The Salcha drains an area of 2,170 square miles (5,620 km2), making it the second-largest tributary of the Tanana.[5] The Trans-Alaska Pipeline crosses under the Salcha approximately 12 miles (19 km) east of the mouth of the river.[4]
Recreation
Accessible by boat or on foot from the Richardson Highway, which crosses the lower river near the mouth, the Salcha River is a popular sports-fishing stream. The main species are king salmon, caught mostly near the mouth, and Arctic grayling, caught mostly further upstream.[6]
The Salcha River State Recreation Site is next to the Salcha River at milepost 323.3 of the Richardson Highway. The Alaska Division of Parks and Outdoor Recreation manages the 61-acre (25 ha) site, about 40 miles (64 km) southeast of Fairbanks. Amenities include six campsites, water, toilets, picnic sites, a boat launch, and a public-use cabin. Cross-country skiing and snowmobiling are among the possible winter activities near the site.[7] The park is known to be crowded on holiday weekends.[8]
