Lac Couture is a lake in Northern Quebec, Canada. It is located near Hudson Bay in the Kativik territory. The lake is approximately 150 meters deep.[https://ui.adsabs.harvard.edu/abs/1964AJ.....69R.134B/abstract Evidence Suggesting a Meteorite Impact Origin for Lac Couture, Quebec.] Beals, C. S.; Dence, M. R.; Cohen, A. J., Astronomical Journal, Vol. 69, p. 134 (1964)
Most of the lake covers an 8 km in diameter impact crater. The crater is estimated to be 430 ± 25 million years old (Silurian).{{cite Earth Impact DB | name = Couture | accessdate = 2009-08-13}} Breccia, suggesting impact origin, is present in boulders at the surface on islands around the perimeter of the lake. There is also a 25-meter central uplift in the lake floor, suggesting complex crater morphology.Flamini E., Coletta A., Battagliere M.L., Virelli M.
