Pink Lake is located in Gatineau Park, Quebec, Canada, just north of Ottawa.
It is named after the Pink Family, who were Irish immigrants of the early 1800's. Pink Lake is thought to be a meromictic lake which is one that lacks complete cirrculation. The lake
is approximately 162m above sea level. It has a maximum depth of 20m, which is very deep for its small size of 9 hectares. A small stream flows into Pink Lake from the north, and the
lake drains east to the Gatineau River. Pink Lake was once part of the Champlain sea, being isolated from it about 11,000 years ago. Since this time the lake has undergone a gradual process of freshening as fresh water enters the lake.
