Great Slave Lake [1] [a] is the second-largest lake in the Northwest Territories of Canada (after Great Bear Lake), the deepest lake in North America at 614 m (2,014 ft), [2] and the tenth-largest lake in the world by area.
A reliable volume figure requires a bathymetric survey. [9] Therefore, mean depth figures are not available for many deep lakes in remote locations. [9] The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [9]
The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration . Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.

The lake has a surface area of 31,153 km 2 (12,028 sq mi) and a volume of 2,234 km 3 (536 cu mi). Its maximum depth is 446 m (1,463 ft) and average depth 71.7 m (235 ft).
Bathymetric surveys and charts are associated with the science of oceanography, particularly marine geology, and underwater engineering or other specialized purposes.

Daisy Lake is a lake in the Arctic Ocean and Great Slave Lake drainage basins in South Slave Region, Northwest Territories, Canada. [1]The lake is about 13.3 kilometres (8 mi) long and 2.3 kilometres (1 mi) wide, lies at an elevation of 356 metres (1,168 ft), and is located about 30 kilometres (19 mi) southeast of the settlement of Fort Reliance on McLeod Bay, the large easternmost bay of ...
The Yellowknife River is a river in the Northwest Territories, Canada.It flows south and empties into Yellowknife Bay just where it is crossed by the Ingraham Trail.It is part of Great Slave Lake, approximately 7.5 km (4.7 mi) north northeast of the city of Yellowknife.
Great Slave Lake is slightly smaller, with an area of 28,568 square kilometres (11,030 sq mi) and containing 2,088 cubic kilometres (501 cu mi) of water, although it is significantly deeper than Great Bear. [18] The third major lake, Athabasca, is less than a third that size with an area of 7,800 square kilometres (3,000 sq mi). [15]
