MI - Lakes Michigan-Huron water levels expected to reach summer peak in July 2020
Webinar will discuss options for shore protection/stabilization with expected erosion.
The US Army Corps of Engineers has released the official July 2020 water levels update which shows that Lakes Michigan-Huron water levels will peak during July at their highest recorded level since accurate records began in 1918. Michigan-Huron is forecast to peak 3 inches higher than the prior highest July record, which was set in 1986. The lakes are currently at about 582.22 feet in elevation versus the previous July monthly average record of 581.99 feet in 1986 – again the highest in 101 “July averages.” If you think you have never ever seen the lakes this high in July, you are correct!
With these record-high waters, even small storms can drive waves to erode beaches and infrastructure. Erosion is to be expected throughout Fall 2020. While there are no easy solutions and erosion is site specific due to wave direction, topography, and other factors, understanding coastal dynamics can help with awareness and planning as the shorelines can undergo tremendous changes.
What Can Be Done?
Michigan Sea Grant is pleased to host an evening webinar for tribal and municipal officials, Great Lakes shoreline property owners, and other interested persons to explain high-water wave dynamics and coastal engineering approaches. Great Lakes coastal engineering practitioner Margaret Boshek PE, from the integrated design firm SmithGroup, will lead the discussion.
