Lake Powell currently holding less than 1/4 of its capacity. Today’s decision to delay release water to downstream states is unprecedented

Leviticus 26:18-20 “And if in spite of this you will not listen to me, then I will discipline you again sevenfold for your sins, and I will break the pride of your power, and I will make your heavens like iron and your earth like bronze. And your strength shall be spent in vain, for your land shall not yield its increase, and the trees of the land shall not yield their fruit.

Important Takeaways:

  • Officials take emergency measures to ease drought crisis at low Lake Powell
  • Located on the Utah-Arizona border, Lake Powell is currently at an all-time low surface elevation of 3,522 feet since it was filled in the 1960s — holding less than one-fourth of its full capacity
  • The lowest point at which Glen Canyon Dam can generate hydropower is 3,490 feet, its “minimum power pool”
  • The Bureau of Reclamation said Tuesday that it will delay the planned release of water from the Colorado River reservoir of Lake Powell to downstream states (Arizona, California and Nevada) by holding back nearly 480,000 acre-feet of water. Officials are hoping that withholding the water will boost the reservoir for an additional 12 months.
  • “Today’s decision reflects the truly unprecedented challenges facing the Colorado River Basin and will provide operational certainty for the next year,”

U.S. West faces little-known effect of raging wildfires: contaminated water

By Donna Bryson

FORT COLLINS, Colo. (Reuters) – Early this spring, water bills arrived with notes urging Fort Collins Utilities customers to conserve. The Colorado customers may have thought the issue was persistent drought in the U.S. West.

But the problem was not the quantity of water available. It was the quality.

Utilities are increasingly paying attention to a little-known impact of large-scale fires: water contamination.

Huge forest fires last year denuded vast areas of Colorado’s mountains and left them covered in ash – ash that with sediment has since been washed by rains into the Cache la Poudre River. The river is one of two sources for household water in this college town of 165,000. With more and fiercer storms expected this year, officials worry about water quality worsening beyond what treatment systems can handle.

The problem could apply to watersheds across the U.S. West, which has faced ever-increasing extremes in heat, drought and wildfire amid climate change in recent years. The United States relies on water originating on forested land for about 80% of its freshwater supply, according to a government report.

“If a wildfire is not in my watershed, it will be in someone else’s watershed,” said Sean Chambers, director of water and sewer in the nearby northern Colorado town of Greeley.

So far, Chambers and other northern Colorado utilities managers have avoided clogged pipes simply by skipping the Cache la Poudre water and using other supplies. But they worry that’s not a long-term solution, and so they sent out those notes pleading with customers to voluntarily conserve: Water lawns sparingly. Don’t let the hose run on the sidewalk when washing your car.

THE COST OF WATER

Corporate headhunter Jim Croxton moved to Fort Collins so he could take in the mountain scenery while fishing.

“I really don’t care about how big the fish are,” Croxton said after buying a half dozen flies at a Fort Collins fishing and guide shop. “I just like to be out in” nature.

He had considered drought to be the West’s water concern. But the utility’s letter urging conservation struck a chord; he had read about polluting fires affecting recreational fishing, too.

“Water in the West is a central issue,” Croxton said.

Fort Collins water rates rose 2% from January. That works out to less than $1 per month for the typical home, and generates about $600,000 toward covering an estimated $45 million in potential fire-related measures, according to calculations prepared for Fort Collins City Council.

Those measures include laying mulch on burn scars to hold down soil, and funding further fire impact research. To make up the balance, officials in Fort Collins, Greeley and other communities are pooling resources and seeking state and federal help.

Katrina Jessoe is an economist at UC Davis who has advised utilities on seeking funding to decontaminate water supplies from pollutants such as fertilizers.

“You can’t get around the fact that the cost of water is getting higher,” which could be a concern for low- and middle-income earners, Jessoe said.

Water managers say they need also to explore new ways of raising funds and making capital improvements to deal with fire-related contamination, for example, removing tastes and odors left by algae fed by nutrients in the sediments washed into reservoirs. The tastes and odors don’t mean the water is unsafe, but customers don’t like it.

Water managers are “making decisions right now that will affect whether or not this is a livable place in 50 years, 100 years,” said John Matthews, who heads the Alliance for Global Water Adaptation, a nonprofit that advises on adapting water systems for climate change.

UNPRECEDENTED FIRES

The two fires that have marred the watersheds relied on by Fort Collins, Greeley, Thornton and other towns were notable not just for the devastation they caused, but for having burned at such high elevation.

“We really don’t understand these high-elevation fires very well, because they haven’t happened very often,” said Matt Ross, an ecosystem scientist at Colorado State University who is studying how last year’s fires are impacting algae blooms now.

The Cameron Peak Fire broke out in August and was the first in Colorado history to consume more than 200,000 acres, including swathes of the Arapahoe and Roosevelt national forests and Rocky Mountain National Park. The East Troublesome came close, burning 193,812 acres across the Continental Divide.

In both cases, flames tore through forests where rivers originate and where snowpack – that frozen reservoir – builds up over winter.

Given the large region burned, researchers need to understand how long it will take for vegetation to grow back, so it can keep sediment from washing into water sources, said biogeochemist Chuck Rhoades at the U.S. Forest Service.

“The implications are that people need to think a little bit more about how to manage and sustain reservoirs,” Rhoades said.
