The Study has found a previously unrecognized 5.8% increase in the outflow from Lake Huron into the St. Clair River - equivalent to three times the amount of the Chicago diversion. Surely the IJC will recognize this as a breach of the Boundary Waters Treaty, the reason the IJC was formed in 1909. Analyzing the revised St. Clair River flow data provided by the Study Board, Sierra Club Ontario determined that 200cm/s flow was missing. That missing amount resulted in incorrect calculations and conclusions. In fact, the 5.8% increased flow in the St. Clair River is probably 10%. Lakes Michigan/Huron/Georgian Bay water levels have hovered near record lows for an unprecedented 13 years while Lakes St. Clair and Erie have been rising.

The Great Lakes have been experiencing shifting water levels over the past few decades as a result of dredging, mining, and shoreline alterations. In areas where Lakes are faced with lower levels, Cargo ships are struggling to deal with the changes. Avoiding simple solutions like decreasing cargo weight to accommodate lower lake levels, Obama has instead decided to channel 31 million dollars of the 2012 US budget towards dredging commercial harbours and navigation channels (Associated Press). This would save Cargo ships from cutting revenues by being able to keep cargo at a profitable weight. It is unfortunate that Obama is seeking hard-path solutions in dealing with water levels just as he has dedicated 350 million of the 2012 to Great Lakes environmental clean-up.

This report is a progress report on the research funded by Sierra Club carried out from May to October in 2011. The three main projects share an overarching theme that examines threats to coastal biodiversity because of changes in the hydrologic regime of Lakes Huron and Erie.
The first project provides an initial glimpse of how northern pike utilize wetland and nearshore habitat in Tadenac Bay and the surrounding region.
The second is a comparison of home ranges of the Blanding's turtle (species at risk) in two protected areas (Beausoleil Island of Georgian Bay Island National Park and Rondeau Bay Provincial Park) that have very different landscape features and experience different stresses. Since this is the first documented study of a Blanding's population on an island, a sub--‐project has been carried out to determine if turtles select for specific habitats before, during and after nesting as has been suggested by the literature.
The third project examines the effects of rain effects and agricultural practices on the water quality of first--‐order streams in the Beaver River watershed.
