Boundary Dam Reservoir

Boundary Dam Reservoir is a medium sized reservoir in southern Saskatchewan along the course of Long Creek. It is connected to McDonald Lake through a 10km diversion channel that can take excess water in either direction between the reservoirs.

Boundary Dam Reservoir is located 10km SSW of Estevan with access from Highway 47.

A section of the Woodlawn Regional Park is located at the reservoir. There is a full-service campground, a beach, a boat launch, and volleyball courts.

Walleye, Largemouth Bass, Northern Pike, White Sucker and Yellow Perch can be found in Boundary Dam Reservoir. Reminder that there is a limit of 0 for largemoth bass here in Saskatchewan.

Largemouth Bass

Due to warm water being returned by the Boundary Dam Power Station, a large area of the reservoir doesn't freeze during the winter. This features allows Boundary Dam Reservoir to support a population of large mouth bass, making it the only lake in Saskatchewan that does.

The Boundary Dam was originally built in 1957 to create a reservoir to supply water to the Boundary Dam Power Station and the city of Estevan.

Fish Facts

Fish Facts 2023	Walleye (50-2425g) Northern Pike (31-1975g) Yellow Perch (35-465g)	July 10-13, 2023. Gill nets. No largemouth bass were caught due to limited susceptibility to gill nets.
Fish Facts 2013	Walleye: (90 - 1060 g) Good Perch: (60 - 290 g) Poor Bullhead: (300 - 750 g)	July 29 - 31 / Gill nets. Walleye are more abundant than encountered in previous surveys. Capture of small walleye suggests recent successful reproduction. Pike populations remain sparse, as none were captured during the survey.
