23rd Annual Eagle River Cleanup
About 300 people participated in this year’s Eagle River Cleanup, which was the 23rd annual. A large youth turnout at this year’s event helped forward one of the goals of the watershed council — to leave a conservation legacy for generations to come.
“It’s a start of environmentalism,” watershed council executive director Holly Loff said Saturday. “It connects the community; everyone has worked hard to do something that does make a difference.”
Loff said they expect to see about 4,000 pounds of trash collected from local waterways as a result of Saturday’s efforts.
While the trash itself isn’t often as detrimental to the river as the pollution you can’t see, a clean riverbank says a lot about a community, said Eagle County Commissioner Jeanne McQueeney.
“It takes away from the experience when you see trash as you’re rafting past, or when you’re trying to fish,” McQueeney said.
Because of technology, [Dwane] Roth is working to embrace what might seem like an unfathomable concept in these parts – especially when you can’t see what is happening underground.
Sometimes the crop isn’t thirsty.
“It’s difficult to shut off,” Roth said. “But I called my soil moisture probe guy. He said the whole profile was full and it was only the top 2 inches that was actually dry. So there was no need to turn that irrigation engine on and pump from the Ogallala.”
Now he is hoping to change the mindset of his peers across a landscape where corn is king and the Ogallala Aquifer – the ocean underneath the High Plains – has been keeping the decades-old farm economy going on the semi-arid Plains.
At least it is for now.
Underlying eight states across the Great Plains, the Ogallala provides water to about one-fifth of the wheat, corn, cotton and cattle production in the United States. It’s also a primary drinking water supply for residents throughout the High Plains.
But the aquifer that gives life to these fields is declining. It took 6,000 years to fill the Ogallala Aquifer from glacier melt. It has taken just 70 years of irrigation to put the western Kansas landscape into a water crisis.
An economy centered on water is drying up.
With his own water levels declining, Roth wants to make sure there is water for the next generation, including his nephews who recently returned to the farm.
On this hot, summer day, water seeped out of a high-tech irrigation system he is testing on his Finney County farm. Soil probes are scattered about, telling him what is happening below the surface.
Roth also has pledged to the state to cut back his usage by 15 percent through changing farming practices and implementing new technology.
He wants to make a difference, but, he stressed, he can’t slow the decline alone.
For the past two years, Roth’s fields have been part of a closely watched demonstration project aimed at showing farmers how to use less irrigation water on their crops. Now he he is taking it a step further.
With some areas in northern Finney County declining by more than 70 feet since 2005, Roth is helping spearhead a regional effort to curtail pumping through a Local Enhanced Management Area. LEMAs were implemented five years ago as a tool to extend the life of the state’s water resources.
He’s not the only one looking toward the future. A small but growing group of irrigators are considering different tools to cutback water use. Some are implementing technology. Some are looking at LEMAs. Others are forming their own, farm-wide plans for mandatory cutbacks.
“It’s for the kids you don’t see yet,” Roth said of why he’s doing this. “It’s for the generation that’s not here.”
The High Desert Conservation District has teamed up with farmer Brian Wilson and Teeter Irrigation, of Johnson City, Kansas, to determine if the company’s trademarked Dragon-Line system will work for this area.
Instead of using the nozzles on the center pivot to irrigate, a row of drip lines are attached that drag behind the sprinkler watering the crop at its base instead of from above.
“It saves water and reduces evaporation, erosion and runoff,” said Travis Custer, agricultural consultant with High Desert. “It is the first trial of the technology in the area.”
To compare crop yields, one section of the center pivot irrigates a field of wheat normally from spray nozzles, and an adjacent section utilizes a series of drip lines attached to the nozzles. After harvest, the yields will be compared. Soil moisture monitors have also been installed in areas watered by the drip and nozzle sections of the sprinkler.
The hybrid center pivot and drip line technology was created by Teeter Irrigation, and launched in 2015. The technology has proven effective in Kansas and other plain states that irrigate from an underground aquifer, Custer said.
But since local farms use surface water delivered via ditches and pipelines that carry more debris, a filter system had to be installed on the center pivot being used on the Pleasant View trial…
Farmers have switched to center-pivot sprinkler technology because it is less labor-intensive than side-roll sprinklers, which must be moved by hand. Center pivots are automated, and move in a circular pattern, watering from a row of nozzle heads. Water flow and speed are adjustable and can be controlled remotely.
But center pivots work best on flatter ground. On undulating farmland and fields with steeper slopes, center pivots can cause water to pool in low spots and run off the field or drain into the sprinkler’s wheel tracks, creating muddy conditions.
What’s exciting is that the drip-system attachment to the center-pivot could eliminate those problems because the water is delivered at ground level, said Steve Miles, board member of the High Desert Conservation District…
It appears to be working in the test plots. The lower areas of the drip-line section are not getting waterlogged, and there is less runoff the field. How often the filter-system has to be flushed is also part of the experiment.
As metro Denver grows, what’s the outlook for its water supply? We went to the source to ask.
Denver Water is the state’s biggest water utility, ensuring that 1.4 million customers in Denver and many surrounding suburbs have enough clean water for drinking, showering, cooking and yard watering.
Jim Lochhead was appointed its CEO and manager in 2010, after working for decades as a lawyer negotiating water rights and uses across the nation.
He sat down with me to talk about Denver’s water future. Here are some highlights.
What challenges lie ahead?
We’re doing an integrated resource plan, a 50-year look ahead to the challenges we face and how we face them — but it’s scenario planning, rather than math. Before, we looked at the past and how much water was available, figured how many people there would be in the future and did the math. But saying “we just need to get more water” doesn’t work anymore. The future will not look like the past for a number of reasons.
On the supply side, there may be more extended droughts, greater severity of weather events, and a warming climate. For demand, we’ve seen demand dropping due to our campaign for water conservation, but it’s also through more efficient fixtures and more density in the city — which means more efficiency.
Economics plans a part to, we could have economic downturns or just chug along, or the millennials moving into the downtown apartments might move to the suburbs. We’re creating different scenarios for all that.
A snowy winter in the Rocky Mountains helped Colorado River water users escape a shortage for the next year and likely for at least two more, federal water managers project, though a hot spring made the escape a narrow one.
The river’s reservoirs combined have gained 5 percent of their capacity in the last year, and now sit at 57 percent full. It means customers using Central Arizona Project water in the Phoenix and Tucson areas won’t lose deliveries next year and have just a 31 percent chance of losing some water in 2019 — a marked improvement from roughly even odds projected in recent years.
“We had a fairly decent runoff this year, which certainly helped us trend in the right direction,” U.S. Bureau of Reclamation spokesman Doug Hendrix said Tuesday.
Conservationists say the projections provide a nice reprieve but that the seven states on the river must use the time to plan and save more water and prevent future pain.
“I don’t think we really have time to wait for an official shortage declaration,” said Jeff Odefey, drinking-water-supply program director for the group American Rivers…
A 2007 agreement between Reclamation and the seven states said CAP customers, starting with farmers, would lose some of their river water in any year when the August projections show Lake Mead’s elevation dropping below 1,075 feet elevation on Jan. 1.
The lake would already be well below that level if not for conservation measures by the states and Mexico, Arizona Department of Water Resources Director Tom Buschatzke said in a statement Tuesday…
The government currently projects Lake Mead will end this year well above shortage level, at 1,083.46 feet. It was about 1,080 feet throughout on Tuesday, and should gain elevation as fall temperatures cool and reduce the demand for irrigation water, allowing more of the inflow to pool behind the dam…
The Green River, the biggest tributary to the Colorado, had a record snowpack in Wyoming last winter, Odefey said, while western Colorado was also above normal.
Warm weather then melted, evaporated and increased demand for water, reducing earlier predictions that Lake Mead would get a bigger boost…
The states and the federal government have already propped up the reservoir by paying for conservation and efficiency improvements with a goal of leaving water behind the dam instead of earmarking it for a particular use.
From 2012 through 2016, the states collectively saved 1.2 million acre-feet of water in the reservoir, said Jennifer Pitt, the National Audubon Society’s Colorado River program director.
That’s enough water to support a few million households, and it approaches the Central Arizona Project canal’s share of the river.
“It’s a great demonstration of the fact that water conservation can be done,” she said. “It makes me optimistic about the future.”
According to projections released Tuesday by the U.S. Bureau of Reclamation, the reservoir east of Las Vegas will have enough water in it on Jan. 1 to stave off a first-ever federal shortage declaration — and the mandatory water cuts for Nevada and Arizona that would come with it.
The lake is also on track to avoid a shortage in 2019, thanks to decreased demand downstream on the Colorado River and a larger-than-usual influx of water from Lake Powell upstream.
The extra water from Lake Powell is expected to raise Lake Mead’s surface by more than five feet by the end of the year.
The new federal projections come as officials in the United States and Mexico finish work on a new binational agreement aimed at stretching limited resources on the Colorado and keeping more water in Lake Mead.
Negotiators from the two countries, including representatives of the Southern Nevada Water Authority, have agreed on a range of water-sharing and water-saving initiatives, including voluntary cuts that Mexico could begin taking as soon as next year to prop up the overdrawn, drought-stricken river system.
The agreement also spells out how much Mexico would have to reduce its river use during a declared shortage and how much extra water the nation would get in the event of a surplus on the Colorado.
The new pact, known as Minute 323 to the Mexican Water Treaty of 1944, extends many of the provisions of an earlier treaty amendment approved in 2012 and set to expire at the end of this year. For example, Mexico will be able to keep storing some of its river allotment in Lake Mead, and U.S. water agencies will be able to continue to invest in infrastructure improvements south of the border in exchange for a portion of the saved water.
The water authority board is expected to vote Thursday to sign on to Minute 323 when the agreement is finalized next month.
“It’s a good deal for both countries,” Authority General Manager John Entsminger said.
The most important thing about the deal is the certainty it provides, Entsminger said. Water managers in both countries will now know what to expect should the river continue to shrink.
“It’s a big deal because the last thing you want is uncertainty when you get into a shortage condition,” he said.
The voluntary water cuts Mexico would take under the treaty deal hinge on a separate but related pact being negotiated by water officials in Nevada, Arizona and California.
The three states have agreed in principle on the so-called Lower Basin Drought Contingency Plan, under which Nevada, Arizona and, eventually, California would voluntarily leave some of their river water in Lake Mead when the surface of the reservoir falls to certain trigger points.
Entsminger said the multistate deal is on track for completion next year despite some public spats and lingering disagreements among water agencies in Arizona and California over how the voluntary cuts should be made in each state.
“I do believe it will happen,” he said…
The Las Vegas Valley relies on Lake Mead for 90 percent of its drinking water supply. The surface of the reservoir now sits at about 1,080 feet above sea level, roughly 130 feet lower than it was before the current drought began on the Colorado River in 2000…
Above-average flows in the Colorado River helped keep Lake Mead out of shortage for another year, but the real news is on the demand side.
Over the past year, Nevada, Arizona and California combined to use less than 7 million acre-feet of river water for the first time in 25 years.
Colby Pellegrino, Colorado River programs manager for the Southern Nevada Water Authority, said the decline in demand is proof that conservation efforts on the Colorado are making an impact.
The last time the three lower basin states combined to use less than 7 million acre-feet of river water was in 1992, when the region was home to roughly 7 million fewer people than it is now.
“We’ve successfully decoupled our economic prosperity from our water use,” Pellegrino said.
Here’s the release from the US Bureau of Reclamation (Justyn Liff, Jenny Ward):
The Bureau of Reclamation has released a draft environmental assessment on Phase II of the Cattleman’s Ditches Piping Project located in Montrose County, Colorado. The project would replace approximately 6.1 miles of open irrigation ditch with 5.1 miles of buried water pipeline. The purpose of the project is to reduce salinity loading in the Colorado River Basin.
