Site description Hansman Lake is located approximately 10 km west of the town of Provost, in east-central Alberta. The lake is fairly alkaline with no emergent vegetation. Most of the land around the lake is cultivated.

Key Biodiversity Hansman Lake supports from 10,000 to 30,000 white geese each fall. Most of these geese are Snow Geese although some are Ross Geese. 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 5,000 Ross Geese are usually present in the spring and fall. A few thousand Greater White-fronted Geese are usually present each fall. There is very little use of the lake by ducks and swans.
