Topic: Klamath River

Overview April 24, 2014

Klamath River

The Klamath River flows 253 miles from Southern Oregon to the California coast, draining a basin of more than 15,000 square miles. The watershed and its fisheries have been the subject of negotiation since the 1860s negotiations that have intensified and continue to this day.

The river has provided irrigation to ag lands since the late 19th century. Agricultural development drained vast areas of wetlands on the periphery of Upper Klamath Lake and in upstream watersheds. Some of this drained acreage has been restored and is now managed primarily for wetland benefits.

The watershed is divided geographically into two basins, upper and lower, divided by Iron Gate Dam, the lower most dam on the river. The Upper Basin is dry, with annual precipitation of about 13 inches at the river’s origin near Klamath Falls, Ore. Downstream, the climate grows wetter.

Native Americans have a significant presence in the Klamath Basin. Four major tribes have been influential in water negotiations: the Klamath Tribes, the Karuk Tribe, the Hoopa Valley Tribe and the Yurok Tribe.

Wildfire causes major damage to infrastructure at Mono Lake natural reserve

On the afternoon of May 22, a wildfire sparked next to Highway 395 near the Mono Lake Tufa State Natural Reserve in the Eastern Sierra Nevada, causing major damage to the reserve’s infrastructure. The Inn Fire took off quickly, fueled by high and erratic winds that caused it to jump across the highway, where flames burned into the reserve. … Officials are still assessing the extent of the damage caused by the Inn Fire. One home burned down soon after the fire ignited, and flames destroyed vegetation in the Inyo National Forest, burning up toward the mountains. In the state reserve, Jackson said flames burned into protected wetland habitat and around the tufas. But the tufas are undamaged, she noted. … The California State Parks Sierra District is working with local land managers and other partners to plan how to rebuild the boardwalk and the interpretative signs that were lost in the fire.

The river that came back to life: a journey down the reborn Klamath

… Last year, the final of four hydroelectric dams on the Klamath River were removed in the largest project of its kind in US history. Forged through the footprint of reservoirs that kept parts of the Klamath submerged for more than a century, the river that straddles the California-Oregon border has since been reborn. The dam removal marked the end of a decades-long campaign led by the Yurok, Karuk and Klamath tribes, along with a wide range of environmental NGOs and fishing advocacy groups, to convince owner PacifiCorp to let go of the ageing infrastructure. The immense undertaking also required buy-in from regulatory agencies, state and local governments, businesses and the communities that used to live along the shores of the bygone lakes. As the flows were released and the river found its way back to itself, a new chapter of recovery – complete with new challenges – emerged.

Land back: 47,097 acres returned to Yurok Tribe

The Yurok Tribe, California’s largest federally recognized tribal nation, was given 73 square miles of land — or 47,097 acres — along the eastern side of the lower Klamath River on Thursday. The land exchange is being called the largest single “land back” deal in California history. … The 73 square miles of land is now owned and managed by the Yurok Tribe as the Blue Creek Salmon Sanctuary and Yurok Tribal Community Forest. … These lands — comprising forests, river corridors, and prairies — support essential habitat for many imperiled species, including coho and Chinook salmon, marbled murrelets, northern spotted owls, and Humboldt martens. In the face of climate change, Blue Creek remains a crucial cold-water refuge for salmon, steelhead, and other native fish.

California’s Yurok Tribe gets back ancestral homelands

… Roughly 73 square miles (189 square kilometers) of homelands have been returned to the Yurok, more than doubling the tribe’s land holdings, according to a deal announced Thursday. Completion of the land-back conservation deal along the lower Klamath River — a partnership with Western Rivers Conservancy and other environmental groups — is being called the largest in California history. The Yurok Tribe had 90% of its territory taken during the California Gold Rush in the mid-1800s, suffering massacres and disease from settlers. … The Yurok people will now manage these lands and waterways. The tribe’s plans include reintroducing fire as a forest management tool, clearing lands for prairie restoration, removing invasive species and planting trees while providing work for some of the tribe’s more than 5,000 members and helping restore salmon and wildlife.

First Klamath River descent by Tribal youth begins June 12

The First Descent Expedition of the Klamath River by young members of Tribes living along the river will begin Thursday, June 12. Participants in the Ríos to Rivers Paddle Tribal Waters Program will lead the first-ever 30-day source-to-sea descent of the newly undammed Klamath River. An opening celebration marking the beginning of the month-long, 310-plus-miles expedition will be held June 12 at the headwaters of the Wood River, an invitation-only event. From the starting point, the kayakers will cross Upper Klamath Lake, portage around the Link River Dam, and cross Lake Ewauna to the Klamath River. … Organizers said the event will “explore the long-awaited return of Chinook salmon to their ancestral spawning grounds, the far-reaching benefits of dam removal and the revival of an entire ecosystem. Experts will share insights on water quality improvements, habitat restoration and the lasting impacts on wildlife and river communities.”

Illegal lamprey selling operation on Klamath River shut down by CDFW

A Placer County man is going to jail after the California Department of Fish and Wildlife busted an illegal fish selling operation. According to the CDFW, their Delta Bay Enhanced Enforcement Program and Special Operations Unit investigated a conspiracy to sell Pacific lamprey, leading to the arrest of Justin D. Lewis. Lewis sourced Pacific lamprey, a California state species of special concern, from the Klamath River in Del Norte County and resold the fish to sellers across Colusa County and beyond. The CDFW said lamprey are often used as bait for sturgeon and other fish, but also are valued highly by the Yurok tribe in Del Norte County as a food source and cultural emblem.  Lewis was sentenced on May 21 to two years — one in the Colusa County Jail, and another on supervised release. He also must pay more than $20,000 in fines and his fishing privileges are suspended.

NOAA cuts threaten salmon and steelhead restoration work

Recent cuts to the National Oceanic and Atmospheric Administration (NOAA) have conservationists and scientists worried about anadromous fish populations in the Pacific Northwest. Like other federal agencies, NOAA is undergoing major downsizing. The shrinkage is already disrupting habitat restoration work for salmon and steelhead in California. And if additional budget cuts that are currently in the works come to fruition, the agency’s fisheries division could be eliminated entirely, a recently retired NOAA scientist tells Field & Stream. … When it comes to salmon and steelhead, (fluvial geomorphologist Brian) Cluer worries most about the potential loss of dam-removal projects in the Pacific Northwest. NOAA played a pivotal role in the removal of four dams on California’s Klamath River in 2023 and 2024, Cluer says.

New access sites open on undammed Klamath River. Just beware the white water

New public access sites have opened along the post-dam Klamath River, allowing opportunities to enjoy the free-flowing river. The largest dam removal project in U.S. history was completed last year along the Klamath River. Proponents wanted the dams gone to restore native salmon populations and important cultural sites for the Shasta Indian Nation. But the undamming project has also added new recreational opportunities on the free-flowing river. Three sites opened this week in Oregon and California, where visitors can put in boats, part of the Klamath River Renewal Corporation’s recreation plan. American Whitewater, a recreation advocacy group, has helped with the process. … This week, the Pioneer Park West site opened in Oregon. In California, the Copco Valley (K’utárawáx·u or ), Fall Creek (K’účasčas) and Iron Gate locations have also opened.

Klamath River opens for visitors after nation’s largest dam removal project

With the recent completion of dam removal along the California-Oregon border, the public is being invited in to see the results. A string of new recreation sites on the Klamath River began opening Thursday, allowing visitors to view and access the free-flowing waters that Native Americans and environmentalists had long pushed to undam. The five river access sites remain in various stages of development. Three are debuting this week with pit toilets, boat ramps, patches of riverfront and not much else. Improved facilities are expected in coming months, providing sparse but scenic spots for picnicking, wildlife viewing and kayaking. Two of the sites are still under construction and are closed. Managers of the dam-removal project expect all the access areas to be fully open by August.

News release: Assembly passes AB 263 to protect Klamath River salmon flows

On Monday, AB 263 overwhelmingly passed the state Assembly. The bill protects salmon populations in two key tributaries of the Klamath River watershed by keeping minimum flow requirements in place until the State Water Board can establish new long-term flow regulations. The bill is now headed to the state Senate for their consideration. … AB 263 was introduced in partnership with the Karuk Tribe, California Coastkeeper Alliance, and the Pacific Coast Federation of Fishermen’s Association (PCFFA). The bill would maintain river flows for at-risk salmon runs on two critical Klamath River tributaries – the Scott and Shasta Rivers.

Opinion: A surge of salmon – and hope – after Klamath dams’ removal

Last year, we watched as the last of four dams were removed from the Klamath River in a historic endeavor. Karuk and Yurok citizens sighed in relief, grateful that decades of tribal-led activism, scientific research and litigation had succeeded in reopening 400 stream miles of spawning habitat for salmon and other species. The tears of joy came just a few weeks later, when research cameras showed the first of more than 6,000 fish traveling past the first dam site. Spawning salmon were crossing into Oregon’s Spencer Creek, a tributary of the Klamath, for the first time in 112 years. The salmon had remembered the way, for it is embedded into their DNA just as it is in our ancestors’ – a testament of shared memory and spiritual connection between our people and the river.
–Written by Russell “Buster” Attebery, chairman of the Karuk Tribe, and Joseph L. James, chairman of the Yurok Tribe.

Promising signs for 2026 after California closes commercial salmon season for the year

For the third consecutive year, commercial salmon fishing off the California coast will be prohibited, although there will be a limited opportunity for recreational anglers for the first time since 2022. However, officials say data indicates the industry could see a return in 2026. Angela Forristall, salmon staff officer with the Pacific Fishery Management Council, said the decision to recommend closing the state’s commercial salmon fisheries for the year followed a challenging debate among the council and stakeholders from both the recreational and commercial fishing industries. Forristall shared that there were several versions of the recommendation that did open commercial fishing briefly, but the data they’re seeing from populations in the Klamath and Sacramento rivers says it’s potentially too soon for major operations.

Klamath dam removals: Loss of Copco Lake leaves some residents reeling

The dam removal projects- aimed at sustaining the salmon population, are underway, with the latest drawdown being three reservoirs on the Klamath River. The removal process has already dramatically changed the landscape in Southern Oregon and far Northern California, along the course of the river. The lowest of the three remaining dams- Iron Gate, was initially breached on January 9, followed by the J.C. Boyle reservoir on January 16. A concrete plug in the tunnel at the base of Copco 1 was blasted away on January 23, with the reservoirs draining quickly, leaving vast expanses of fissured mud that was the consistency and color of chocolate cake batter. Shaping its new course, the Klamath River is winding through the bare landscape, but the transformation has had some unintended consequences and saddened some residents.

State limits water for Klamath farmers to protect salmon

…Tuesday, the State Water Resources Control Board took action to protect the salmon, unanimously extending the region’s expired emergency drought measures. Ground and surface water for farms will be restricted for another year if flows in the Shasta and Scott rivers dip below minimum thresholds. State officials say these measures are likely to kick in next year. Water board chair Joaquin Esquivel said action is needed because “a fish emergency” remains on the rivers. “Time isn’t our friend,” he said at a previous meeting in August. “There is an urgency.” The water board also is investigating the possibility of permanent requirements to keep more water in the rivers, after the Karuk Tribe and the fishing industry petitioned the state for stronger protections. That decision, however, could take years.

Understanding Streamflow Is Vital to Water Management in California, But Gaps In Data Exist
WESTERN WATER NOTEBOOK: A new law aims to reactivate dormant stream gauges to aid in flood protection, water forecasting

Stream gauges gather important metrics such as  depth, flow (described as cubic feet per second) and temperature.  This gauge near downtown Sacramento measures water depth.California is chock full of rivers and creeks, yet the state’s network of stream gauges has significant gaps that limit real-time tracking of how much water is flowing downstream, information that is vital for flood protection, forecasting water supplies and knowing what the future might bring.

That network of stream gauges got a big boost Sept. 30 with the signing of SB 19. Authored by Sen. Bill Dodd (D-Napa), the law requires the state to develop a stream gauge deployment plan, focusing on reactivating existing gauges that have been offline for lack of funding and other reasons. Nearly half of California’s stream gauges are dormant.

WESTERN WATER NOTEBOOK: Pumping near the Scott River in Siskiyou County sparks appellate court ruling extending public trust doctrine to groundwater connected to rivers

Scott River, in Siskiyou County. In 1983, a landmark California Supreme Court ruling extended the public trust doctrine to tributary creeks that feed Mono Lake, which is a navigable water body even though the creeks themselves were not. The ruling marked a dramatic shift in water law and forced Los Angeles to cut back its take of water from those creeks in the Eastern Sierra to preserve the lake.

Now, a state appellate court has for the first time extended that same public trust doctrine to groundwater that feeds a navigable river, in this case the Scott River flowing through a picturesque valley of farms and alfalfa in Siskiyou County in the northern reaches of California.

Pacific Flyway

Sacramento National Wildlife RefugeThe Pacific Flyway is one of four major North American migration routes for birds, especially waterbirds, and stretches from Alaska in the north to Patagonia in South America.

Each year, birds follow ancestral patterns as they travel the flyway on their annual north-south migration. Along the way, they need stopover sites such as wetlands with suitable habitat and food supplies. In California, 95 percent of historic wetlands have been lost, yet the Central Valley hosts some of the world’s largest populations of wintering birds.

Klamath River Basin

Cropland around Upper Klamath Lake in Oregon

The Klamath River Basin is one of the West’s most important and contentious watersheds.

The watershed is known for its peculiar geography straddling California and Oregon. Unlike many western rivers, the Klamath does not originate in snowcapped mountains but rather on a volcanic plateau. 

A broad patchwork of spring-fed streams and rivers in south-central Oregon drains into Upper Klamath Lake and down into Lake Ewauna in the city of Klamath Falls. The outflow from Ewauna marks the beginning of the 263-mile Klamath River.

The Klamath courses south through the steep Cascade Range and west along the rugged Siskiyou Mountains to a redwood-lined estuary on the Pacific Ocean just south of Crescent City, draining a watershed of 10 million acres. 

A bounty of resources – water, salmon, timber and minerals – and a wide range of users turned the remote region into a hotspot for economic development and multiparty water disputes (See Klamath River timeline).

Though the basin has only 115,000 residents, there is seldom enough water to go around. Droughts are common. The water scarcity inflames tensions between agricultural, environmental and tribal interests, namely the basin’s four major tribes: the Klamath Tribes, the Karuk, Hoopa Valley and Yurok. Klamath water-use conflicts routinely spill into courtrooms, state legislatures and Congress. 

In 2023, a historic removal of four powers dams on the river began, signaling hope for restoration of the river and its fish and easing tensions between competing water interests. In February 2024, Interior Secretary Deb Haaland announced a “historic” agreement between tribes and farmers in the basin over chronic water shortages. The deal called for a wide range of river and creek restoration work and modernization of agricultural water supply infrastructure. 

Water Development

Farmers and ranchers have drawn irrigation water from basin rivers and lakes since the late 1900s. Vast wetlands around Upper Klamath Lake and upstream were drained to grow crops. Some wetlands have been restored, primarily for migratory birds.

In 1905, the federal government authorized construction of the Klamath Project, a network of irrigation canals, storage reservoirs and hydroelectric dams to grow an agricultural economy in the mostly dry Upper Basin. The Project managed by the U.S. Bureau of Reclamation irrigates about 240,000 acres and supplies the Lower Klamath Lake and Tule Lake national wildlife refuges managed by the U.S. Fish and Wildlife Service.

Klamath River Basin

Water Management

Since 1992, federal mandates to restore populations of fish protected by the Endangered Species Act have led in some dry years to drastic cuts in water deliveries to Klamath Project irrigators.

Water in Upper Klamath Lake must be kept above certain levels for the endangered shortnose and Lost River suckers. Lake levels and Klamath River flows below Iron Gate Dam also must be regulated for the benefit of threatened coho salmon (See Klamath Basin Chinook and Coho Salmon).

Conflict

In 2001, Reclamation all but cut off irrigation water to hundreds of basin farmers and ranchers, citing a severe drought and legal obligations to protect imperiled fish. In response, thousands of farmers, ranchers and residents flocked to downtown Klamath Falls to form a “bucket brigade” protest, emptying buckets of water into the closed irrigation canal. The demonstrations stretched into the summer, with protestors forcing open the irrigation headgates on multiple occasions. Reclamation later released some water to help farmers.

Karuk fisheries workers netting salmon in Klamath River.In September 2002, a catastrophic disease outbreak in the lower Klamath River killed tens of thousands of ocean-going salmon. The Pacific Coast Federation of Fishermen’s Associations sued Reclamation, alleging the Klamath Project’s irrigation deliveries had violated the Endangered Species Act. The fishing industry eventually prevailed, and a federal court ordered an increase to minimum flows in the lower Klamath.

Compromise

The massive salmon kill and dramatic water shut-off set in motion a sweeping compromise between the basin’s many competing water interests: the Klamath Basin Restoration Agreement and the Klamath Hydroelectric Settlement Agreement. The 2010 agreements included:

  • Removal of four hydroelectric dams
  • $92.5 million over 10 years to pay farmers to use less water, increase reservoir storage and help pay for water conservation and groundwater management projects.
  • $47 million over 10 years to buy or lease water rights to increase flows for salmon recovery.

Dam Removals

Congress never funded the two agreements, allowing the key provisions to expire. The restoration accord dissolved in 2016. The hydroelectric pact, however, was revived in an amended version that did not require federal legislation.

The new deal led to the nation’s largest dam removal project ever undertaken.

The Klamath's Copco No. 2 DamCalifornia and Oregon formed a nonprofit organization called the Klamath River Renewal Corporation to take control of the four essentially obsolete power dams – J.C. Boyle, Copco No. 1, Copco No. 2 and Iron Gate – and oversee a $450 million dam demolition and river restoration project.

Taking out the dams will open more than 420 miles of river and spawning streams that had been blocked for more than a century, including cold water pools salmon and trout need to survive the warming climate.  

Demolition crews took out the smallest dam in 2023 and the others were scheduled to come down by the end of 2024.

The images of yellow heavy machinery tearing into the dam’s spillway gates prompted a cathartic release for many who have been fighting for decades to open this stretch of the Klamath.

“I’m still in a little bit of shock,” said Toz Soto, the Karuk fisheries program manager. “This is actually happening…It’s kind of like the dog that finally caught the car, except we’re chasing dam removal.”

Klamath Basin Water Quality

 Klamath Basin Water Quality

On the Klamath River, the Upper Klamath Basin’s aquatic ecosystems are naturally very productive due to its phosphorus-rich geology.

However, this high productivity makes the Basin’s lakes vulnerable to water quality problems.

Nutrient loads in the Upper Klamath Basin are a primary driver of water quality problems along the length of the Klamath River, including algal blooms in the Klamath Hydroelectric Project reservoirs. Municipal and industrial discharges of wastewater in the Klamath Falls area add to the nutrient load.

Klamath Basin Chinook and Coho Salmon

The Klamath Basin’s Chinook salmon and coho salmon serve a vital role in the watershed.

Together, they are key to the region’s water management, habitat restoration and fishing.

However, years of declining population have led to federally mandated salmon restoration plans—plans that complicate the diversion of Klamath water for agriculture and other uses.

The Klamath River Basin: A Microcosm of Water in the West
May/Jun 2000

The story of the Klamath River is the story of two basins.

In the upper basin, farming has long been the way of life. Even before passage of the 1902 Reclamation Act, settlers had begun the arduous process of reclaiming vast tracts of wetlands and transforming them into rich farmland.
