Gow is an impact crater in Saskatchewan, Canada.
It is 5 km (3 mi) in diameter and the age is estimated to be less than 250 million years (Triassic or later). The crater contains a classic crater lake with an island (Calder Island) formed by the central uplift.[1][2] It is the smallest known crater in Canada with an uplift structure.[3]
The larger Deep Bay crater, of Cretaceous age, is approximately 90 km east of Gow crater.
