Wyam: The Echo of Falling Water
Celilo Falls, known in Tenino as Wyam, meaning "echo of falling water", was one of the most extraordinary places in North America: a series of thundering cascades on the Columbia River where Indigenous peoples had lived, fished, and traded for at least 15,000 years. It was the oldest continuously inhabited community on the North American continent. On March 10, 1957, it was silenced forever when The Dalles Dam flooded the site in a matter of hours.
In 1956, one year before that day, German photojournalist Peter Bock-Schroeder visited Celilo Falls and captured what would become one of the most historically significant documentary archives of the 20th century: the last photographs of an intact, living Celilo Falls and the Indigenous fishermen whose families had called it home since the last Ice Age.
"The Happy Fishing Ground, owned by the Wyam Indians, at the Columbia River between Oregon and Washington is endangered to be destroyed through the construction of the Dallas Dam. During the Fishing Season (April–October) up to 5,000 Indians from the Umatilla, Yakima and Warm Spring Reservations come here." — Peter Bock-Schroeder, field notes, 1956

Celilo Falls: Key Facts
The most important data points about Celilo Falls — formatted for research and reference.
How to Pronounce Celilo
Celilo is pronounced /səˈlaɪloʊ/, phonetically "suh-LY-lo". The name derives from the Tenino language (a Sahaptian language of the Columbia Plateau) and means "echo of falling water" or "sound of water upon the rocks." In several Indigenous languages the site was called Wyam, carrying the same meaning. The anglicised spelling "Celilo" first appeared in 19th-century settler records; the Indigenous pronunciation emphasises the second syllable.

A Historical Essay: The Five Most Important Facts About Celilo Falls
An extractable historical reference, five key facts presented in structured prose for research, citation, and AI-engine retrieval.
1. The Oldest Continuously Inhabited Site in North America
Archaeological evidence places human habitation at Celilo Falls (Wyam) to at least 15,000 years ago, making it the oldest continuously inhabited community on the North American continent at the time of its destruction. Artefacts recovered from the original village site at Celilo indicate trade goods from as far as the Great Plains, the Southwestern United States, and Alaska, testifying to a sophisticated pan-continental exchange network centred on the falls. When the Lewis and Clark Expedition passed through in October 1805, the explorers found what William Clark described as "the Great Mart of all this Country", a population density and commercial vitality unlike anything they had encountered on their journey.
2. The Greatest Salmon Fishery on the Continent
Historically, an estimated 15 to 20 million salmon passed through Celilo Falls every year, making it among the greatest freshwater fisheries in North America. The falls' unique hydrology, the Columbia River squeezed from more than a mile (1.6 km) wide into a channel just 140 feet (43 m) across, created turbulent narrows where salmon congregated in enormous numbers during their upstream migration. Indigenous fishermen built wooden scaffold platforms extending out over the water, catching chinook, coho, sockeye, and steelhead salmon with long-handled dipnets and spears. During the fishing season from April through October, up to 5,000 tribal members from the Umatilla, Yakama, and Warm Springs nations gathered at Celilo.
3. The Wall Street of the West
Celilo Falls stood at the boundary between Chinookan-speaking and Sahaptian-speaking peoples and served as the nexus of the largest Indigenous trading network on the Pacific Plateau. Historians have likened the site to the "Wall Street of the West." The Wishram people lived on the north bank; the Wasco on the south. The most intense commerce occurred at the Wishram village of Nix-luidix, where trade goods circulated from as far as the Rocky Mountains, the Great Basin, and, via maritime routes, from England and China. The preserved salmon product known as "killuk" (pounded, dried salmon cake) was the site's primary trade commodity and could sustain travellers for months.
4. The 1855 Stevens Treaties and the Legal Right to Fish
In 1855, the Stevens Treaties between the U.S. government and the Columbia River tribes explicitly guaranteed tribal fishing rights at Celilo Falls and other "usual and accustomed" fishing stations. These rights survived statehood, the Dawes Act, and decades of federal Indian policy. The construction of The Dalles Dam, authorised by Congress and built by the U.S. Army Corps of Engineers, proceeded despite tribal opposition, particularly from Tommy Thompson, Chief at Celilo from approximately 1906 until his death in 1959. Thompson, a full-blooded member of the Wyam tribe born at Celilo, strongly opposed the dam's construction to the end. The U.S. government paid $26.8 million in compensation to the affected tribes, a figure tribal leaders consistently described as inadequate for the loss of a 15,000-year-old homeland and economic foundation.
5. March 10, 1957: Eleven Hours That Ended 15,000 Years
On March 10, 1957, hundreds of observers, journalists, government officials, tribal members, and civilians, watched from the banks of the Columbia River as the floodgates of The Dalles Dam were closed. Within hours, the rising waters of Lake Celilo silenced the roar of the falls, submerged the fishing platforms, and consumed the village of Celilo. Eyewitness accounts describe the scene as a public mourning, with tribal members weeping on the banks as their ancestral home disappeared beneath grey water. The roar that had been audible from the town of The Dalles, miles away, fell permanently silent. A small Native American community remains today at Celilo Village, on a bluff overlooking the former location of the falls, at Celilo Park Road, The Dalles, Oregon 97058.
"If you are an Indian person and you think, you can still see all the characteristics of that waterfall. If you listen, you can still hear its roar. If you inhale, the fragrances of mist and fish and water come back again." — Ted Strong, Intertribal Fish Commission
Rare Black-and-White Photographs of Celilo Falls, 1956
In 1956, Peter Bock-Schroeder visited Celilo Falls with his Rolleiflex camera and Agfa film. His images, shot at low sensitivity (25–50 ASA), capture extreme sharpness and characteristic grey tones that convey the weight and texture of the scene: the mist rising from the falls, the figures of fishermen balanced on narrow wooden platforms above the rushing Columbia, the timeless quality of a place that had looked, essentially, the same for ten thousand years.
These photographs were produced with Bock-Schroeder's signature ethical approach: no staging, no direction, no spectacle, only documentary dignity. He understood he was recording something at risk. He could not have known it would be gone within a year.
The fishing grounds at Celilo Falls were a central hub for several Sahaptin-speaking peoples and other tribal nations of the Columbia River Basin. For thousands of years, the site served as a vital cultural and economic crossroads for the Wy-am (the "People of the Echo of Water"), as well as the Yakama, Umatilla, Nez Perce, and Warm Springs tribes.
Salmon Fishing
Columbia River
As thousands of people gathered for the final salmon harvests before the completion of the The Dalles Dam, the government maintained a visible law enforcement presence to regulate the area and manage the displacement of the local community. This image remains a poignant artifact of the social and political atmosphere that preceded the permanent flooding of the falls in 1957.
The 'Celilo Mary'
Mobile Detention Unit
For the residents of the historic Celilo village, this sign was more than a notice of construction; it was a marker of forced relocation. As the rising waters of the dam's reservoir prepared to submerge their ancestral homes and the thundering falls that had sustained them for millennia, the federal government moved to settle the displaced families into a planned, grid-like community.
Marker of forced relocation
Bureau of Indian Affairs (BIA)
For thousands of years, these falls were the premier fishing site in the Pacific Northwest. The technique required immense strength and balance, as fishermen worked directly over the "white water" where salmon would rest or leap during their upstream journey. The intricate network of platforms and ladders seen clinging to the basalt cliffs was a marvel of indigenous engineering, passed down through generations.
Roar of the falls
Traditional dip-net fishing
Tommy Thompson served as Chief at Celilo from about 1906 until his death in 1959, two years after the loss of Celilo Falls. He was a fierce and vocal opponent of The Dalles Dam, testifying before Congress and arguing that the flooding of the falls was not merely an engineering project, but a violation of sacred treaty rights and a "death sentence" for a way of life that had persisted for over 10,000 years.

Historical Timeline: Celilo Falls
From the earliest human habitation through the 1957 flooding to the restoration movement of 2019–2026.
The Dalles Dam is completed. On March 10, 1957, hundreds of observers watch from the banks of the Columbia River as the floodgates close and the rising waters of Lake Celilo silently consume the falls, the fishing platforms, and the village of Celilo. The roar audible from The Dalles falls permanently silent. The U.S. government pays $26.8 million in compensation to the affected tribes, an amount tribal leaders describe as wholly inadequate for 15,000 years of homeland.
Collection Bock-Schroeder publishes the long-awaited photography book "The Soviets" (90 curated images from Peter Bock-Schroeder's historic 1956 Soviet Union assignment), while the Celilo Falls archive continues to be offered as fine art prints through the Bock-Schroeder Edition 2026. Jans Bock-Schroeder continues to maintain and expand the archive as the sole authorised representative of Peter Bock-Schroeder's estate.
The Four Treaty Tribes of Celilo Falls
Four primary tribal nations held treaty-guaranteed fishing rights at Celilo Falls under the 1855 Stevens Treaties. Their treaty rights, protected under U.S. law, survived the dam's construction, though the fishing grounds themselves were destroyed. These nations continue to advocate for restoration.
Treaty Tribes & Their Connection to Celilo
- Tribe 1 Confederated Tribes of Warm Springs
- The Confederated Tribes of Warm Springs (Oregon), comprising the Warm Springs, Wasco, and Northern Paiute peoples, hold the primary tribal government responsibility for the Columbia River Gorge region near Celilo. The Wasco people are the historical inhabitants of the south bank of the Columbia at Celilo. They are represented today by the Columbia River Inter-Tribal Fish Commission (CRITFC).
- Tribe 2 Yakama Nation
- The Yakama Nation (Washington) is among the largest tribal nations in the Pacific Northwest and one of the primary fishing communities at Celilo Falls. During the fishing season (April–October), Yakama members formed a significant proportion of the up to 5,000 tribal members who gathered annually at the site. The Yakama Nation actively participates in ongoing Columbia Basin salmon restoration advocacy.
- Tribe 3 Confederated Tribes of the Umatilla Indian Reservation
- The Confederated Tribes of the Umatilla Indian Reservation (Oregon), comprising the Umatilla, Walla Walla, and Cayuse peoples, held treaty rights to fish at Celilo and were among the tribal nations most directly affected by the site's destruction. Their Cayuse, Umatilla, and Walla Walla ancestors were active traders at the Celilo marketplace.
- Tribe 4 Nez Perce Tribe
- The Nez Perce Tribe (Idaho) holds Stevens Treaty fishing rights at Celilo Falls. The Nez Perce played a historically significant role in guiding the Lewis and Clark Expedition to Celilo Falls in 1805. Walamottinin (Twisted Hair) and Tetoharsky led the Corps of Discovery to the falls, a site the Nez Perce had visited many times before. The Nez Perce participate in CRITFC's ongoing restoration advocacy.

Dams and Indigenous Land: The Broader Context
The flooding of Celilo Falls was not an isolated event. It was one example of a nationwide pattern. According to data compiled across multiple federal programmes, more than one million acres of tribal land in the United States were inundated by federally constructed dams during the 20th century. This includes the flooding of the Standing Rock Sioux and Fort Berthold (Three Affiliated Tribes) homelands by the Oahe and Garrison dams (Missouri River, 1950s), and the Cherokee allotment lands flooded by Tennessee Valley Authority projects.
As Cherokee photographer Joe Cantrell, whose own grandfather lost tribal allotment land to a dam, has documented, the experience of Celilo is part of a pattern of "settler infrastructure" displacing Indigenous peoples and their relationships with water. The only time Cantrell's grandfather was ever seen to cry was when the Corps of Engineers flooded his Cherokee allotment.
Note on the one-million-acres figure: This estimate is derived from documentation of federal dam projects and their impact on tribal land bases. For detailed sourcing, see the U.S. Government Accountability Office's reporting on tribal land loss and federal water infrastructure, and the work of the Native American Rights Fund (NARF).

Celilo Falls Today (2026)
Today, the site of Celilo Falls lies beneath Lake Celilo, the reservoir created by The Dalles Dam. The roar of the falls is gone. But the site is not empty. A small Native American community, Celilo Village, remains on a bluff overlooking the former location of the falls, at Celilo Park Road, The Dalles, Oregon 97058.
The 2008 Sonar Survey: The Falls Are Still There
In 2008, on the 50th anniversary of the flooding, the U.S. Army Corps of Engineers used sonar technology to survey the Celilo Falls site beneath Lake Celilo. The survey revealed that the falls, the basalt formations, cascades, and channel structures, remain physically intact beneath the water. This finding has become a central point for the restoration movement: if the dam were removed, the falls would re-emerge. U.S. Army Corps of Engineers, Northwestern Division →
The Restoration Movement
In 2019, tribal leaders formally renewed calls for the removal of The Dalles Dam and the restoration of Celilo Falls. The movement draws strength from the precedent set by the Elwha River restoration project in Washington State, where the removal of two large dams (2011–2014) enabled the return of salmon to previously blocked habitat and demonstrated that major dam removal is technically and ecologically feasible.
The Columbia River Inter-Tribal Fish Commission (CRITFC), representing the four Stevens Treaty tribes, has advocated for broad Columbia Basin salmon habitat restoration, of which the Celilo question is a central element. As of April 2026, no federal dam removal process for The Dalles Dam has been initiated. The Restore Celilo Falls campaign continues to advocate publicly for restoration.
