From a month ago water levels on Lake Michigan-Huron are unchanged, Lakes Superior, St. Clair, and Erie are 4, 1 & 2 inches lower respectively, and Lake Ontario is up 2 inches. Lakes Superior, Michigan-Huron, St. Clair, Erie and Ontario are 1, 16, 9, 4 and 17 inches, respectively, above their levels of a year ago. In a month’s time all the Lakes are projected to be 3 to 4 inches lower. - Outflows from Lake Superior into the St. Mary’s River and Lake Michigan-Huron’s outflow into the St. Clair River are predicted to be above average for November. Lake St. Clair’s outflow through the Detroit River and Lake Erie’s outflow through the Niagara River are also forecasted to be above average in November. In addition, Lake Ontario’s outflow through the St. Lawrence
Warmer water temperatures are reducing the effectiveness of the chemical 3-trifluoromethyl-4-nitrophenol (TFM) to fight sea lamprey. TFM has been applied to streams since 1980 at an annual cost of over US $20 million and does not impact other aquatic life. Given that sea lampreys are probably the greatest threat to native fish species if uncontrolled, this is a major problem. GBA is currently monitoring the issue. Read more about the situation here. -
From a month ago, water levels on Lake Ontario are unchanged and Lakes Superior, Michigan-Huron, St. Clair, and Erie are 1, 1, 4 & 4 inches lower respectively. The lakes are 2 to 18 inches higher than they were at this time last year. In a month’s time, Lakes Superior, Michigan-Huron, St. Clair and Erie are projected to be 2 to 3 inches lower, while Lake Ontario is forecasted to fall 5 inches. Outflows from Lake Superior into the St. Mary’s River and Lake Michigan-Huron’s outflow into the St. Clair River are predicted to be above average for November. Lake St. Clair’s outflow through the Detroit River and Lake Erie’s outflow through the Niagara River are also forecasted to be above average in November. In addition, Lake Ontario’s outflow through the St. Lawrence River is
A conflict surrounding a proposed gravel pit development and a densely populated habitat for Blanding's turtles could be a major test of species protection in Ontario. This precious habitat for the endangered species is located in the township of North Shore on the North Channel of Lake Huron as noted on the map. The North Shore's municipal council is expected to approve rezoning of the area for mineral extraction. If approved, it will then be up to the province to make a decision between development or species protection. Read more about the situation here. GBA recently expressed concerns on the Provincial Policy Statement Review with regard to the removal of environmental safeguards in favour of new aggregate developments. Read the GBA submission here.
Bi-partisan support and the efforts of Georgian Bay Great Lakes Foundation (GBGLF) helped with the recent approval of U.S. federal government funding of $1 million to establish a grass carp population management program in the Great Lakes. Grass carp are one of the four invasive species know collectively as Asian carp, and are notorious for their voracious appetites. Read more about the program here.
The Provincial Policy Statement (PPS) sets out details for Ontario's land use and planning. The revisions proposed by the Ontario government included several reductions in environmental protections in favour of development and business interests. GBA therefore submitted comments on a range of topics including aggregates extraction, wetlands protection, climate change directives, sewage systems, and flexibility for municipalities to address local planning issues. See the GBA submission here: GBA online ERO submission 019-0279 PPS Oct 21 2019
On October 25, 2019, the Ontario government announced it will not impose any municipal realignment in the province, but instead will work with municipalities to improve their effectiveness and efficiency. GBA is posting this update on the status of the municipal review issue and on GBA’s actions relating to municipal structures on the east coast of the Bay since the government’s initial announcement of its review last year. Also posted are several reports and papers issued over the years since GBA’s first involvement with the issue more than 40 years ago.

From a month ago water levels on Lakes Superior and Michigan-Huron are the same, Lakes St. Clair, Erie, and Ontario are 3, 4, and 4 inches lower respectively. The lakes are 4 to 18 inches higher than they were at this time last year. Over the next month Lake Ontario is expected to be unchanged, and Lakes Superior, Michigan-Huron, St. Clair and Erie are projected to each decline 3, 2, 4, and 3 inches, respectively. Outflow from Lake Superior into the St. Mary’s River is forecasted to be above average for November. Lake Michigan-Huron’s outflow through the St. Clair River and Lake St. Clair’s outflow through the Detroit River are also projected to be above average in November. Moreover, Lake Erie’s outflow through the Niagara River and Lake Ontario’s outflow through the St. Lawr

On Saturday October 19th Georgian Bay Association (GBA) and Georgian Bay Forever (GBF) jointly hosted H20 2019 at Ryerson University. Over 100 people came out to the event and were treated to a plethora of topical information delivered by our dynamic speakers. The presentations provided many great takeaways on: climate change impacts on high water levels and water quality; municipal overflows and other climate change impacts on municipal structures; the state of private septic systems in Ontario and Georgian Bay and how to look after yours; the current status of the seasonal hydro rate class and background to electricity pricing; the ins and outs of solar systems for your cottages; and the financial and environmental advantages of switching to an electric car. The pr
The proposed Macey Bay trailer park, located off Honey Harbour Road in the Township of Georgian Bay, is in the midst of some significant and ecologically important Georgian Bay wetlands and extensive habitat for species at risk. GBA has made a submission under the Environmental Bill of Rights that addresses each of the components of the project, together with some general comments.

New York State has finally launched their long threatened lawsuit against the International Joint Commission (IJC) claiming that the IJC has caused the flooding there in recent years (read the rationale behind the lawsuit here). However the science does not appear to support their contentions. GBA has worked closely with the IJC for most of our 103 year history and we value our strong relationship with them. Our interpretation of the science is that precipitation levels and evaporation are the main drivers of changing water levels. Almost all evaporation occurs in the cold months whenever there is little or no ice cover, and the water temperature is higher than the air temperature. Flow rates between the lakes and down the St Lawrence have a limited impact, which is particularly apparen
