Spring 2021 Update:

Thanks to the great response from our Sage Lake Property owners with the emails sent to Hill Township in fall of 2020, plus the efforts of the Sage Lake Association Board of Directors and Aquatic Plant Management Committee (Weed Control Committee), the Aquatic plant control (weed control) for 2021 will be managed by PLM.  PLM is a lake and land management corporation who manages over 100 other lakes in Northern Michigan.  Just to name a few in our area are Houghton Lake, Long Lake, Loon Lake, George Lake, and Rifle Lake.  PLM will listen to the recommendations from the DNR study in 2019 and Restorative Lake Sciences (RLS) who SLA recently hired as an independent lake consulting company.  Please read the 2019 PLM Presentation from the link below to learn more about this company.

Responsibilities of the Lake Maintenance Committee:

Dam Function: The dam committee maintains the lake level by raising and lowering the dam board. This is done in agreement with the Michigan DNR.  

Weed Control Committee: The Weed Control Committee is a group of residents on Sage Lake who work with the weed treatment provider and Sage Lake Board of Directors to reduce the nuisance weeds. Each member has been assigned a zone or area of the lake. If you have a question or concern about the weeds in your area, contact the Zone Rep from your zone. The table list the Committee members and their assigned zones.

The funding for weed control comes from tax payers in a special tax assessment district and is collected by Hill Township. The assessment is on each tax bill for an area around the lake. The area is called Sage Lake Assessment District (SAD).
