Lake Quality Studies

The Maceday Lotus Lakes Association (MLLA) contracted for the first lake quality study just 4 years after the Association was incorporated.  Wallace E. Fusilier, Ph.D. of Water Quality Investigators performed the first water quality study in 1990 (see 1991 reports).  Follow-on studies were performed in 2000 and 2010 (see 1990-2000 reports). 

Restorative Lake Sciences was engaged to perform the 2015 lake quality study (see Maceday and Lotus Lake Study and Management Report 2015).

MLLA has participated in the Cooperative Lakes Monitoring Program (CLMP) since 2015 (except 2020 when the CLMP did not have funding). The purpose of the CLMP is to help citizen volunteers monitor indicators of water quality in their lakes and document changes in lake quality.  The latest report (2019) is provided here.  The 2020 report will be available in the winter 2022.  See [link] for more information about the CLMP.

Lake Water Level

The water level of Maceday and Lotus Lakes is controlled by a water level control structure on Van Norman Lake.  The Oakland County Water Resources Commissioner manages 54 lakes that have a legally established normal level.  This means there is a court order stating the normal level of the lake and designating the Water Resources Commissioner as the delegated authority to maintain the level.  Maceday and Lotus are grouped with Greens, Lester and Van Norman lakes (“Van Norman (WML)”).  There are three lake level control technicians who monitor the lake levels and perform the day-to-day operation of the structures.  More information as well as the weekly lake level reports can be found at
