Grass Lake Prairie

The project involves the design and installation of 3 low velocity fish barriers on Bone and Moody Lakes. This project will provide for the long term enhancement of native aquatic vegetation, a high quality fishery, and improved water quality by controlling rough fish populations. The barriers along with future harvesting will allow for the control of rough fish at populations that are conducive to achieving the management goals of the DNR & District for these lakes. This technique which is new to Minnesota will allow for the almost complete prevention of fish migration in an area where there is not enough slope for a standard velocity barrier and to avoid the high operating cost and uncertain control of electric barriers. This type of barrier would be valuable in numerous locations throughout the state with flat topography and future designs can further refined and guided by the experience in Bone and Moody Lakes.
