West Hawk Lake is one of the most popular sport diving sites in Manitoba, in fact anyone reading this article will probably admit to having "sat in the tub" off of Cat's Ass at least once in their diving lives. All divers have come to know West Hawk Lake for it's tremendous maximum depth. Some of your undeed may know that the West Hawk Lake basin is in fact a metorite impact structure. For those of you who are not aware of this fact, and even those who are, here is a brief geological history regarding the formation of West Hawk Lake.
The lake today covers a total area of 3,685 acres, with a maximum length and width of 7.2 kilometers and 4.8 kilometers respectively. The maximum depth of the lake is approximately 110 meters in the sediment-water interface. The lake basin was formed approximately 150 million years ago, during a period of geoological time known as the Jurassic Period, by the impact of a meteorite. The meteorite itself was approximately 150 meters in diameter and was probably composed of iron. The tremendous explosion force of the impact has been estimated as being equivalent to that of 25 Megaton blast.
The resulting crater was subsequently eroded and modified by the scouring action of glacial ice, which retreated from South-Eastern Manitoba approximately 11,000 years ago. Meltwater from the retreating ice filled the crater forming what we now know as West Hawk Lake.
