" It is the longest free flowing river in the United States."[edit]
I don't see a reference for this statement, but the Yukon, for one, is longer and, to my knowledge, completely free-flowing as well. Perhaps the author if this sentence excludes the Yukon because it isn't entirely in the US? Terry Thorgaard (talk) 20:04, 31 December 2014 (UTC)
Correction: the article on the Yukon River indicates that There [is] a dam across the river ... The construction of the dam flooded the White Horse Rapids, which gave the city [of Whitehorse] its name, and created Schwatka Lake." Thus, it seems, the Yukon isn't completely free-flowing.
