Final as approved by Sierra Club (US & Canada) on 5 December 2011
Whereas the Asian carp (bighead, silver, grass and black) have invaded extensive portions of the United States waters and the silver and bighead carps present a serious and immediate threat of invasion into the Great Lakes ecosystem, via the Chicago Sanitary and Ship Canal; and
Whereasthe Asian carp have caused ecological devastation in the Illinois and Mississippi River systems in specific river sections where they have become well established—95 percent of the biomass in some river sections is composed of Asian carp; and
Whereasthe Asian carp cause this devastation through highly efficient reproduction and filter feeding that effectively removes the plankton that serve as the base of the food chain—without enough plankton to support forage fish, shellfish and other species, native species decline ; and...

Sierra Club is the only grassroots environmental organization active in all Great Lakes jurisdictions. The Ontario Chapter and Sierra Club Chapters in all eight U.S. Great Lakes States support ecosystem-wide stewardship of Great Lakes levels. As well, Sierra Club Ontario now has the policy support of those US Chapters for the gradual restoration of Upper Great Lakes levels. Our Great Lakes Bi-national Policy simply and clearly now states:... Read more »
Great Lakes Section Chair Mary Muter was honoured earlier this year by the Township of the Archipelago "for her dedication and hard work in seeking solutions to the current problems facing the water quality and water levels of the Great Lakes." See more online here:
We're proud of you Mary!
Bill Bialkowski, an engineer with extensive professional expertise dealing with flow dynamics, reviews the International Joint Commission's summary of multi-lake management for the Great Lakes and poses some interesting questions.

IJC ’93 Level Reference Study Chapter 4
Note by Bill Bialkowski, 25 November, 2011,
The 1993 IJC Level Reference Study was the largest study ever conducted by the IJC on water levels ($20m). It came after two significant events. 1) The completion in 1977 of sill designs for the St. Clair River (SCR) to compensate for the dredging up to 1962, and 2) the 1974 high water followed by the record setting high water of 1986. This second event guaranteed that nothing would be done to compensate the SCR as Orders for Approval and funding were withdrawn. With the IUGLS’s 2009 ‘do nothing’ recommendation, and the flawed 2011 Restoration Report, some Georgian Bay people are claiming that the IUGLB is now ‘in favour’ of recommending multi lake regulation based on comments at public meetings....
