(b) Data on existing and potential uses of the water body and any use impairments. (c) Alternatives and recommended actions to protect or restore water resources or allocate uses of the water body. (20) “Crossing” means a bridge, culvert, or ford used to traverse a stream. (21) “Dam” has the meaning given in s. NR 333.03 (3) . (22) “Department” means the department of natural resources. (23) “Dry fire hydrant” means a structure or device to which a fire hose can be connected that is constructed below the ordinary high water in a navigable waterway for the purpose of providing water for fighting fires. (24) (a) “Enclose” means a condition created when a structure or crossing is placed in or over a waterway in a manner that completely blocks or prevents typical public navigational or recreational access to a portion of the waterway, and for which there are no alternate public access opportunities. (b) “Enclose” does not include placement of a culvert or bridge that has been granted a waiver to navigational clearance requirements under s. NR 320.08 or authorizations to enclose a navigable waterway under s. 30.196 , Stats. (25) “Erosion intensity” or “EI” means the degree of erosion as estimated under s. NR 320.11 (2) . (26) “Fish crib” means a man-made 3-dimensional habitat structure composed of biological or inert materials designed specifically to attract and concentrate fish. (27) “Fish habitat structure” means a fish crib, spawning reef, wing deflector, boulder placement, weir, lunker, half-log, rock, brush bundle, cross-channel log, skyhook, rock deflector, coconut fiber roll, cross vane, root wad, fish stick, or similar device that is placed on the bed of a navigable water for the purpose of improving fish habitat. (28) “Fish stick” means a large woody habitat structure made of whole trees that may be grouped or attached together and is anchored to the shore, bed, or bank of a lake and may be partially or fully submerged near the shoreline. (29) “Ford” means a structure that consists of rock or gravel placed on the bed of a stream to facilitate crossing the stream and that is placed in a manner that mimics the natural bed elevation of the stream. (30) “Frozen conditions” means when a waterway is covered with ice thick enough to support vehicles. (31) “Grading” means the physical disturbance of the bank by the addition, removal, or redistribution of soil. (32) “Half-log” means a man-made structure composed of a log sawed lengthwise and anchored flat side down to the bottom of a lake or stream using steel rods for the purpose of providing habitat for fish. (33) “Hard armoring” means a shore erosion control structure that relies solely on inert materials and includes but is not limited to riprap and seawalls. (34) “High energy site” means a site where the storm-wave height calculated under s. NR 320.11 (1) is greater than or equal to 2.3 feet or where the erosion intensity score calculated under s. NR 320.11 (2) is greater than 67. (35) (a) “Impoundment” means the pool of water created by a dam. (b) “Impoundment” does not include any of the following: 1.
