Mission Lake
Mission Lake, also known as Lebret Lake, is a lake in the Canadian province of Saskatchewan. It is one of four lakes along the Qu'Appelle River known as the Fishing Lakes. Echo Lake is upstream while Katepwa Lake is downstream. The lake was named 'Mission' after the Catholic mission at Lebret. Highways 22 35, and 56 provide access.
Mission Lake, as well as the other three Fishing Lakes, are all in the Qu'Appelle Valley, which was formed about 14,000 years ago during the last ice age. Meltwater from the glaciers carved out the valley and as water levels rose and fell, alluvium was left in the wake. These piles of alluvium are what created the separations between the lakes.
The Qu'Appelle River is both the primary inflow and out flow. The river enters the lake at the west end, near the town of Fort Qu'Appelle, and exits the lake at the south-east end. Echo Creek is a small creek that rises to the south-west near McLean and enters the lake at the south-west corner at Fort Qu'Appelle.
