The Nooksack River is a 75-mile-long river in northwest Washington that flows through Whatcom County, eventually emptying into the Puget Sound. Historically, the river was used by local tribes for fishing and transportation. The river's hydrology is influenced by snow melt and rainfall, which can lead to flooding in the winter months. There are several reservoirs and dams along the river, including the Deming Dam and the Baker River Dam, which are used for hydroelectric power generation. The river is also used for recreational activities such as fishing, kayaking, and rafting, and supports agricultural uses such as irrigation for crops like blueberries and raspberries. The Nooksack River is an important natural resource for the region and is managed by various agencies to ensure its continued health and sustainability.
