Saskatchewan (/səˈskætʃ(ə)wən/ sə-SKATCH-(ə)-wən; Canadian French: [saskatʃəwan]) is a province in Western Canada, bordered on the west by Alberta, on the north by the Northwest Territories, on the east by Manitoba, to the northeast by Nunavut, and to the south by the United States (Montana and North Dakota). Saskatchewan and Alberta are the only landlocked provinces of Canada. In 2023, Saskatchewan’s population was estimated at 1,225,493. Nearly 10% of Saskatchewan’s total area of 651,900 km2 (251,700 sq mi) is fresh water, mostly rivers, reservoirs, and lakes.
- Drainage basin (Wikipedia)
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern.
