Most of the lake covers an 8 km in diameter impact crater. The crater is estimated to be 430 ± 25 million years old (Silurian).<ref>Template:Cite Earth Impact DB</ref> Breccia, suggesting impact origin, is present in boulders at the surface on islands around the perimeter of the lake.<ref name=beals1964/> There is also a 25-meter central uplift in the lake floor, suggesting complex crater morphology.<ref>Flamini E., Coletta A., Battagliere M.L., Virelli M.
