Delta River

[5] 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.

About 2 miles (3 km) downstream of the last lake, the river enters a canyon and flows over unrunnable waterfalls.

[6] Author Karen Jettmar warns of dangers including "sweepers, canoe fragments wrapped around rocks, bears, cold and wet weather, and high winds".

"[6] The Tangle Lakes complex, 24 miles (39 km) long, that feeds the Delta River has "some of the best road-accessible grayling fishing in Interior Alaska".

Arctic grayling fishing is also considered excellent on the upper river down to its confluence with Eureka Creek.
