ELECTRIC FISH BARRIER READY TO PROTECT IOWA GREAT LAKES
SPIRIT LAKE, Iowa - The electric fish barrier that will keep Asian carp from entering the Iowa Great Lakes through the Lower Gar Lake outlet is in place and operational. All that remains to be completed for the nearly $1 million project is final site restoration. Mike Hawkins, fisheries biologist with the Iowa Department of Natural Resources, said if a high water threat arose, they could activate the barrier to prevent invasive fish from entering the Iowa Great Lakes from downstream. “Invasive species seem unstoppable and are negatively impacting aquatic resources across the nation. This is an example of coming together as a community to win an important battle against them,” Hawkins said. “The electric fish barrier is currently the only effective tool to prevent upstream migration in this case.” Electric barriers are superior to physical barriers because they do not obstruct water flow or collect debris. The system creates an electrical field in the water th...
