Lake Celilo.
Lake Celilo was the impounded pool on the Columbia River created by the construction of The Dalles Dam in 1957, inundating the historic Celilo Falls and adjacent riverine terraces near The Dalles and Wishram. The inundation transformed a series of rapids and falls—long central to trade, fishing, and navigation for the Warm Springs Tribe, Umatilla Tribe, and Yakama Nation—into a slackwater reservoir that reconfigured regional Columbia River Gorge landscapes and transportation networks including U.S. Route 97 and rail lines owned by Union Pacific Railroad.
Geography
Lake Celilo occupied a stretch of the Columbia River extending upstream from The Dalles Dam toward Bonneville Dam and bordered counties including Wasco County, Sherman County, and Klickitat County. The inundation covered islands, rapids, and terraces used seasonally by the Nez Perce, Warm Springs Tribe, Umatilla Tribe, Walla Walla Tribe, and Yakama Nation. The topography of the area before inundation featured basalt outcrops of the Columbia River Basalt and floodplain soils tied to prehistoric episodes such as the Missoula Floods. The site lay within the Pacific Northwest climatic zone influenced by the Cascade Range rain shadow and the Columbia Gorge National Scenic Area corridor.
History
The Celilo stretch was a major Indigenous trade and cultural center for millennia, linked to seasonal migrations, fishing platforms, and intertribal exchange involving the Chinookan peoples, Multnomah, Wasco, Wishram, Cathlamet, and Lower Chinook. Euro-American contact introduced fur trade posts such as Fort Vancouver, explorers including Lewis and Clark, and subsequent settlement tied to steamboat traffic and the Oregon Trail. Hydroelectric development propelled construction of Bonneville Dam and later The Dalles Dam as part of Columbia River Treaty-era aspirations and U.S. Bureau of Reclamation and U.S. Army Corps of Engineers projects. The 1957 closure of The Dalles Dam inundated Celilo Falls, prompting protests by tribal leaders such as Wapato Chief? and negotiations involving the United States Department of the Interior, Congress, and tribal sovereign entities; compensation and relocation efforts intersected with litigation and policy debates involving figures from Senate committees and regional governors such as Oregon Governors of the era.
Ecology and Environment
The transition from free-flowing rapids to slackwater habitat altered populations of anadromous fishes including sockeye salmon, chinook salmon, coho salmon, steelhead, and white sturgeon. The change affected riparian vegetation communities and wetlands that had supported waterfowl monitored by U.S. Fish and Wildlife Service and research by institutions like Oregon State University and University of Washington. Invasive species management has involved agencies such as the Bonneville Power Administration and U.S. Army Corps of Engineers working with tribal biologists from Confederated Tribes of the Umatilla Indian Reservation and academic partners at University of Idaho to study habitat restoration, fish passage, and impacts tied to hydroelectric dams and Columbia River salmon recovery programs overseen by the National Oceanic and Atmospheric Administration.
Hydrology and Water Management
Water levels in the Celilo pool were controlled by The Dalles Dam's spillways and navigation locks operated by the U.S. Army Corps of Engineers. Management balanced hydroelectric generation for operators like Bonneville Power Administration with navigation for barge traffic tied to ports such as Port of The Dalles and Port of Portland. Reservoir operations interacted with upstream storage projects including Grand Coulee Dam and coordinated flow regimes under institutions shaped by the Columbia River Basin compacts and federal statutes debated in United States Congress. Sediment transport, stratification, and thermal regimes were altered, affecting fish passage projects and proposals such as fish ladders and bypass systems supported by the Northwest Power and Conservation Council.
Recreation and Access
Post-inundation, the slackwater of Lake Celilo supported boating, commercial fishing, and recreational angling tied to guide services licensed by state agencies like the Oregon Department of Fish and Wildlife and Washington Department of Fish and Wildlife. Recreation sites and viewpoints near Catherine Creek and along Interstate 84 and U.S. Route 30 served tourists visiting the Columbia River Gorge National Scenic Area and landmarks such as Rowena Crest and Crown Point. Access improvements involved state parks and river ports, while riverine navigation linked to commodity transport for Port of Portland and agricultural exporters in the Columbia Basin Project.
Cultural Significance
The inundation of Celilo Falls erased a central ceremonial and economic locus for Indigenous nations who had operated fishing platforms and annual assemblies documented by ethnographers like Alfred Kroeber and Franz Boas. Oral histories and tribal governance bodies such as the Confederated Tribes and Bands of the Yakama Nation and Confederated Tribes of the Umatilla Indian Reservation emphasize treaty rights affirmed in cases like United States v. Winans and advocacy through organizations including the National Congress of American Indians and tribal cultural committees. Artists, writers, and filmmakers—ranging from members of the Northwest Film Center to authors published by University of Washington Press—have memorialized Celilo in works that engage with regional identity, legal history, and Indigenous resilience.
Infrastructure and Economic Impact
The creation of the pool facilitated expanded navigation for bulk commodities moved by barge to export hubs such as Port of Longview and Port of Vancouver USA, benefiting industries involved with the Wheat Belt and timber shipping tied to companies like Weyerhaeuser. Hydropower generation at The Dalles contributed to regional grids managed by Bonneville Power Administration powering municipalities including Portland and Seattle and industrial facilities such as aluminum smelters historically located in the Columbia River Gorge corridor. Economic tradeoffs included lost Indigenous fisheries and tourist sites offset by jobs in construction, operations, and port logistics, with ongoing policy discussions involving agencies like the Federal Energy Regulatory Commission and regional economic development councils.
