When Will Klamath Dam Removal Take Place? A Complete Timeline for the Largest Dam Removal Project Ever.
The largest ever dam removal project in the United States will completely change the makeup of multiple Northern California communities. Behind decades of work from multiple groups, specifically local Native American tribes, the Klamath River will flow free again in the next two years.
The Klamath River dam removal project has cleared every major hurdle in the courts, paving way for the deconstruction of four dams through NorCal and southern Oregon in 2023 and 2024. With all eyes on the Klamath River, let’s take a look at the scheduled timeline for the upcoming removal of the dams.
According to the Klamath River Dam Removal Corporation, personnel will begin to arrive at Copco Dam No. 2 in early 2023. Pre-removal construction will include bridge and road improvements to the nearby area in anticipation of major equipment being transported to the area. Copco No. 2 will then be removed in the summer of 2023, the first dam scheduled to be removed due to its small size.
After the first dam’s removal, construction crews will begin reservoir drawdown and deconstruction on the remaining three dams in early 2024. This will last the entire year, with the Iron Gate Dam being the last one to go due to its size and the amount of material that must be removed. All dams are expected to be removed by the end of 2024.
Why Remove the Dams in the Middle of Drought?
The argument behind removing dams is nuanced. There are well over 1,000 dams in California, some more than a century old. Most dams were erected to establish critical water supply, but also for hydroelectric power generation and flood control. If Shasta and Keswick Dams in Shasta County were removed, towns like Redding could literally be washed away during spring flooding season.
But the Klamath Dams were built specifically for the purpose of generating electricity, a practice that has since been modernized by more efficient energy providers. The dams provide no irrigation diversions, no drinking water, and almost no flood control benefit. Managing the aging structures today costs more than they’re worth.
The dams were once operated by Warren Buffet’s company PacificCorp. For years Pacificorp refused to consider removing the dams. It was only after they looked ahead and began to contemplate what it would cost to upgrade the dams for fish passage to adhere to modern-day laws. Long story short, it didn’t pencil out. It became obvious that it would be cheaper to just remove them.
What Will Dam Removal Look Like?
The question remains of what the Klamath River will look like after dam removal. Nearby communities who count on the Klamath for their way of life are sitting in limbo as the project ramps up. There’s no telling what complications could take place during removal, but we can look at the project done by our PNW neighbors of the north to see what the removal of the dams could potentially look like.
The two hydroelectric dams on Washington’s Elwha River were removed 6 years ago to revive the fish populations in the beautiful river feeding the Pacific Ocean. The dams were no longer providing large amounts of electricity (especially compared to more modern methods) and had many negative impacts on the health of the watershed.
Sound familiar? The Elwha’s dam removal project was the first of its kind and can show us exactly what the Klamath might look like under a similar project.
While the removal of Elwha’s dams were initially concocted to allow fish passage and revive the salmon populations, the area witnessed many more positive outcomes than they bargained for. Just a couple of years after the dams were removed, sediment and wood were rushed down to the ocean after 100 years of build up. The beaches on the ocean at the mouth of the river were completely altered, illustrating the immense healing power of nature. Due to this flush of the system, the kelt and eel grass beds were restored, returning the natural habitat for the marine wildlife to the area.
The fish rushed back into the river immediately, with sightings of Chinook and Coho salmon, trout and steelhead in the river system upon removal. With the spawning fish unable to return to the original spawning grounds for 100 years, it was almost as if they were sitting there waiting for passage once again.

The spawning salmon breathed new life into the watershed, with their rotting carcasses providing nutrients and food to the system following their spawn. This brought insects, birds, elk and otters back into the area and the dirt formally sitting in the reservoirs above the dams were quickly restored for wildlife with 300,000 plants and thousands of pounds of seed.
Here is a quick glimpse of the recovery of the Elwha River:
The Science Behind Dams
Dams degrade water quality. They also block the rich nutrients brought into the habitat by spawning anadromous fish. The salmon and steelhead using our rivers for spawning have traveled and fed in thousands of miles of ocean water from as far away as Canada, Alaska or even Russia. When they die after spawning these exotic nutrients supercharge the ecosystem benefiting all forms of life. The reservoirs behind dams warm and broaden the river corridor often providing warm water habitat for destructive non-native species. Even though many dams provide fish ladders allowing passage over the dams, they are largely statistical failures. For reasons known only to the fish, many fish will not use them. This creates a large pod of fish below the dams that will never spawn. The dams also give piscivorous species (fish that eat other fish) like pikeminnows a terrific opportunity to dine on salmon and steelhead smolts that will never make it to the ocean.
Dam removal is about much more than restoring endangered fish populations. If you consider the fact that everything in an ecosystem is connected, you realize you cannot alter one aspect of a river without impacting everything else. Once streams are returned to their natural states, they are able to cleanse themselves, wash out all the sediments that smother aquatic plants, insects and fish. Improved water quality also impacts everything from associated wetlands (and the life sustained there) to coastal beaches and estuaries.
So, you think California has a dam problem? We are far from alone. According the the US Army Corps of Engineers, there are over 80,000 dams three feet or greater in this country. California is on the cutting edge of a national movement for dam removal where the benefits outweigh the costs for retrofitting century-old structures built in an age where we thought we had an endless supply of good habitat.
As the dam removal project on the Klamath River continues to move forward, many questions still remain. Come 2025, the Klamath Basin may be a completely different place. Only time will tell.
Elwha dam was removed in 2012, 11years ago
The silt killed everything in the river for several years before finding its way to the mouth
This year may be the first year to allow limited fishing after 11 years
Only 2-5 percent of returning kings are native the rest are hatchery fish that stay by the hatchery
Vary few kings go into new water above the dams, steelhead have made it upriver
The best estimates are it will take at least 20 years to have a viable population where hatcheries won’t be needed
There are people who work for Elwha tribe that would be happy to talk with you to get the facts
I know this web page provides quality dependent content
and other material, is there any other site which provides these stuff in quality?
Wow that was odd. I just wrote an really long comment but after I clicked submit my comment didn’t show up.
Grrrr… well I’m not writing all that over again. Anyhow, just wanted to say fantastic blog!
You claim that “The largest ever dam removal project in the United States will completely change the makeup of multiple Northern California communities.” Really? Completely change communities?
This is the sort of nonsensical hyperbola that our current approach to journalism produces.
Removal of four PacifiCorp dams will have important positive impacts. But it will not change the allocation of water in the Klamath River Basin and it is that allocation, which favors irrigation over the needs of stream ecosystems, which is the number one factor limiting the recovery of Klamath River Salmon and the aquatic ecosystems on which they depend.
Furthermore, removing four of PacifiCorp’s five Klamath River Dams will marginally improve but not fix the River’s water quality problems which are another major reason Klamath River salmon have not recovered. The water quality degradation is the direct result of agricultural discharges and failure of agricultural producers to protect riparian areas and this reality will not improve unless and until we require that agricultural producers protect riparian areas and water quality.
Please provide us with realistic assessments of the impact of our actions on the environment and please avoid the irrational hyperbola seen in this article.
