Commentary: Water is life. It’s also energy — whether you like dams or hate them

The rain and snow that have drenched California and much of the American West over the last few months — at least relative to some of the hellishly dry years we’ve gotten recently — are a blessing not just for water supplies, but for energy. Or maybe they’re a curse (for energy, not for water). It depends on whom you ask. Much of the electricity powering our lights and refrigerators and cellphones comes from rivers, their once free-flowing waters backing up behind dams and trickling through hydropower turbines.

Lake Spaulding powerhouse #1 offline after leak discovered

NID released a notice informing the public of cuts to the Bear River water flows yesterday afternoon. The district cited “unexpected maintenance work in the headwaters” in their release. We can now confirm a shutdown of PG&E’s Spaulding #1 powerhouse is the cause of what could be a prolonged outage in water flows. According to a PG&E spokesperson: During a routine inspection at PG&E’s Spaulding 1 powerhouse on March 6, a leak was discovered adjacent to a pressure relief valve. On March 7 a more detailed inspection was made of the PRV [pressure relief valve] and PG&E determined that repairs would need to be made before the powerhouse could be returned to service. The estimated return to service date is April 30.

Potter Valley Project decommissioning takes next step

The impacts to Lake County’s water supply were debated at the Board of Supervisors meeting February 27 with discussion centered over the substantial effects on the county’s future water supply if PG&E’s proposed plans are carried out in full. Consideration was made of: A. requesting a letter of support from the State Department of Water Resources, and B, approval of resolution authorizing the grant application, acceptance and execution of the Potter Valley Project de-commissioning. Such action means probable removal of Scott Dam and maybe elimination of Lake Pillsbury. Asking the Board chair to sign the letter was Matthew Rothstein, Chief Deputy County Administrative Officer along with Patrick Sullivan, treasure/ tax collector.

Federal data reveals a surprising drop in renewable power in 2023, as slow winds and drought took a toll

U.S. utility-scale renewable electricity generation fell in 2023 due to weather patterns that reduced output from wind farms and drought that affected hydropower. Data released by the Energy Information Administration shows a decrease of 0.8 percent compared to the prior year. This is a stunning result, considering that utility-scale renewables have been a fast-growing part of the electricity mix and are a crucial resource for the country’s transition away from fossil fuels. … Hydropower plants generated 239,855 gigawatt-hours, down 5.9 percent from 2022. The main reason for the decrease was a drop in water levels at hydroelectric dams in areas experiencing drought.

Opinion: If the Russian River goes dry, affluent Marin County has as much at stake as Mendo

PG&E has decided to withdraw the proposal that was submitted by the Inland Water and Power Commission (IWPMC), Sonoma Water, and Round Valley Indian Tribes (RVIT) to include the building of new infrastructure to continue some level of water transfer from the Eel River to the Russian River after removal of Scott and Cape Horn Dams as a part of their decommissioning plan being submitted to the Federal Energy Regulatory Commission (FERC). What does this mean for the communities dependent on the Russian River? … If the ability to divert water from the Eel River to the Russian River ceases completely, it could have severe consequences for the 650,000 people who depend on the Russian River including Marin County.

Federal energy regulators deny permits for a controversial project on the Navajo Nation

Federal energy officials denied permits for a controversial hydropower project on The Navajo Nation in northern Arizona. In its decision to deny those permits, the Federal Energy Regulatory Commission (FERC) said it was establishing a new policy about cooperation with Tribes. … The hydropower company Nature and People First was seeking permits for a “pumped storage” project in the Black Mesa area of Arizona to generate electricity for nearby cities such as Phoenix and Tucson. That kind of facility holds water from high-elevation reservoirs, then allows gravity to carry it down through turbines to generate power. Then, when electricity demand is lower, that water is pumped back up to the upper reservoir to start the process over again.

Tuesday Top of the Scroll: Atmospheric rivers boost California’s hydropower supplies

A pair of atmospheric rivers that drenched California in recent weeks will bolster the state’s hydropower systems by filling reservoirs and building up snowpack levels after a prolong drought cut supply, the state’s Department of Water Resources (DWR) data showed. As of Saturday, the state’s reservoir storage was at 118% of its historical average, according to the DWR. In Northern California, Lake Oroville, its largest reservoir, was at 78% capacity. Statewide, snowpack, which melts and fills up water reservoirs during the spring, climbed to 76% of historical average … Reservoir and snowpack and levels are good indicators of future hydroelectricity supplies, however, other water uses such as agriculture, wildlife and industrial operations are usually prioritized over electricity generation.

The river flowed rapidly from its headwaters in southern Oregon’s high deserts into Upper Klamath Lake, collected snowmelt along a narrow gorge through the Cascades, then raced downhill to the California coast in a misty, redwood-lined finish.

Upper Colorado River States Add Muscle as Decisions Loom on the Shrinking River’s Future
WESTERN WATER NOTEBOOK: Upper Basin States Seek Added Leverage to Protect Their River Shares Amid Difficult Talks with California and the Lower Basin

The White River winds and meanders through a valley.The states of the Lower Colorado River Basin have traditionally played an oversized role in tapping the lifeline that supplies 40 million people in the West. California, Nevada and Arizona were quicker to build major canals and dams and negotiated a landmark deal that requires the Upper Basin to send predictable flows through the Grand Canyon, even during dry years.

But with the federal government threatening unprecedented water cuts amid decades of drought and declining reservoirs, the Upper Basin states of Wyoming, Utah, Colorado and New Mexico are muscling up to protect their shares of an overallocated river whose average flows in the Upper Basin have already dropped 20 percent over the last century.

They have formed new agencies to better monitor their interests, moved influential Colorado River veterans into top negotiating posts and improved their relationships with Native American tribes that also hold substantial claims to the river.

District Ranger Lon Henderson with Tahoe National Forest points toward an overgrown section of forest within the Blue Forest project area. The majestic beauty of the Sierra Nevada forest is awe-inspiring, but beneath the dazzling blue sky, there is a problem: A century of fire suppression and logging practices have left trees too close together. Millions of trees have died, stricken by drought and beetle infestation. Combined with a forest floor cluttered with dry brush and debris, it’s a wildfire waiting to happen.

Fires devastate the Sierra watersheds upon which millions of Californians depend — scorching the ground, unleashing a battering ram of debris and turning hillsides into gelatinous, stream-choking mudflows.

Whiskeytown Lake, a major reservoir in the foothills of the Klamath Mountains nine miles west of Redding, was built at the site of one of Shasta County’s first Gold Rush communities. Whiskeytown, originally called Whiskey Creek Diggings, was founded in 1849 and named in reference to a whiskey barrel rolling off a citizen’s pack mule; it may also refer to miners drinking a barrel per day.

All-American Canal

As one of the most productive agricultural regions in the world, the Imperial Valley receives its water from the Colorado River via the All-American Canal. Rainfall is scarce in the desert region at less than three inches per year and groundwater is of little value. 

Lake Powell and Glen Canyon Dam

Lake Powell acts as a holding tank for outflow from the Colorado River Upper Basin States: Colorado, New Mexico, Utah and Wyoming.

The water stored in Lake Powell is used for recreation, power generation and delivering water to the Lower Basin states of California, Arizona, and Nevada. 

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.”

Hydropower generation is prevalent in the West, where rapidly flowing river systems have been tapped for generations to produce electricity. Hydropower is a clean, steady and reliable energy source, but the damming of rivers has exacted a toll on the environment, affecting, among other things, the migration of fish to vestigial spawning grounds. Many of those projects are due to be relicensed by the Federal Energy Regulatory Commission.
