Site description St. Lawrence Lake is located approximately 15 km east of the town of Provost, in east-central Alberta. The lake is fairly alkaline and shallow, with no emergent vegetation. The lake fluctuates in size, being only half its normal size in the fall of 2000. The land around the land is mostly pastureland.

Key Biodiversity In the fall, St. Lawrence Lake supports from 10,000 to 30,000 white geese. Most of these birds are Snow Geese, but some are Ross Geese. The average number of 20,000 is a globally significant number. Ross Geese arrive earlier than the Snow Geese, which peak in early October, so these figures to not include peak Ross Goose numbers. About 2,000 to 4,000 Ross Geese are usually present in the spring and fall. Greater White-fronted Geese are also abundant between 5,000 and 10,000 are usually present. The higher number is about 1% of the North American population.
