Its volume is about 137.9 cubic kilometers of water.

The shape is an annular lake surrounding René-Levasseur Island.

René-Levasseur Island has Mount Babel as its highest point.

Mount Babel rises 590 meters above the reservoir's water level.

The crater formed 214 million years ago in the Late Triassic.

A meteorite roughly 5 kilometers wide caused the crater's formation.

The crater's original diameter was about 100 kilometers across.

Erosion has reduced its visible diameter to about 72 kilometers.

Mount Babel is the crater's central peak formed by uplift.
