Thomson Lake[1] is a reservoir in the Canadian province of Saskatchewan along the course of Wood River in the Old Wives Lake closed watershed.[2] The lake was created in 1958 for irrigation and consumption with the damming of Wood River. It was named after Dr Leonard Thomson who was the director of the Prairie Farm Rehabilitation Administration (PFRA) at the time.
Most of Thomson Lake is within the Rural Municipality of Wood River No. 74 while the northern tip is within the Rural Municipality of Gravelbourg No. 104. Thomson Lake Regional Park is located on the eastern shore of the lake and, other than the cabins at the park, there is one small cottage community on the lake called Gaumond Bay; it is located along a bay at the northern end of the lake. Lafleche, located along Lafleche Creek,[3] is the closest town at about 5 kilometres (3.1 mi) east of the southernmost point and the town of Gravelbourg is 9.7 kilometres (6.0 mi) north of the lake. Access to the lake is from Highway 58.[4][5]
