Note: 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);
