Toponym

The place name has been known for over a century. It refers to its position East of Lake Sainte Anne, an important water body in this border region in the neighboring municipality of Sainte-Perpétue, Chaudière-Appalaches, Quebec. Another name appeared in 1944 on the Township map: Lake Kijemquispam, presumably a Mi'kmaq place name.

The place name "Lac de l’Est " (English: Eastern Lake) was formalized on December 5, 1968, by the Commission de toponymie du Québec (English: Quebec Places Names Board).

Economical activities

This is the logging of the Highlands in Kamouraska that brought people to stand at the head of the lake (northern part). In 1894, the first sawmill is opened by a contractor from New Brunswick, who did the log drive logs toward Saint John River. A winter hamlet quickly developed, serviced by a post office as of 1898. Other mills have succeeded, activity peaking towards 1930 when 300 people permanently living there.

Later, we started to designate this hamlet by the name of Eatonville, but the name of "Lac de l’Est" (English: Eastern Lake) remained. After the 1960, cutting wood decreased and camps of lumberjacks were replaced by cottages, vacationers attracted by a large beach along the lake.
