Lac Ecluse is located in the municipality of Val-des-Monts, Quebec. The lake covers approximately 1.2 km2 with a  maximum depth of 43m.

Lakes are classified by their trophic status. Oligotrophic lakes are low in nutrients and hence are characterized by low plant productivity. Eutrophic lakes are high in nutrients and have high productivity. Eutrophic lakes can suffer from excess algae which can be toxic and reduces the oxygen available for other organisms in the lake. The trophic status of a lake is determined by measuring transparency, phosphorus, and chlorophyll A.
