“All the (protected) species and all the habitat are in Nebraska,” he said.
The Central Platte Valley is the target area for least terns, piping plovers and whooping cranes, while pallid sturgeon are in the Lower Platte River.
All the water options for a proposed program extension, which will focus on reducing river depletions by another 40,000 [acre-feet] or more, are in Nebraska to be as close as possible to the target habitat.
Fassett said that with a major reservoir project now off the table, new projects will include groundwater recharge, facilities to hold water for retimed releases and water leasing.
He noted Tuesday at the annual convention of the Nebraska State Irrigation and Nebraska Water Resources associations that initial water projects were completed by all three states toward meeting the program’s first-increment goal to reduce river depletions by 130,000-150,000 [acre-feet].
However, more recent projects and those being considered for the future are only in Nebraska. “There is hydrologic logic about that,” Fassett said, because projects hundreds of miles from the target habitat are not as effective.
Nebraska’s benefits include regulatory stability the program provides for the Platte Basin. Projects in Nebraska, Colorado and Wyoming that must comply with the federal Endangered Species Act can do so through the program instead of individually, he said.
Another issue for Nebraska is its own demands to enhance water in the river. Fassett said state laws for the overappropriated area of the Platte Basin west of Elm Creek require “moving the train backward” to mitigate new water uses since 2007.
HB15-1167 is up for hearing tomorrow in the House Agriculture, Livestock, & Natural Resources committee. The bill is the brainchild of J. Paul Brown representing District 59 down in southwestern Colorado. It would direct the CWCB to study the feasibility of new mainstem storage on the South Platte River downstream from Greeley. It also directs the CWCB to utilize existing studies of the possibility of pumping water from the Missouri River Basin back to Colorado. I suppose he’s talking about the USACE’s alternative to Aaron Million’s pipeline from the Green River or the Kansas Aqueduct project.
The bill calls out the Narrows Dam Project (650,000 AF) that was authorized by the US Congress but never built for a number of reasons, most of which would be faced by any new mainstem project.
Senator Sonnenberg shows up as the Senate sponsor.
Here’s what Representative Brown had to say on the subject in the Pagosa Daily Post:
My time in the legislature is challenging and exciting. I am working hard on my bills as well as keeping up on my committee bills and the bills that come to the floor. I actually have a little advantage over other legislators in that my apartment is half a block from the Capitol, so all of my time, when I am not sleeping, showering, or attending receptions, is spent reading and preparing for action on bills.
My number one issue is water storage and primarily storage in the South Platte drainage in Colorado. Why on the South Platte? Because that is the one drainage on the eastern side of Colorado that regularly has water that leaves the state that can legally be stored and used in Colorado. When I was in the legislature in 2011 and 2012 I started paying attention to the water in the South Platte Basin that was leaving the state. There were two years in particular where over 1,000,000 acre feet per year were wasted, another where 600,000 acre feet left the state, and even today there is excess water running out of the state that could be used to augment other water needs in Colorado. If we could store that water, it would help to satisfy the demand on the Front Range and relieve the need to send water from the Western Slope to the more populated Eastern side of the Continental Divide.
For the past many years I have been learning all I can about water, water law, water compacts with other states, and everything else related to water that I could possibly learn. I started at a young age when my parents were paid to measure the water at the Colorado/New Mexico state line on the La Plata River South of Hesperus, Colorado. On most early mornings before I caught the bus for school I would measure the amount of water in the river. That information was then relayed to the water authorities in both states where ditches were closed or opened depending on their priority. I have monitored Governor Hickenlooper‚s „water plan‰ and have attended as many Water Roundtable meetings as I could possibly make. I have attended the Colorado Water Congress meetings amongst the most knowledgeable water lawyers and providers in Colorado.
I still have much to learn.
Everywhere I go I have asked folks about storage on the South Platte. The more I have learned, the more it became evident that all of the information needed to make good decisions on where and how to store water was scattered in many different places. I decided that it was necessary to pull all of that information together and that the easiest way to do so is to run a bill. That bill is HB15- 1167. It will be heard in the House Agriculture, Livestock, and Natural Resources Committee upon adjournment on the 18th of February.
Here’s the release from the United States Geological Survey (Parker Norton/Marisa Lubeck):
Video footage of an interview with lead USGS scientist Parker Norton is available online.
Streamflow in the eastern portions of the Missouri River watershed has increased over the past 52 years, whereas other parts have seen downward trends.
U.S. Geological Survey scientists recently studied data from 227 streamgages in the Missouri River watershed that had continuous records for 1960 through 2011. The scientists found that almost half of the streamgages showed either an upward or downward trend in mean annual flow since 1960, while the rest showed no trend.
The study is relevant on a large scale because the Missouri River is the longest river in the United States, with a watershed that includes mountainous to prairie topography in all or parts of 10 states and small parts of Alberta and Saskatchewan in Canada.
“The Missouri River and its tributaries are valuable for agriculture, energy, recreation and municipal water supplies,” said USGS hydrologist Parker Norton. “Understanding streamflow throughout the watershed can help guide management of these critical water resources.”
According to the study, streamflow has increased in the eastern part of the watershed, including eastern North Dakota, eastern South Dakota, western Iowa and eastern Nebraska. Annual flows have decreased in the western headwaters area of the Missouri River in Montana and Wyoming, and in the southern part of the basin associated with the Kansas River watershed.
Climate changes that affect how and where moisture is delivered to the continent may be causing some of these trends in the Missouri River Basin. Although the USGS scientists did not conduct a complete analysis of the causes, they noted that increased streamflow over broad regions occurred despite the increasing use of water. Decreased streamflow in some areas could also be related to climate change factors, or to groundwater pumping.
The scope of this mounting crisis is difficult to overstate: The High Plains of Texas are swiftly running out of groundwater supplied by one of the world’s largest aquifers – the Ogallala. A study by Texas Tech University has predicted that if groundwater production goes unabated, vast portions of several counties in the southern High Plains will soon have little water left in the aquifer to be of any practical value.
The Ogallala Aquifer spreads across eight states, from Texas to South Dakota, covering 111.8 million acres and 175,000 square miles. It’s the fountain of life not only for much of the Texas Panhandle, but also for the entire American Breadbasket of the Great Plains, a highly-sophisticated, amazingly-productive agricultural region that literally helps feed the world.
This catastrophic depletion is primarily manmade. By the early eighties, automated center-pivot irrigation devices were in wide use – those familiar spidery-armed wings processing in a circle atop wheeled tripods. This super-sized sprinkler system allowed farmers to water crops more regularly and effectively, which both significantly increased crop yields and precipitously drained the Ogallala.
Compounding the drawdown has been the nature of the Ogallala itself. Created 10 million years ago, this buried fossil water is–in many places—not recharged by precipitation or surface water. When it’s gone, it’s gone for centuries…
“The depletion of the Ogallala is an internationally important crisis,” says Burke Griggs, Ph.D., consulting professor at the Bill Lane Center for the American West at Stanford University. “How individual states manage the depletion of that aquifer will obviously have international consequences.”[…]
“We’re headed for a brick wall at 100 miles per hour,” says James Mahan, Bruce Spinhirne’s father-in-law and a plant physiologist at the USDA’s Agricultural Research Service lab in Lubbock. “And, really, the effects of climate change are branches hitting the windshield along the way.”
Last August, in a still-echoing blockbuster study, Dave Steward, Ph.D., and his colleagues at Kansas State University, informed the $15 billion Kansas agricultural economy that it was on a fast track to oblivion. The reason: The precipitous, calamitous withdrawal rates of the Ogallala Aquifer.
The Ogallala is little known outside this part of the world, but it’s the primary source of irrigation not just for all of western Kansas, but the entire Great Plains. This gigantic, soaked subterranean sponge – fossil water created 10 million years ago – touches eight states, stretching from Texas all the way up to South Dakota, across 111.8 million acres and 175,000 square miles.
The Ogallala supports a highly-sophisticated and amazingly-productive agricultural region critical to the world’s food supply. With the global population increasing, and as other vital aquifers suffer equally dramatic declines, scientists acknowledge that if the farmers here cannot meet ever-growing food demands, billions could starve.
Steward’s study predicted that nearly 70 percent of the portion of the Ogallala beneath western Kansas will be gone in 50 years. He’s not the kind of person to shout these results; he speaks slowly and carefully. Yet, he has the evident intensity of one who’s serving a greater purpose. “We need to make sure our grandkids and our great grandkids have the capacity to feed themselves,” he says.
Now the chief executive of the state, himself from a farming family, is using Steward’s report as a call to action.
“One of the things we [have] to get over … is this tragedy of the commons problem with the Ogallala,” says Governor Sam Brownback, a Republican who at age 29 was the youngest agriculture secretary in state history. “It’s a big common body of water. It’s why the oceans get overfished … You have a common good and then nobody is responsible for it.”
“That’s one of the key policy issues that you have to get around,” Brownback says in his roomy, towering office at the capitol in Topeka. “Everyone has to take care of this water.”
In that spirit, a tiny legion of farmers and landowners in the northwest corner of Kansas, where the Rockies begin their rise, have just begun year two of what could be one of the most influential social experiments of this century.
The group is only 125 in number but controls 63,000 acres of prime farmland in Sheridan County. Collectively, voluntarily, they have enacted a new, stringent five-year water conservation target, backed by the force of law and significant punishments.
The Local Enhanced Management Act, or LEMA, is the first measure of its kind in the United States. Specifically, the farmers are limiting themselves to a total of 55 inches of irrigated water over five years – an average of 11 inches per year…
“So now we have the high morality of the need to protect the ecosphere. But it’s legal to rip the tops off mountains. It’s legal to drill in the Arctic. It’s legal to drill in the Gulf. It’s legal to build pipelines. It’s legal to send carbon into the dumping ground called an atmosphere. So we’ve not yet reconciled the high moral with the legal.” [Wes Jackson]
Here’s the release from the United States Geological Survey:
A recent study conducted by scientists from the U.S. Geological Survey and published in the Journal of Geophysical Research – Biogeosciences found that a combination of climate and human activities (diversion and reservoirs) controls the movement of carbon in two large western river basins, the Colorado and the Missouri Rivers.
Rivers move large amounts of carbon downstream to the oceans. Developing a better understanding of the factors that control the transport of carbon in rivers is an important component of global carbon cycling research.
The study is a product of the USGS John Wesley Powell Center for Analysis and Synthesis and the USGS Land Carbon program.
Different downstream patterns were found between the two river systems. The amount of carbon steadily increased down the Missouri River from headwaters to its confluence with the Mississippi River, but decreased in the lower Colorado River. The differences were attributed to less precipitation, greater evaporation, and the diversion of water for human activities on the Colorado River.
For upstream/headwater sites on both rivers, carbon fluxes varied along with seasonal precipitation and temperature changes. There was also greater variability in the amount of carbon at upstream sites, likely because of seasonal inputs of organic material to the rivers. Reservoirs disrupted the connection between the watershed and the river, causing carbon amounts downstream of dams to be less variable in time and less responsive to seasonal temperature and precipitation changes.
The study presents estimates of changes in the amount of carbon moving down the Colorado and Missouri Rivers and provides new insights into aquatic carbon cycling in arid and semi-arid regions of the central and western U.S, where freshwater carbon cycling studies have been less common. This work is part of an ongoing effort to directly address the importance of freshwater ecosystems in the context of the broader carbon cycle. In the future, changing hydrology and warming temperatures will increase the importance of reservoirs in carbon cycling, and may lead to an increase in Greenhouse Gas Emissions that contribute to global warming, but may also increase the amount of carbon buried in sediments.
From the World Resources Institute (Andrew Maddocks/Paul Reig):
The world’s 100 most-populated river basins are indispensable resources for billions of people, companies, farms, and ecosystems. But many of these river basins are also increasingly at risk. As water demand from irrigated agriculture, industrialization, and domestic users explodes, major rivers on several continents are becoming so depleted that they sometimes fail to reach their ocean destinations. Add climate change, nutrient and chemical pollution, and physical alterations like dams and other infrastructure development to the mix and it’s clear that many communities rely on water resources that face an increasingly risky future.
WRI’s Aqueduct project recently evaluated, mapped, and scored stresses on water supplies in the 100 river basins with the highest populations, 100 largest river basins, and 180 nations. We found that 18 river basins— flowing through countries with a collective $US 27 trillion in GDP —face “extremely high” levels of baseline water stress. This means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity…
Decision-makers in many of world’s water-stressed basins have attempted to put management plans in place—with mixed results. The United States’ Colorado River is a prime example of a plan that, while well-intentioned, may ultimately be unsustainable. Starting in Colorado and running 1,400 miles to the Gulf of California, the Colorado River is the 14th most stressed among the world’s most populated river basins, and the sixth most stressed if ranked by size. More than 30 million people depend on it for water. The seven states receiving its water comprised 19 percent of the United States’ total GDP in 2010.
Because of its naturally arid setting—and due to its large and growing number of users and resulting high level of baseline water stress—the Colorado has become one of the most physically and legally managed rivers in the world. It is also under serious duress, exacerbated by a decades-long drought. This imbalance between supply and demand means that the river often runs dry before it reaches the Pacific Ocean—posing significant problems for wildlife, ecosystems, and communities that depend on it.
The Colorado River is an example of a basin where natural water stress is already severe. The complex web of infrastructure and governance structures around the river was, in a sense, created to ensure predictable, steady water supplies in a stressed region. On the other hand, that same development has driven increasing demands for limited supplies. Aqueduct’s country and river basin rankings deliberately do not include the effects of such extensive management, instead focusing on objective measures of underlying hydrological conditions. But the overall picture is clear: Even the most-established, iron-clad management systems start to crumble under increasing scarcity and stress…
What Is Water Stress?
Water stress is the ratio of total water withdrawals to available renewable supply in an area. In high-stress areas, 40 percent or more of the available supply is withdrawn every year. In extremely high-stress areas, that number goes up to 80 percent or higher. A higher percentage means more water users are competing for limited supplies. See the high and extremely high-stress areas highlighted in red and dark red on the maps.
