“Of primary concern are the Silver and Bighead carp which have been expanding their habitats within the Mississippi River basin for at least the past twenty years where they have decimated native fish populations by as much as 97 percent in some areas. These fish are currently threatening to enter the Great Lakes, a valuable fresh water resource.” THIS is the specific location they are able to cross from the Mississippi via the Wabash to the Great Lakes via the St. Marys/Maumee.
Proposed Interim Measures:
Inspect and increase/reinforce existing berm as necessary.
Fencing from Graham McCulloch Ditch berm to railroad embankment
Place mesh grates at the ends of underground conduits or cover the openings on both ends with large rock to allow water to flow through but impede fish passage.
Potential Long‐Term Measures:
Potential for a physical separation measure with a water level control structure located within or to the west of Eagle Marsh.
Potential fortification of Huntington Dam.
Save Maumee remains concerned about the lack of any plan, IF the Asian Carp DO make it into the Great Lakes. We are unaware of any reports, hypotheses or theories; what is the educated guess, as to the plan, if the Asian Carp are IN Lake Erie?
