Title: Water quality summary for the inland lakes of Grey and Bruce Counties
Author: Water Resources Assessment Unit, Technical Support Section, Southwestern Region
Abstract: The majority of inland lakes contained within the Southwestern Region of the Ministry of the Environment are-found in Grey and Bruce counties. These lakes are small, shallow, hardwater lakes that are sensitive, primarily because of their size, to influences that affect their water quality. Little change has been noticed however in the productivity of these lakes as reflected through long-term monitoring of water clarity and phytoplankton from 1972 to 1981. Intermittently, however, their sensitivity has been demonstrated through peaks in phytoplankton growth which have resulted in documented blooms on twenty-five percent of the 28 lakes monitored. In addition, several lakes support extensive growths of rooted plants in the nearshore areas which have been a source of concern to users. Over the period of record, water quality has generally been good enough to support a variety of recreational uses.
