Theodore Reservoir

(Theodore Lake)

Theodore Reservoir is a medium-sized (737-acre), long, and narrow recreational and fishing lake along the course of the Whitesand River. The lake is 6km NE of Theodore and 38km NW of Yorkton. Good Spirit Lake and the provincial park are 30km to the West.

The water level on the reservoir has been lowered due to work on the dam and there are aerators in operation. Watch out for thin ice if you head out this winter!

Whitesand Regional Park is located at the lake and offers camping, a playground, a boat launch, and a 9-hole golf course.

There is another boat launch at the south end of the reservoir by the dam. The area by the dam also offers shore fishing opportunities.

The dam is accessible from Highway 726, while the regional park is accessible from Highway 651.

The lake is regularly stocked with Walleye, and Northern Pike and Perch can also be found.
