Not all manmade dams are the correct “green” path forward, as witnessed after the removal of one restored riverine life.
An extremely long legal battle has come to an end, transforming the environment much quicker than most expected.
Sometimes, the world can only become a better place if mankind learns to “listen to nature” and its historic systems.
But will the revival of a river inspire other local communities to take a stand against hydropower?
How the energy of water has risen in dominance
One of the greatest feats of engineering worldwide is perhaps that of manmade dams.
Historically, they were constructed to assist with water supply for irrigation and agricultural development in arid regions.
Eventually, the infrastructure took on another role by assisting in flood control and creating deep channels for shipping.
However, it soon became one of the most popular renewable energy sources worldwide.
Known as hydropower, the ability to generate reliable, “baseload” power became the root of its dominance.
This approach to reshaping rivers to build dams was seen as the ultimate path to global clean energy resilience.
But as climate change continued to impact the planet, the consequences of manmade hydro-utilities soon came to light.
This is why intervention is key, before the complete collapse of the surrounding ecosystems follows.
Unfortunately, history has shown that the battle is not easy, nor short.
From building dams to changing the course of nature
The current climate crisis has effectively made traditional dam infrastructure non-ideal.
Rising global temperatures are transforming these reservoirs into ecological and economic liabilities.
NOAA has sounded the alarm about atmospheric patterns breaking, which could accelerate the depletion of water supplies.
Droughts threaten to disrupt the steady force needed to keep hydroturbines spinning to continue meeting energy demands.
Furthermore, glaciers and snowy mountaintops are melting faster than expected, which means natural “water towers” are fading. This increases concerns about a global chain reaction.
Beyond the risk of a worsening freshwater crisis worldwide, existing dam infrastructure is facing the altered natural chemistry of rivers.
Usually, the natural flow would cool basins. Now, stagnant reservoir water is being transformed into “hot zones” by a “hotter” sun.
This causes thermal pollution, effectively making “green” energy projects less sustainable.
For this reason, local tribes, whose environment and livelihood were disrupted, decided to step up.
The long battle to restore the flow of riverine life
Hydropower is fundamental in the U.S., ensuring grid reliability, a diverse renewable energy portfolio, and water management.
Despite its key role, the Yurok, Karuk, and Klamath Tribes led a 50-year struggle to undam the Klamath River.
For them, it became a fight for survival.
The hydroelectric dams disrupted their connection to salmon vital for food and cultural sustenance. Water quality deteriorated, and surrounding ecosystems were failing.
Winning the battle to bring the river “back to life”
The utility owner had to choose between spending over $300 million on upgrades and fish ladders or dismantling the dams.
The latter option was the most sustainable (and cost-effective) way forward.
The last barriers fell in 2024. Within months, the Coho salmon returned to the upper basin for the first time in 60 years. Other species also returned.
Thousands of acres of stagnant “hot zones” were replaced by vibrant wetlands. The receding water also revealed sacred sites like the K’íkac’éki Canyon.
The successful restoration of the Klamath River and surrounding ecosystems highlights why clean energy expansion must not compromise the environment.
Rivers must be managed as living systems to prevent the destruction of historic cultures and species that depend on them.
Progress is only sustainable when it is conducted responsibly. By protecting natural water cycles, sustainability could align with Earth’s natural systems.
