The map and graph above show 9 profiles of Lake Montgomerie.
The lake had an area of 2847 square kilometers. The mean depth
was 291 meters, and the maximum depth was 690 meters.
This would bump the Great Slave Lake out of
sixth
place in the deepest lakes of the world.
The first five are Lake Baikal (1741m), Lake Tanganyika (1400m), Caspian Sea (1025m),
Lake Malawi (706m), and Lake Issyk-Kul in Kyrgyzstan (702m).
The deepest US lakes are Crater Lake (592m), Lake Tahoe (501m), and Lake Chelan (489m).
Based on the provisional SRTM 3" DEM, the lake had a volume of
835 cubic kilometers. The profiles imply that the lake has accumulated
hundreds of meters of sediment in 9000 years. On the other hand, the
canyon may have been partially scoured while the lake drained.
This graph shows how the lake would have filled with various configurations
of the ice dam. Terraces (below) suggesta lake at 3530 meters at 9000 years BP
and a lake at 3088 meters at 1200 years BP.
