Currentness
(a) Dams and structures that act as dams constructed in the channels of intermittent streams must meet the following criteria:
(1) A study shall be submitted to the board confirming that the installation of a dam will not increase flooding outside of the floodway or increase flood damages to third parties in the floodway.
(2) Erosion control may be required on the bank or levee slopes upstream and downstream of the proposed dam.
(3) Earthfill, including sand, and rockfill dams must be completely removed from the floodway prior to the beginning of flood season each year and may not be reinstalled prior to the end of flood season. (See Table 8.1.)
(4) All stanchions must be removed or lowered, and all flashboards and slide gates of a dam must be removed from the floodway prior to the beginning of flood season each year and may not be reinstalled prior to the end of flood season. (See Table 8.1.)
(5) The permittee must remove or lower all stanchions and must remove the flashboards and slide gates of a dam within twenty-four (24) hours after receiving written notification from the board.
(6) The permittee must remove an earthfill or rockfill dam within ninety-six (96) hours after receiving written notification from the board.
(7) Upon removal of an earthfill or rockfill dam, the material from the dam may not be stockpiled on the levee section or within the floodway.
(8) The permittee must provide warning signs upstream and downstream of a rockfill dam to protect boaters.
(b) Crop checks, ditch banks, ditch pads, road fills, and secondary levees installed within floodways and bypasses may not be reinforced or revetted and must be limited to a height that will not impair the floodway capacity. Crop checks, ditch banks and ditch pads are limited to a height of three (3) feet above the adjacent natural ground.
