The Nooksack River is a river in the northwest part of the U.S. state of Washington. It drains an area of the Cascade Range around Mount Baker, near the Canada–US border. The lower river flows through a fertile agricultural area before emptying into Bellingham Bay and, via the Strait of Juan de Fuca and the Strait of Georgia, the Pacific Ocean. The river begins in three main forks, the North Fork, Middle Fork, and South Fork. The North Fork is sometimes considered the main river. Including the North Fork, the Nooksack is approximately 75 miles (121 km) long. All three forks originate in the Mount Baker Wilderness.
