The war on Asian carp and other invasive species could cost billions.
A report from the Great Lakes and Mississippi River Interbasin Study caps four years of work by a team headed by Dave Wethington. He says the options – which range from keeping the electric barriers in place but doing no more to build more than $15 billion worth of barriers between Lake Michigan and the rest of Illinois’ inland waterway system – are up to, in large part, the public.
“I wouldn’t say that, necessarily,” says Wethington. “The Great Lakes have … recovered from a series of invasive species, most recently being the zebra and the quagga mussels. (But some people) don’t want to take the chance” that the status quo is enough for the future.
A series of meetings in Great Lakes cities – including Chicago on Thursday – is part of a public comment period which ends March 3.
