot horizontal to one foot vertical (7H:1V) and may not exceed 50 feet in length or beyond the line of navigation, whichever is less.
