The report, the product of a multi-year, congressionally-ordered Great Lakes and Mississippi River Interbasin Study, presented alternatives ranging from continuing current efforts (apparently no pun intended — electrical current is being used to deter fish passage) to complete physical separation of the waters. Implementation of some alternatives could take 25 years, at costs of up to $18-billion-plus.
