UNDATED (KDAL) - A new report from the Minnesota Department of Natural Resources has concluded that an Asian Carp barrier using sound, bubbles and lights would be the most viable option to deter the invasive fish from moving past Lock and Dam #1 on the Mississippi River in Minneapolis. The goal is to prevent the fish from using the locks to gain access to the upper reaches of the river which connects to other rivers and lakes in the state. The estimated costs of such a system would be about 12 million dollars but could go higher depending on the final design and construction.
