The Sumas River is a river that flows through two countries. It starts in the United States and then crosses into Canada. It is a tributary of the Fraser River. This means it is a smaller river that flows into a larger one.
Where the Sumas River Flows
The Sumas River begins in Whatcom County, Washington. This is a county in the United States. It starts near the Nooksack River and Sumas Mountain.
The river then flows mostly towards the northeast. It crosses the border between Canada and the United States. Finally, it flows into the big Fraser River in British Columbia.
A Special Creek: Swift Creek
One small stream that flows into the Sumas River is called Swift Creek. This creek carries natural rock material from a slow-moving Swift Creek Landslide. This material can make the water look cloudy.
The History of Sumas River
A long time ago, the Sumas River used to flow into a very large body of water. This was called Sumas Lake. It was a big lake located on the flat land near the Fraser River.
However, in the 1920s, people decided to drain the lake. This means they removed all the water from it. The land where the lake used to be is now dry land.
