The final water level reading of 2021 was 978.20' on November 22 (east bay gauge)
This can be compared to the Lowest level in recent records of 977.78' on August 10, 2007, the final reading last fall on November 8, 2020 of 978.38' and the Ordinary High Water Level for Sarah of 979.90'. Thank you to Cindy Keating (west bay) and the Spencer family (east bay) who continue to volunteer their time to monitor our lakes’ water levels for the MN DNR, LSIA, and our website for yet another year!

Ordinary High Water Level for Lake Sarah (27-0191) 979.90' (revised from 979.50' as of 10/13/2003 - Minnesota DNR OHWL study in.pdf) The ordinary high water level (OHWL) is a reference point that defines the DNR's regulatory authority over development projects that are proposed to alter the course, current, or cross section of public waters and public waters wetlands. For lakes and wetlands, the OHW is the highest water level that has been maintained for a sufficient period of time to leave evidence upon the landscape. The OHWL is commonly that point where the natural vegetation changes from predominately aquatic to predominantly terrestrial. For watercourses, the OHWL is the elevation of the top of the bank of the channel. For reservoirs and flowages, the OHWL is the operating elevation of the normal summer pool. The OHWL is also used by local units of government as a reference point from which to determine structure setbacks from water bodies and watercourses. See also legal definition under Hydrographics Program. For more information on determining OHWL please see "Guidelines for Ordinary High Water Level (OHWL) Determinations".

A special thank you to Cindy Keating and Fred Lang for providing the water level readings for the MN DNR, the lake association, and to this website. Cindy monitors the primary gauge in the west bay, Fred monitors the backup gauge in the east bay.
Lake Level Minnesota is a program in which volunteers collect and report lake levels throughout our State.
