NR 343.03(2)(2) “Artificial water body” means a proposed or existing body of water that does not have a history of being a lake or stream or of being part of a lake or stream. NR 343.03(3)(3) “Connects with a navigable waterway” means any artificial waterbody that is attached by means of enlargement or by a natural or artificial channel or drainage course, or an open or closed conduit, any of which tend to confine and direct flow into the existing navigable waterway.

NR 343.03(6)(6) “Land disturbing construction activity” means any man-made alteration of the land surface resulting in a disturbance to soil or existing vegetative or non-vegetative soil cover that may result in stormwater runoff and lead to increased soil erosion and movement of sediment into waters of the state. Land disturbing construction activity includes clearing and grubbing, demolition, excavating, pit trench dewatering, filling and grading activities. NR 343.03(7)(7) “Navigable waterway” means any body of water with a defined bed and bank, which is navigable under the laws of the state.

NR 343.03 NoteNote: This incorporates the definition at s. 30.01(4m), Stats., and current case law, which requires a watercourse to have a bed and banks, Hoyt v. City of Hudson, 27 Wis. 656 (1871), and requires a navigable waterway to float on a regularly recurring basis the lightest boat or skiff, DeGayner & Co., Inc. v. DNR, 70 Wis. 2d 936 (1975); Village of Menomonee Falls v. DNR, 140 Wis. 2d 579 (Ct. App. 1987). NR 343.03(8)(8) “Ordinary high water mark” means the point on the bank or shore up to which the presence and action of water is so continuous as to leave a distinct mark either by erosion, destruction of terrestrial vegetation or other easily recognizable characteristic. NR 343.03(9)(9) “Storm event” means any amount of precipitation equal to or greater than 0.01 inches with a minimum time between storms of 6 hours. NR 343.03(10)(10) “Stormwater” means runoff from precipitation including rain, snow, ice melt or similar water that moves on the land surface via sheet or channelized flow. NR 343.03(11)(11) “Stormwater management pond” means any temporary or permanent artificial water body designed to specifications generally accepted to reduce the water quantity or water quality impacts of stormwater and to hold water for any period of time.

NR 216.46 will need to add the information requested in pars. (b) to (e), (i) and (j). NR 343.05(3)(3) Erosion and sediment control best management practices. The erosion control plan shall include a description of appropriate erosion and sediment control best management practices that will be installed and maintained at the pond or artificial water body site to prevent pollutants from reaching waters of the state. The erosion control plan shall clearly describe the appropriate erosion and sediment control best management practices for each major land disturbing construction activity and the timing during the period of land disturbing construction activity that the erosion and sediment control best management practices will be implemented. The erosion and sediment control best management practices shall be designed in accordance with s. NR 216.46 (6). NR 343.05(4)(4) Erosion and sediment control technical standards.
