The Skagit River (/ˈskædʒᵻt/SKAJ-it) is a river in southwestern British Columbia in Canada and northwestern Washington in the United States, approximately 150 mi (240 km) long. The river and its tributaries drain an area of 1.7 million acres (6900 km²) of the Cascade Range along the northern end of Puget Sound and flows into the sound.
The Skagit watershed is characterized by a temperate, mid-latitude, maritime climate. Temperatures range widely throughout the watershed. Recorded temperatures at Newhalem range from a low of −6 °F (−21 °C) to a high of 109 °F (43 °C), with greater extremes likely in the mountains. The highest temperatures are commonly recorded in July; the lowest are in January.
