Numerous reports of unusually thick green algae have prompted the Metropolitan Water Reclamation District of Greater Chicago (MWRD) to begin seasonal water quality and habitat testing on Peregrine Lake in Palatine.
MWRD owns a majority of the lake, and staff aquatic biologists began the testing earlier this month. They will return to the lake during the summer and fall to complete their analysis. The MWRD routinely monitors waterways such as small streams, creeks, rivers and the canals.
