This alternative would consist of retaining Union Street Dam, along with the existing fish ladder and DNR weir operation. In addition, Brown Bridge Dam will be repaired and retained. The fish ladder at Union Street would be operated to allow native species of Great Lakes fish and salmon and trout to pass around the dam, but invasive aquatic species would be blocked at Union Street. Sabin Dam would be breached to allow a free flowing river to be restored from the upstream end of Boardman Pond to Boardman Lake. Boardman Dam would be breached and Boardman Pond would be replaced with a river. The Brown Bridge Dam would be repaired and retained without any action to mitigate the impact of warm water discharge on downstream coldwater habitat.
