Location and Geography
Cold Lake is a large lake located in eastern Alberta, Canada. It is situated approximately 190 kilometers northeast of Edmonton, the capital city of Alberta, and about 120 kilometers south of the provincial boundary with Saskatchewan.
The lake’s surface elevation is around 479 meters above sea level, making it one of the largest lakes in Alberta by area and volume. Its maximum depth reaches up coldlakecasino.ca to 35 meters, providing a relatively stable water environment for aquatic life.
Geological Formation
Cold Lake is situated within the Cold Lake Glacial Lake Bed Plains ecoregion, which comprises the lake’s basin, surrounding hills, and low-lying areas. The region experienced significant glacial activity during the last ice age (Pleistocene epoch), resulting in the formation of numerous lakes, including Cold Lake.
Glaciers carved out the present-day lake bed and formed numerous islands within the lake. Post-glacial rebound has caused ongoing changes to the lake’s shoreline, as evident from the varied types of shorelines found around the lake.
Water Characteristics
Cold Lake is a dimictic lake, with two distinct water-mixing periods occurring throughout its annual cycle. Water temperature varies significantly between spring and summer. In spring, temperatures rise slowly due to reduced ice cover, while in summer, they quickly warm up as sunlight intensifies.
The lake’s average water hardness measures around 150 milligrams per liter (mg/L), making it slightly alkaline in nature. Cold Lake has a relatively low total suspended solids concentration of approximately 0.5 mg/L, contributing to its clear and calm appearance.
Aquatic Life
Cold Lake is home to a diverse range of aquatic life due to its unique geological features. The lake supports both resident and migratory fish populations. Some notable species found in the lake include:
- Fish: Walleye, Whitefish, Yellow Perch, Northern Pike
- Crustaceans: Fathead minnows, Shad, Crawdads
These inhabitants play a crucial role in maintaining the aquatic food web and influencing water quality.
Human Settlement and Economy
Several First Nations communities have resided near Cold Lake for thousands of years. These communities include:
- Cold Lake First Nations (including Cold Lake Cree First Nation and Stoney Nakoda First Nation)
- Woodland Cree
- Ahtahkakoop
In the late 19th century, non-Indigenous settlers arrived in the area, attracted by its natural resources and economic opportunities.
The surrounding regions are primarily agricultural areas with a focus on cattle farming and grain production. Oil exploration activities have increased significantly since the early 2000s due to Cold Lake’s large deposits of bitumen.
Infrastructure and Accessibility
Cold Lake is accessible through several major roads:
- Highway 28, which provides transportation connections between Cold Lake and nearby cities
- Highway 55 connects Cold Lake with Edmonton via the Trans-Canada Highway
Several regional airports offer charter flights for transporting people and goods. However, regular commercial air service options are limited due to the remote location of these airports.
Cold Lake has its own airport located at 4N5 near town. The nearby community of Lac La Biche also offers a smaller general aviation airport.
