Hanalei River
The Hanalei River on the island of Kauai in Hawaii flows north from the eastern slopes of Mount Waialeale for until it reaches the Pacific Ocean at Hanalei Bay as an estuary. With a long-term mean discharge of 216 cubic feet per second, in terms of water flow it is the second-largest river in the state; although its watershed of is only sixth-largest on Kauai, it encompasses areas of the highest recorded rainfall on the planet and plunges precipitously from its headwaters at above sea level.
The lower, flatter portion of the river flows by Hanalei National Wildlife Refuge and many taro farms. The Hanalei River provides habitat for a number of amphidromous species, including gobies, two native species of crustacean, the hīhīwai, and in its upper reaches, a threatened species of highly adapted snail.
The Hanalei was designated an American Heritage River by US President Bill Clinton on July 30, 1998.
The major bridge across the river is on Hawaii Route 560, which is listed on the National Register of Historic Places listings in Hawaii.
