The Oldman River Basin is located in southern Alberta, Canada. It encompasses the area drained by the Oldman River and its tributaries, covering approximately 12,000 square kilometers. The basin is characterized by diverse landscapes, including mountains, foothills, and plains, which support various ecosystems and wildlife. The Oldman River originates in the Rocky Mountains and flows eastward, eventually joining the South Saskatchewan River. The basin is significant for agriculture, providing irrigation water to local farms, and is also important for recreational activities such as fishing and hiking. Conservation efforts are in place to protect its natural resources.
