Whatcom County is located in the northwest portion of Washington State. It is bordered on the east by Okanogan County, the south by Skagit County and the southwest by San Juan County. As of the 2010 U.S. Census, Whatcom County had a total land area of 2,106.86 square miles and a population of 201,140. Bellingham is the largest city with a population of 80,885. Also of interest:
- Intersecting watershed sub-basins(6): Similkameen, Methow, Fraser, Strait of Georgia, Nooksack and Upper Skagit.
- Major lakes: Lake Whatcom, Baker Lake, Ross Lake and Samish Lake.
- Major rivers: Nooksack River, Baker River, Chilliwack River, Samish River and Skagit River.
- Mount Baker (10,781 feet) is part of the Cascade Range and the highest point in Whatcom County. It is also one of five major composit volcaonoes (sometimes called stratovolcanoes) located in Washington State.
Can restoring the natural balance of the Nooksack River also reduce flood risks? Officials on both sides of the U.S.-Canada border are taking note as climate change raises the stakes.
