GBA Flipping Book - Spring 2020

I n 2019, the entire Great Lakes Basin experienced high water levels. There was extensive flooding, erosion, and damage to shoreline infrastructure. Many residential and business shoreline properties were severely impacted – some were even destroyed, with at least one house toppling off a cliff on Lake Michigan. Every lake exceeded its historical record high in some months: ≥ Lakes Superior and Erie went over their record highs from May to September; ≥ Lake Ontario from May to August; and ≥ Lake Michigan-Huron in only one month – December. So where are we going from here? Analysis of past long-term water level fluctuations used to provide fairly accurate short-term predictions, but climate change impacts are making it impossible to depend on historical trends to predict the future. Regardless, we can draw some inferences about what to expect this spring and summer from the available information. Over the last several months, most predictions showed that Georgian Bay water levels would start 2020 around 11 inches higher than on January 1, 2019. In actual fact, we started the year at 16 inches higher.  Vol. 30 No. 1, Spring 2020 GBA Coastal Protection Initiative Flows from Review of Municipalities.......................................5 How Will TC Energy’s Pumped Storage Project Impact Georgian Bay?.......................................8 ED’s Advocacy Report.......................10 Upcoming Events...............................11 President’s Message..........................14 News and I nformat i on f rom the Georg i an Bay Assoc i at i on Asian Carp: Preventing a Threat to Great Lakes Fishing PAGE 6 PAGE 12 PM # 40038178 GBA U P D A T E Your Voice on the Bay The Big and Very Tiny Problem With Dock Foam Higher Water Levels in 2020?
