Yellow Grass is in a region of Canada known as the Great Plains, and situated well into the Canadian Prairies. The area is generally flat, but provides land suitable for large-scale farming. A few small, intermittent lakes populate the surrounding area. These lakes form as a result of the spring runoff when the snow melts, and vary in size depending on annual rainfall. In hot, dry years, some lakes can completely disappear, as no streams or rivers drain into the lakes.
