[ARCHIVED] Raising of the Portage and Base Line Lake Level

Text " Rising of Portage and Base Line Lake Levels"

The lake level at Portage and Base Line Lakes will be raised beginning on March 28, 2022. The lakes will reach their legally established summer level of 851.54 feet above sea level by April 11, 2022. This date may alter due to weather conditions between March 28th and April 11th. 

Portage and Base Line lakes are located in Dexter and Webster Townships. The Lake Level District includes lands in both Washtenaw and Livingston County. Washtenaw County includes approximately 545 parcels in the assessment district.

The lake level is adjusted each year to enhance the recreational opportunities for residents. Each winter the lake level is lowered to reduce ice damage and erosion on the lakeshore.
