So far this month, the entire Great Lakes Basin has received 111% of average precipitation, with Lakes Superior and Lakes Michigan Huron at 143% and 119% respectively. More precipitation occurred this weekend primarily in the eastern part of the basin. - Lake Michigan-Huron is 4 inches higher than one month ago, 7 inches above its level of last year, and is projected to continue its upward seasonal trend, climbing 4 inches over the next 30 days. - Lake Superior’s outflow through the St. Mary’s River, and Lake Michigan-Huron’s outflow into the St. Clair River, are forecasted to be above average in April. Moreover, the outflow of Lake St. Clair through the Detroit River is predicted to be above average. - The most recent clear satellite image is this one
Over the past week, temperatures have been warmer than average across the Great Lakes basin. Lake Michigan-Huron is 4 inches higher than it was a month ago, 4 inches above its level last year, and is projected to rise 3 inches over the next 30 days.

Our primary concern is that changes do not compromise the protection of Species at Risk (SARs) by relaxing regulations to favour industry and development, but instead focus on improving the Act and its regulations to assist SAR recovery, and deal with the shortfalls in implementation that have been evident since enaction in 1971. Georgian Bay is home to numerous SARs, so this matter is important to all of us. - GBA submission on 10 year review of the Endangered Species Act - Mar 4 2019Download
