Little Colorado River Dam Proposals

Tribal consent is needed for dam proposals on tribal lands

As sovereign nations, tribes should decide what happens on their lands

But that didn’t stop a Phoenix-based developer from applying for federal permits to dam the Little Colorado River and its tributaries on Navajo Nation land.

Now, a federal policy requires tribal consent for dam projects proposed on tribal lands. Without the Navajo Nation’s support, the developer’s three Little Colorado River dam proposals have been canceled.

Little Colorado River Dam Proposals The backstory

Back in 2019 and 2020, a Phoenix-based developer applied for preliminary permits to build three hydroelectric projects on Navajo Nation lands without getting consent from the Navajo Nation. 

These projects threatened to flood a pristine section of the Little Colorado River Gorge, muddy its distinctive turquoise-blue waters, destroy areas sacred to Native peoples, deplete precious groundwater, and threaten the habitat of the humpback chub.

This proposal was less than five miles from Grand Canyon National Park and included two dams, one across a canyon east of the Little Colorado River and another on the Little Colorado River itself.

Less than a half mile from Grand Canyon National Park, this project included two dams. It appeared that the project’s lower reservoir would leave a Hopi sacred site underwater.

Also on Navajo Nation land near the confluence of the Colorado and Little Colorado rivers, this proposal included four dams on and above Big Canyon, a tributary to the Little Colorado River.

The confluence of the Colorado and Little Colorado rivers is culturally significant to many Native peoples in the region.

These proposed dam projects, like the not-so-distant failed Escalade tramway, threatened to disrupt the spiritual and cultural practices of people who have called the Grand Canyon home since time immemorial. One of the projects (the Little Colorado River Pumped Storage Project), would have flooded a Hopi sacred site, a place where the Hopi people believe they emerged into this world.

“This whole region … is culturally important. There are various shrines located in this area that Hopi people still visit to this day.”

What’s the status of the dams?

The Federal Energy Regulatory Commission (FERC) cancelled the preliminary permits for the Salt Trail Canyon and Little Colorado River projects in December 2022 after the developer asked to surrender those permits.

In April 2024, FERC denied the proposed Big Canyon Dam, citing the Navajo Nation’s opposition.

An issue of tribal sovereignty

From mines, to tourist developments, to proposed dams, profiteers have been trying to make a buck off the canyon since the 1800s.

The company behind these proposed hydroelectric projects claimed they’d bring billions in investment to stimulate jobs and growth. But the Navajo Nation, on whose lands the projects would be built, and other tribes with cultural ties to the area, strongly opposed the dams.

A federal policy now requires tribal consent for dams on tribal lands

In February 2024, the Federal Energy Regulatory Commission (FERC) announced it will not issue preliminary permits for projects on tribal lands, “if the tribe on whose lands the project is to be located opposes the project.”
