Bass Lake is a shallow, warm-water mesotrophic lake in Oro-Medonte Township, Simcoe County, Ontario, Canada. The lake has a surface area of 5.5 square kilometres, an average depth of 3.5 metres and a maximum depth of 10 metres. It forms part of the North River watershed that drains into Severn Sound.[1][2]
Geography
It is fed by a combination of groundwater and several inflowing streams, both permanent and intermittent. Its 11-kilometre shoreline has areas of both natural vegetation and residential development. A small stop-log dam at the northwest outlet regulates water levels, which are typically higher in spring and fall.[3]
History
The lake basin originated from the recession of glacial Lake Algonquin approximately 10,000 years ago; a segment of the ancient shoreline bluff remains visible within the provincial park. European agricultural settlement reached the shores in the 19th century. The Province of Ontario acquired the land in 1956 and opened Bass Lake Provincial Park as a recreational facility in 1957.[4]
Ecology
The lake is classified as mesotrophic. Long-term monitoring shows it has a fair-to-good water clarity that has increased following the arrival of invasive zebra mussels, and moderate chlorophyll-a levels.
The fish includes smallmouth bass, largemouth bass, yellow perch, pumpkinseed, rock bass, black crappie, brown bullhead, white sucker and common shiner.[3][5]
