Site description Chaplin Lake is situated in south central Saskatchewan, near the town of Chaplin. It is a large saline lake approximately 35 km in length and up to 10 km wide (after the Quill Lakes, it is the second largest saline lake in Canada). The lake is divided into four sections by a series of dykes and roads that were constructed as part of a sodium sulphate mine development on the north shore. Extensive marshes are located in the southern half of the lake. Water levels fluctuate considerably, with extensive mudflats becoming exposed during the late spring and summer; during some years the lake may become completely dry by mid-summer.
