Nebraska Statutes 46-1611. Dam, defined
(1) Dam means any artificial barrier, including appurtenant works, with the ability to impound water, wastewater, or liquid-borne materials and which (a) is twenty-five feet or more in height from the natural bed of the stream or watercourse measured at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier if it is not across a stream channel or watercourse, to the maximum storage elevation or (b) has an impounding capacity at maximum storage elevation of fifty acre-feet or more, except that any barrier described in this subsection which is not in excess of six feet in height or which has an impounding capacity at maximum storage elevation of not greater than fifteen acre-feet shall be exempt, unless such barrier, due to its location or other physical characteristics, is classified as a high hazard potential dam.
Terms Used In Nebraska Statutes 46-1611
- Dam: means any artificial barrier, including appurtenant works, with the ability to impound water, wastewater, or liquid-borne materials and which (a) is twenty-five feet or more in height from the natural bed of the stream or watercourse measured at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier if it is not across a stream channel or watercourse, to the maximum storage elevation or (b) has an impounding capacity at maximum storage elevation of fifty acre-feet or more, except that any barrier described in this subsection which is not in excess of six feet in height or which has an impounding capacity at maximum storage elevation of not greater than fifteen acre-feet shall be exempt, unless such barrier, due to its location or other physical characteristics, is classified as a high hazard potential dam. See Nebraska Statutes 46-1611
- Department: means the Department of Natural Resources. See Nebraska Statutes 46-1613
- High hazard potential: means a hazard potential classification such that failure or misoperation of the dam resulting in loss of human life is probable. See Nebraska Statutes 46-1619
- Maximum storage: means the reservoir storage capacity between the top of dam elevation, or the maximum routed elevation of the probable maximum flood if lower than the top of dam elevation, and the lowest downstream toe or outside limit elevation of the dam. See Nebraska Statutes 46-1622
- Storage elevation: means the elevation of the reservoir surface associated with a level of impoundment, such as maximum storage or normal storage. See Nebraska Statutes 46-1633
- United States: shall include territories, outlying possessions, and the District of Columbia. See Nebraska Statutes 49-801
(2) Dam does not include:
(a) An obstruction in a canal used to raise or lower water;
(b) A fill or structure for highway or railroad use, but if such structure serves, either primarily or secondarily, additional purposes commonly associated with dams it shall be subject to review by the department;
(c) Canals, including the diversion structure, and levees; or
(d) Water storage or evaporation ponds regulated by the United States Nuclear Regulatory Commission.
