Rising Water Levels in Great Lakes? ... or "When will the beach under my cottage erode into Lake Michigan?"
Posted by ZachDeCook on 3 October 2021 in English.Was doing some mapping, and noticed the shoreline in OSM didn’t line up with the latest aerial photos… By like 50 meters.
Doing some spot checking around the great lakes, the other lakes seemed fine, except in a spot in Lake Huron, the water was about 25 meters more in shore.
I guess according to NOAA’s data, in 2020 Huron-Michigan had really high levels, and 2021 is going down (2 feet) almost halfway to the mean. So… maybe in 6 years, the water level will be back down, so no changes need to be made to the map.
