Southwest Oregon's Klamath River Basin was the site of the nation's first waterfowl refuge, declared by President Roosevelt in 1908. Now, a move to protect aquatic life in the Klamath region is the cause of heated dispute among locals and has led the City of Klamath Falls to sue the US federal government for withholding irrigation water. Earlier this year, US Fish and Wildlife ruled that this summer's diversion of water from the Klamath River would threaten the continued existence of the endangered suckerfish and threatened coho salmon. This ruling, upheld by a federal judge, led the Bureau of Reclamation to withhold irrigation water from more than 1,400 farms. On July 4, a large group protesting this move cut open an irrigation headgate on the Klamath River. Also in the fray are people reliant on the fish -- the Klamath Tribes of Oregon and commercial fishers.
