You don't need an expert to tell you that the water level on Wall Lake and the surrounding lakes are probably setting record high levels. We have heard that Jim Dull, Barry County Drain Commissioner, has gotten the permits to do the culvert work on Shallow Lake and until that is done, don't expect the water level to go down very fast.
Michigan Lake and Stream Association did a webinar this spring about Michigan High Water. The presentation started with pictures of Lake Michigan and Lake Huron in 2013, a year that set an all time low water record for Lake Michigan and Lake Huron (they are treated as one body of water since they are connected and have the same water level within inches of each other). Then the presentation states that we have seen record high water levels the last few years. For 2020, we have set a new all time high level record each and every month this year that is predicted to continue into summer. There are many factors that influence the water level, but the one mostly responsible for the swing from low level to our current high levels is an increase is precipitation in the area. This increased precipitation has also caused the high water levels in nearly every inland lake and river in the state of Michigan.
The high water level greatly increases the possibility of shoreline erosion, so until the water level goes down, please be mindful of what wake you cause and where you are on the lake this summer.
