Our History

David takes on goliath

Greater Hells Canyon Council was founded in 1967 (as Hells Canyon Preservation Council). It was the era of Big Dams; Idaho Power was planning to construct the High Mountain Sheep Dam, whose creation would have drowned the wild and magnificent Hells Canyon forever.


When a group of hiking buddies from Idaho Falls learned of the plans to dam Hells Canyon, they formed HCPC to save their beloved retreat. These hiking buddies happened to be nuclear physicists, and they arranged meetings with Idaho Power officials, coming armed with slide rules and detailed questions about the proposed dam—detailed enough that Idaho Power decided to call in their lawyers. (Read a wonderful short history on these first days here.)

HCPC then joined forces with a young lawyer from the Sierra Club, Brock Evans, who filed an injunction with the courts to temporarily hold the dam's construction at bay. To everyone’s surprise, the injunction worked! HCPC and its allies now had some breathing room to carefully consider what they wanted. Stopping the dam was not enough—they had a larger vision for a protected Hells Canyon, wild and free for animals, plants, and recreation.

After years of campaigning in Washington, DC and in Hells Canyon country, HCPC and its allies prevailed. On December 31, 1975, President Gerald Ford signed into law the Hells Canyon National Recreation Area Act.

The Federal Power Commission (FPC) grants a license to the Pacific Northwest Power Company (PNPC) to build the High Mountain Sheep Dam. Washington Public Power Supply System sues the FPC, arguing that the approval of a privately built dam is against public interest. 

The dam was proposed to be built one mile upstream from the confluence of the Snake and Salmon Rivers, and would have flooded both Hells Canyon and the Imnaha Canyon. Historic mock up of the High Mountain Sheep Dam courtesy of The Wallowa County Chieftain.

Russ Mager shows slides of the threatened Hells Canyon to the Idaho Alpine Club. A group of hiking buddings present decide to form the Hells Canyon Preservation Council.

The Sierra Club directs their newly appointed northwest representative Brock Evans to save the canyon from the dam.


The Supreme Court surprises everyone by remanding the High Mountain Sheep case back to the FPC, and questioning whether a dam should be built at all. Brock Evans files a petition to join the case as an intervener.


Evans and The Wilderness Society’s Clif Merritt meet with leaders of the newly formed HCPC at Willow Bar Camp in Hells Canyon. 

September 25: Evans’s petition is granted, making this the first time a case to preserve wilderness would be presented in a court. Evans and co-counsel Tom Brucker spend the next three years arguing their case in court.

Evans travels to Washington DC to advocate for a wild Snake River. A lucky connection earns him a meeting with the Undersecretary of the Interior. Within a month of this meeting, the Department of the Interior stops supporting new dam construction.

Photographer Boyd Norton gets a proposed “National River” bill and photos of Hells Canyon on Senator Robert Packwood’s (R-OR) desk. Packwood introduces the bill with 26 co-sponsors.

Representative John Saylor (R-PA) introduces a National River companion bill to Congress.


Boyd Norton invites radio and TV host Arthur Godfrey and the Associated Press, United Press, and CBS to Idaho boatman Floyd Harvey’s ranch. The press campaign to save the canyon has begun! Despite getting many decision makers into the canyon, little progress is made on moving the National River bill forward.

The Judge hearing the case re-issues the license to build the High Mountain Sheep Dam, but issues a three year moratorium on building, during which the conservationists could seek legislation from Congress.

Larry Williams, Joe Walicki, and Brock Evans testify before Congress.

Dale Jones of Friends of the Earth arranges a float trip with folk singers Jimmy Collier and Pete Seger to help raise public support for saving Hells Canyon.

Senator Frank Church (D-ID) formally renounces his previous pro-dam position and suggests Hells Canyon become a National Recreation Area.

HCPC President Pete Henault and Doug Scott of the Sierra Club work with congressional staff to draft a new bill that synthesizes the best of previously proposed bills, drafts, and strategy memos. The new bill provides for no dams; wild and scenic river status; and wilderness for the canyon walls on both sides of the river.

June 2: After months of delays, the Senate approves the “four Senators” bill, shifting the pressure onto Congress. Power interests attempt to introduce language into the congressional bill that would protect only the lower half of the river from dam building, but the bill is introduced to vote without these amendments.

November 12: Senate passes the Hells Canyon Bill.

November 18: House passes the Hells Canyon Bill.

December 31: Victory!!! President Gerald Ford signs the act to establish the Hells Canyon National Recreation Area in Oregon and Idaho, saving Hells Canyon from the High Mountain Sheep or any other dam, and designating over 200,000 acres of wilderness and 71 miles of river as wild.

-    Recognized again by the National Awards Council for Environmental Sustainability.


-    Inspired the U.S. Forest Service to implement the first ever jet-boat-free area on the Snake Wild and Scenic River.
