Pasqua Lake is a lake along the course of the Qu'Appelle River in the Canadian province of Saskatchewan. Pasqua Lake was named after Chief Joseph Pasqua who formed what became the Pasqua First Nation. It is one of four lakes that make up the Fishing Lakes, which are all in the Qu'Appelle Valley. The Qu'Appelle Valley was formed about 14,000 years ago during the last ice age as meltwater from the glaciers carved out the valley. 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 Fishing Lakes, also called the Calling Lakes or the Qu'Appelle Lakes, are a chain of four lakes in the Qu'Appelle Valley cottage country about 40 miles (64 km) to the north-east of Regina in the Canadian province of Saskatchewan. The lakes are in a region called the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states. It is also within Palliser's Triangle and the Great Plains ecoregion. The Fishing Lakes all follow the course of the Qu'Appelle River, which flows from the west to the east and is part of the Hudson Bay drainage basin. The lakes sit in the deep-cut Qu'Appelle Valley that 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.
