Река Дельта: Путь от диких озер к стремительным порогам

River in the United States of America
In 1980, 62 mile (100 km) of waterways in the Delta River basin, including all of the Tangle Lakes and the main stem to within 0.5 mile (1 km) of Black Rapids became part of the National Wild and Scenic Rivers System. Of this, 20 mile (32 km) are designated "wild", 24 mile (39 km) "scenic", and 18 mile (29 km) "recreational".

Easily accessible from the boat launch at the Tangle Lakes campground near the Denali Highway and at many points downstream along the Richardson Highway, the river can be floated in sections that vary in difficulty from Class I (easy) to Class V (extremely difficult) on the International Scale of River Difficulty and may require portages. The upstream stretches include four lakes and their Class II (medium) connecting channels. About 2 mile (3 km) downstream of the last lake, the river enters a canyon and flows over unrunnable waterfalls. A 0.5 mile (1 km) portage leads to a 2 mile (3 km) stretch of Class III (difficult) rapids. Below the Class III rapids, the river continues through 29 mile (47 km) of Class I and II water before entering a 20 mile (32 km) stretch between Ann Creek and One Mile Creek known as Black Rapids. Here the difficulty is Class III rising to Class IV (very difficult) or V, followed by 30 mile (48 km) of Class III and then 18 mile (29 km) of Class I. In the deeper lakes of the system, lake trout are fairly abundant. Lakes and streams that are away from the highway and accessible only by canoe or trail are the least heavily fished. Arctic grayling fishing is also considered excellent on the upper river down to its confluence with Eureka Creek.
