Cypress Lake (Saskatchewan)
Cypress Lake is the source of the Frenchman River and, being an interbasin reservoir, it supplies water to both the Frenchman River and Battle Creek watersheds. Frenchman River begins at Dam One on the eastern end of the lake while an outlet canal from Dam Two on the western end supplies water to Battle Creek.
Irrigation project
The building of the two dams of Cypress Lake were part of a larger project to bring stability to the water levels of Battle Creek as during the summer months, Battle Creek would often run dry. In 1936, near the headwaters of Battle Creek in the Cypress Hills, a dam was built along Adams Creek – a tributary of Battle Creek – that created Adams Lake (49°39′30″N 109°50′44″W / 49.6582°N 109.8455°W). During the dry months, water could be released from Adams Lake to help prevent Battle Creek from dying up, which allowed for irrigation throughout the growing season. With plans originally conceived in 1908, Cypress Lake was also turned into a reservoir in the late 1930s.
In 1937, contracts were handed out to several different companies to build various parts of the reservoir project at Cypress Lake, such as the building of Dam One at the east end of the lake, Dam Two at the west end, supply canals, outlet canals, the concrete structure, and the gravel facing for the earthen dams. Water for Cypress lake is supplied by diverting water from Belanger, Battle, and Sucker Creeks. Like Adams Lake, water from Cypress Lake is stored and then released during the dry season.
