Lac la Nonne is a lake in central Alberta, Canada. It is located between Lac Ste. Anne County and the County of Barrhead No. 11, 85 km north-west from Edmonton, east of the Grizzly Trail.
The lake is located within the Athabasca River basin and is fed by Majeau Creek, with water levels controlled by a dam, on the outflowing MacDonald Creek which then flows into the Pembina River.
Lac la Nonne is fairly large (11.8 km2) and deep (maximum depth 19.8 m) lake located about 90 km northwest of Edmonton in the counties of Barrhead and Lac Ste. Anne. This is a highly developed and popular recreational lake. The closest large population centre is the town of Barrhead, 20 km to the north. The name of the lake, "the nun" in French, has an uncertain origin. In 1827, Edward Ermatinger recorded the lake's name in his journal as Lac La Nane. It has been suggested that the name comes from the white-winged scoter, a duck with features similar to ducks in England known as "the nun".
The Hudson's Bay Company established a trading post at the lake in the early 19th century; by the 1830s there were many Métis, and by the 1870s a Catholic mission had been established. In the 1890s several families had settled around the lake, and by 1912 most of the available land had been homesteaded.
The Atlas of Alberta Lakes has this to say about the history of Lac LaNonne:
The Hudson's Bay Company established a trading post at Lac la Nonne in the early 1800s. The post was used to pasture the herds of pack horses needed to portage goods from Edmonton House to Fort Assiniboine on the Athabasca River (Edm. Reg. Plan. Commis. and Alta. Mun. Aff. 1980). By the 1830s, there were considerable numbers of Métis living by the lake. Missionaries arrived in the 1870s, and in 1878, the Oblate Fathers established a mission on the southeast shore at the site of the present-day Catholic Church in Camp Encounter. When the fur trade declined, the Métis moved away and the trading post and mission were closed (Barrhead Dist. Hist. Soc. 1967).
