Colorado River

Seven states will negotiate access to what’s left in the river. My job is to represent all of Colorado’s interests

The humpback chub was first listed as endangered in 1967

La Niña winter could mean dry winter for southern Colorado, but conditions better than this time last year.

If a summer of high temperatures and low Colorado River flows is not the right time to stop fossil-fuel development on public lands, when is the right time?

With a crew that included a tribal leader, Utah state politicians, scientists, water-guardians, ranchers and environmentalists, the two senators donned river sandals and PFDs and joined their wives for a float on the Colorado River

The Bureau of Reclamation recently declared the first-ever shortage on the Colorado River, which means Arizona, Nevada and Mexico will get less water than normal next year

Choking on ozone spikes, losing favorite hiking spots like Hanging Lake, sweating through fall school days — climate change is now.

At least 54% of the state now is experiencing drought conditions, compared to 100% this time last year. But record-breaking heat and a dry winter could mean conditions worsen, a climatologist says.

As of Sept. 1, the reservoir was 37% full, which is about 68 feet down from a full reservoir, and a ring of muddy shoreline was growing

The multimillion-dollar effort led by Lawrence Berkeley National Laboratory launches next week.

Colorado River Basin states have a problem even before considering climate change: There are more water rights on paper than there is water in the river.

First-ever shortage declaration on key western river means big losses for Arizona and Nevada. Colorado’s own time for cuts and living with less is coming soon, experts warn.

Wildlife crews and water quality experts struggle to even assess the damage, as emergency management officials warn of threats to the western lifeline for years to come.

Lake Powell is the second-largest reservoir in the United States, right behind Nevada’s Lake Mead, which also stores water from the Colorado River. Both are shrinking faster than expected.

Climate change, drought and high demand are expected to force the first-ever mandatory cuts to a water supply that 40 million people across the American West depend on

Conservation groups want more “cash for grass” and other plans to acquire new water by saving it. But Denver and Aurora, among others, say there’s only so much to cut before a new dam is needed.

Gov. Jared Polis is preparing state and federal disaster declarations as state officials assess “extreme damage” to the highway and threats to the rail line that runs adjacent to the Colorado River

The highway likely will be closed through the weekend because of the massive level of clean up required and heavy rain in the weather forecast.

Wildfire smoke has help deflect solar radiation and kept the river relatively cool. But aquatic biologists warn hot weather, low water levels and sediment in the river could combine to starve trout of oxygen and future bans.
