2015agwatersummit

From the High Plains/Midwest Ag Journal:

Water experts from across the state are set to convene for the 2015 Colorado Ag Water Summit, taking place Dec. 15 from 7:30 a.m. to 7:30 p.m., at the First National Bank Building at The Ranch in Loveland (5280 Arena Circle).

The event is hosted by the Colorado Agricultural Water Alliance—a group of leaders from the state’s ag industry, whose goal is to empower agriculture stakeholders to make the most informed and viable decisions regarding Colorado’s water.

The event is open to the public. Anyone interested in attending can learn more and register at http://coagwater.colostate.edu, or at http://www.coloradocorn.com.

This year’s summit is titled, “We have the Colorado Water Plan … Now what is the future of Colorado agriculture?” During the day, topics will include the Colorado Water Plan, the loss of ag water due to growing demands elsewhere, the future of food production in the state, lessons learned from the California drought, Colorado’s “use it or lose it” water laws, and the future of water regulation in the state, among other topics.

The approximately two dozen water experts and state officials slated to speak at the summit include:

Colorado Gov. John Hickenlooper;

Gregory J. Hobbs Jr., former Colorado Supreme Court justice;

John Stulp, special adviser on water to Colorado Gov. Hickenlooper;

Dick Wolfe, state engineer and director of the Colorado Division of Water Resources;

Ajay Menon, dean of the College of Agricultural Sciences at Colorado State University;

Amy Beatie, Colorado Water Trust executive director;

A.G. Kawamura, former secretary of the California Department of Food and Agriculture;
Charlie Bartlett, Colorado Agricultural Water Alliance president, Colorado Corn Growers Association vice president and Colorado Corn Administrative Committee board member; and

Several others.

“Colorado’s water challenges no doubt demand our utmost attention and a united focus,” said CAWA President Charlie Bartlett, who farms near Merino, Colorado.

In 2010, the Statewide Water Supply Initiative study showed that Colorado would need between 600,000 and 1 million acre-feet per year of additional water by 2050 to meet its municipal and industrial needs. That same study showed that water being diverted from farms and ranches to meet Colorado’s projected municipal and industrial shortfalls could result in as many as 500,000 to 700,000 acres of irrigated farmground drying up by 2050.

“Agriculture in Colorado faces big challenges when it comes to water,” Bartlett continued. “The discussions at this year’s summit will be aimed at finding the right balance in meeting Colorado’s diverse water needs, and also examining how we can do that while honoring Colorado’s water law and protecting our state’s $40 billion-plus agriculture industry—a top two or three contributor to Colorado’s economy each year. The task at hand is a difficult one, and progress can’t be made without having conversations like the ones we’ll have at this year’s water summit.”

#ColoradoRiver: Where the river ran dry: A little water restores sliver of nature in Mexican delta — Arizona Central

Here’s a report about the conservation efforts in the Colorado River delta country from Brandon Loomis writing fo the Arizona Central. Click through for the whole article and the great photos. Here’s an excerpt:

The work of maintaining a little nature along a thoroughly re-plumbed Colorado River is, in fact, never-ending.

Little more than a year ago these cottonwoods, willows and cattails were absent. Non-profit groups from both sides of the border have worked or paid to plow, plant and irrigate some 650 acres so far, essentially farming nature where it once grew wild.

They’re using canals to put some of the river back into its channel in strategic places.

Both countries are working to reverse some of the ecological damage, even as the growing population causes officials to seek new water supplies through reuse and saltwater desalination before the Southwest’s thirst leaves even less of a river for nature.

These woodland strands — tiny replicas of the river’s creation — are emblematic of the realities facing a 246,000-square-mile watershed, upstream to its mountain origins in Wyoming and Colorado. Anything that requires more water from a climate-stressed source won’t come easily….

An earthquake creates an opening for change

Riverside restoration — both along a dry channel south of the border and a wet one north of it — is an ambitious undertaking given how little the river has left to give. Without intensified water conservation or supply augmentation, the U.S. government predicts the Southwest will be short 3.2 million acre-feet by 2060. That gap is larger than Arizona’s share of the river.

Beyond aesthetics, this restoration is a start on securing the futures of about two dozen creatures whose existence the dams and canals built throughout the Colorado River Basin threw into jeopardy.

Negotiations between the nations and states that use the river allowed Mexico to store water in Lake Mead for ecological flows after a 2010 earthquake destroyed canals supplying Mexican farms.

The U.S. released about 105,000 acre-feet over several weeks last year. That’s more than enough to supply Tucson for a year, but less than 2 percent of annual supplies out of Lake Mead. On a small scale, it mimicked the sort of springtime floods that poured across the delta before Hoover Dam’s construction in the 1930s.

U.S. interests including the Central Arizona Project will recover some of the water long-term because the deal trades American-funded canal repairs for Mexican water left in Lake Mead.

The flood soaked the roots of newly planted cottonwoods, which in this climate can grow 10 feet or more in a year. Some of the new trees sank roots deep enough to tap groundwater; others will need continuing irrigation.

When the river dried up again, conservation groups who bought both permanent water rights and short-term leases from Mexican farmers began moving water through Mexico’s canals to periodically wet their restoration sites. The international agreement allows them to use up to 50,000 acre-feet — each acre-foot equaling 325,851 gallons — over five years, ending in 2017.

New negotiations next year are expected to produce an agreement for what happens after 2017.

The 2014 flood, officially labeled a “pulse flow,” was effectively an experiment to see how much water the delta needs to rebuild some biologically meaningful patches of bird and fish habitat.

It turned out that such a big flood of water all at once may not be the most effective restoration tool.

Upper #ColoradoRiver Endangered Fish Recovery Program update

From KUNC (Laura Palmisano):

It all started in 1988 when the federal government signed an agreement with Colorado, Utah and Wyoming, establishing what’s called the Upper Colorado River Endangered Fish Recovery Program.

Endangered fish at various stages of development can be found at the Colorado River Fishery Project, a national fish hatchery in Grand Junction, Colorado. Right now, the hatchery is home to two species, the endangered razorback sucker and the bonytail.

“Back when I first started, pikeminnow were probably doing better,” said Dale Ryden, a biologist with the U.S. Fish and Wildlife Service. “There were more big fish throughout the [Colorado River] basin. I had worked here for four years before I ever saw a razorback sucker out of the wild. They just weren’t around anymore. Same thing with bonytail. Bonytail were extremely, extremely rare.”

The recovery program includes federal and state agencies, environmentalists, hydropower associations and water user groups. Unlike some efforts to conserve other species, it hasn’t involved litigation.

“Working toward the same goal of recovering the fish, while allowing water development to continue… those two at first blush don’t seem to go together,” Ryden said. “But they actually work together very well.”

Just to the south of town on the Gunnison River, a tributary of the Colorado, sits a diversion dam built in the early 1900s. It blocked fish from traveling upstream for nearly 100 years, until Ryden said, they put a fish ladder on the dam.

“It goes up and around the Redlands Dam and provides upstream fish passage for native and endangered fish.”

The ladder is a selective passage. Biologists use it to trap fish traveling upstream. Then they hand-sort them so only native fish can continue up the Gunnison River. Two similar ladders have been installed along the Colorado and another is in the works on the Green River in Utah.

The ladders might help fish get to their upstream habitats, but water levels also matter.

Brent Uilenburg with the Bureau of Reclamation said there is some recognition that “the dams and canals we operate that take water out of the Colorado River Basin have contributed to the decline of the species.”[…]

The bureau is also the largest single source of funding for the conservation program. States, water developers, and hydropower associations also contribute, totaling more than $350 million over the past 25 years.

That funding helped the Grand Valley Water Users Association in Grand Junction optimize its system. Before, said Kevin Conrad, the association’s operations manager, they diverted more water than necessary.

“Whatever they weren’t using, it went out through spillways on the canal back to the river, but it was below a point where the fish couldn’t benefit from it.”

Conrad said the upgrades also help conserve water and keep it in place for the fish.

The ultimate goal of the recovery program is to remove the fish from the endangered species list. Biologist Dale Ryden said habitat restoration, water flow improvements, hatchery programs, and invasive fish removal are helping the fish rebound.

“Probably the biggest star in terms of recovery prospects is the razorback sucker,” said Ryden. “Bonytail are really doing much better with the really robust stocking program.”

Humpback chub seem stable, but Ryden said questions remain about the Colorado pikeminnow.

USGS national water census: #ColoradoRiver Basin geographic focus area study

Click here to read the fact sheet from the United States Geological Survey. Here’s the introduction:

The U.S. Geological Survey’s (USGS) concept of a national census (or accounting) of water resources has evolved over the last several decades as the Nation has experienced increasing concern over water availability for multiple competing uses. The implementation of a USGS National Water Census was described in the USGS 2007 science strategy document that identified the highest priority science topics for the decade 2007–17. In 2009, the SECURE Water Act (Public Law 111–11, subtitle F) authorized the USGS to create a Water Availability and Use Assess­ment Program for the Nation, and in 2012, the Department of the Interior WaterSMART initiative provided funding to begin implementation of the USGS National Water Census (NWC).

Generally, the USGS NWC approaches water-availability assessment in terms of a “water budget.” The water-budget approach seeks to better quantify the inflows and outflows of water, as well as the change in storage volume, both nationally and at a regional scale and, by doing so, provides critical information to managers and stakeholders responsible for making water-availability decisions. The NWC has two primary components: Topical Studies and Geographic Focus Area Studies. Topical Studies do research on methods that can provide nationwide estimates of particular water-budget components at the subwatershed scale. Some examples of NWC Topical Studies include estimation of streamflow at ungaged locations; periodic quantification of evapotranspiration; and water use related to development of unconventional oil and gas. These efforts are planned to include additional topics in the future. Geographic Focus Area Studies (FASs) assess water availability and use within a defined geographic area, typically a surface-water drainage basin, to increase the understanding of factors affecting water availability in the region. In the FASs, local stakeholder input helps the USGS identify what components of the water budget are in most need of additional understanding or quantification. Focus Area Studies are planned as 3-year efforts and, typically, three FASs are ongoing in different parts of the country at any given time.

The Colorado River Basin (CRB) and the Delaware and Apalachicola-Chattahoochee-Flint (ACF) River Basins were selected by the Department of the Interior for the first round of FASs because of the perceived water shortages in the basins and potential conflicts over water supply and allocations. After gathering input from numerous stakeholders in the CRB, the USGS determined that surface­-water resources in the basin were already being closely monitored and that the most important scientific contribution could be made by helping to improve estimates of four water­-budget components: evapotranspiration losses, snowpack hydrodynamics, water­-use information, and the relative importance of groundwater discharge in supporting streamflow across the basin. The purpose of this fact sheet is to provide a brief summary of the CRB FAS results as the study nears completion. Although some project results are still in the later stages of review and publication, this fact sheet provides an overall description of the work completed and cites the publications in which additional information can be found.

Acequia activism: Men and women help protect a vital network — The Albuquerque Journal

From The Albuquerque Journal (T.S. Last):

Water rights and urban development are the two biggest impediments to the acequia system that has been a part of New Mexico’s unique history since shortly after the Spanish arrived in the American Southwest more than 400 years ago.

It is said that acequias, which refer both to the irrigation infrastructure itself and the organizational structure of the water-sharing network, formed one of the first democracies on the continent. Then, as they do now, the parciantes, or acequia members, elect the mayordomo, who is in charge of managing the acequia.

To be sure, Native Americans used a channel system to irrigate crops prior to the arrival of the Spanish in New Mexico. But it was the Europeans, who learned from the Moors of North Africa – “acequia” actually an Arabic word meaning “canal” – who developed expansive irrigation systems and a system of governance that has stood the test of time.

“The fact that they are still flowing, and are governed through ancient customs and modern law, through the Spanish-colonial period, and territorial period, to statehood, speaks to their resiliency,” said Paula Garcia, executive director of the New Mexico Acequia Association, a nonprofit organization that, according to its mission statement, works to protect water and acequias, grow healthy food for families and communities, and honor the cultural heritage.

Part of that cultural heritage involves the annual spring cleaning of the acequias. That’s when the parciantes are mobilized to clear the ditches of debris, make any repairs to “compuertas,” or turnouts, and get the irrigation system ready for the growing season.

“That’s an event of great cultural importance and it serves a practical need because there’s always a need to have people clean ditches,” Garcia said, adding that family members who have moved away often come home to pitch in. “It’s a part of someone’s identity to come home and help clean the ditches in March and April.”

It’s not just Hispanic families anymore. She said that members of other ethnic groups who have purchased property tied to acequias typically embrace the system.

“Today, it’s more multi-cultural,” she said.

Garcia said there are approximately 700 acequias currently operating in New Mexico, a good many more in southern Colorado and only a few left in Texas…

El agua es vida

The motto of the state acequia association is “el agua es vida,” water is life. It is what sustains us and, without it, we would not survive.

Each year, the acequia association holds a Congreso, its annual convention, at which there are workshops, seminars and an awards ceremony.
