A lake lying at or near the foot of a glacier. [Lat. pro, in front + Fr. glace, ice.

A lake in front of a glacier, usually situated between the ice front and a terminal moraine.

a lake comprised of glacial melt water in front of a glacier.

A lake formed beyond the limits of a glacier, in front of a glacier terminus.

In geology, a proglacial lake is a lake formed either by the damming action of a moraine or ice dam during the retreat of a melting glacier, or one formed by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. At the end of the last ice age approximately 10,000 years ago, large proglacial lakes were a widespread feature in the northern hemisphere.
