Bone Lake Fish Barrier:
preventing the downstream migration of carp

EOR’s innovative rough fish barrier materializes interest of MN/DNR staff in a subsurface filtration lake inlet/ outlet that eliminates the passage of Aquatic Invasive Species (AIS). This low velocity fish barrier maintains water flow and lake levels while limiting upstream and downstream carp movement. One barrier was installed at the Lake’s inlet and the other located at the Lake’s outlet.

These subsurface inlet/ outlets will prevent the upstream migration of carp into Bone Lake, as well as out of Bone Lake – preventing the carp’s downstream migration after spawning. This approach will limit lake and wetland disturbance by rough fish, resulting in both water quality and habitat improvements. This installation represents the first implementation of this design approach at this scale.
