Watershed/ River Valley

Accordion Answer

Wherever you live, you live in a watershed. A watershed is the area of land that carries water from the land after rain falls and snow melts through the soil, groundwater, creeks and streams making its way into larger rivers and eventually the ocean.

Watershed/River Valley
The Oldman River Watershed is located in the southwest corner of Southern Alberta. There is one city, Lethbridge, located within the watershed and several towns and hamlets that are home to approximately 200,000 people.

Each watershed is sub-divided into smaller sections. Below is a map which illustrates the four sub-basins that exist within the Oldman Watershed.
