Site description Metiskow and Sunken lakes are two small shallow lakes in central eastern Alberta. Metiskow Lake (an unofficial name for an unnamed lake) is just north of the community of Metiskow, while Sunken Lake is to the south. The town of Provost is about 30 km to the east. These lakes are permanent hyper-saline lakes surrounded by native sandy aspen parkland and some cultivated land. The 10 and 30 m wide beaches where Piping Plovers nest on Metiskow Lake have extensive alkali deposits and soft muddy patches, and the isolated gravelly beaches of Sunken Lake are over 30 m wide. Sunken Lake is so named because it sits in a local depression. Scratch grass (Muhlenbergia asperifolia), a rare plant in Alberta, occurs at this site. This is one of only a few (approximately 6-20) occurrences in the province.
