The lake is named for Thomas McKay, one of the founders of Ottawa, who once owned all of Rockcliffe Park in the 19th century, including the lake.

Today, the west side of the lake is lined with mansions, and a public path known as the "Dog Walk", a closed portion of Lansdowne Road, while the east side of the lake is home to the Caldwell-Carver Conservation Area. The lake is drained by an intermittent stream that travels north into the Ottawa River. Its watershed includes the nearby Beechwood Cemetery and the next-door Sand Pits Lake, better known as "The Pond". The lake is fed by an intermittent stream that flows into the lake from the southeast.
