The applicant proposes to stabilize existing site conditions and restore recreational opportunities in the Little Sioux River at the Linn Grove Dam after a 2019 flood event breached the earthen south extension of the dam. The newly eroded channel south of the dam and former river channel will be stabilized and partially filled to restore the former dam crest elevation, however the new channel will be maintained as an additional conveyance channel to expand the unit width of the overall structure. A total of 3,980 linear feet of rock bank stabilization (mostly Iowa DOT Class D and some Class B quarry rock revetment) are proposed. Rootwads will be installed at the left descending bank of the new channel for a distance of 203 linear feet at the upstream end, and 100 linear feet at the downstream end where a floodplain channel will be reconnected to the new channel. The rootwads will be collected from the project site where tree removal is unavoidable due to site restoration earthwork.
