It was the warmest decade since the start of modern measurements in 1850, with more national temperature records broken than in any previous decade. Along with analyzing global and regional temperatures and precipitation, the report took a close look at extreme events, including heat waves in Europe (2003) and Russia (2010), Hurricane Katrina in the United States of America, Tropical Cyclone Nargis in Myanmar, droughts in the Amazon Basin, Australia and East Africa and floods in Pakistan.

The decade was the warmest for both hemispheres and for both land and ocean surface temperatures. The record warmth was accompanied by a rapid decline in Arctic sea ice, and accelerating loss of net mass from the Greenland and Antarctic ice sheets and from the world’s glaciers.

As a result of this widespread melting and the thermal expansion of sea water, global mean sea levels rose about 3 millimeters per year, about double the observed 20th century trend of 1.6 mm per year. Global sea level averaged over the decade was about 20 cm higher than that of 1880, according to the report.

Drought news: Reclamation details changes in Rio Grande flows #NMdrought #COdrought

From email from Reclamation:

As of July 2, the Middle Rio Grande Conservancy District exhausted its water stored in reservoirs on the Rio Chama. Flows in the Middle Rio Grande are now primarily comprised of federal supplemental water leased for the Rio Grande silvery minnow and water released from El Vado Dam to supplement the meager natural flows for irrigation of the six Middle Rio Grande Pueblos’ Prior and Paramount lands.

The water in the river below Cochiti Dam is either water Reclamation leased specifically to maintain flows below diversion dams for the silvery minnow or irrigation water for the Pueblos. The only water that the MRGCD can divert and deliver to its non-Pueblo farmers are native flows occurring due to rain or water remaining after the minnow and Pueblo needs are satisfied.

“We are now up to 36 months of consecutive drought. It’s the driest three-year period on record for much of New Mexico. Reclamation is focused on working closely with the Pueblos and MRGCD to ensure that the water in the river is reaching its intended destinations,” said Albuquerque Area Manager Mike Hamman. “It is critical to all water users that the small populations of silvery minnow are maintained through the summer in order for us to meet our commitments under the Endangered Species Act.”

Reclamation and other water management agencies are operating under an emergency management plan developed by the Minnow Action Team, which was formed under the Middle Rio Grande Endangered Species Collaborative Program. This plan allows for earlier than usual drying of parts of the river as well as deviation from target flows normally required under the 2003 Biological Opinion issued by the U.S. Fish and Wildlife Service. The intent is to stretch out supplemental water and deliver limited amounts to key areas that provide refugial habitat to the silvery minnow.

CPC: The latest El Niño/Southern Oscillation (ENSO) Diagnostic Discussion is hot off the presses #COdrought

Click here to read the discussion. From the synopsis:

During June 2013, below-average sea surface temperatures (SST) prevailed in the eastern Pacific, while near-average SSTs persisted across the rest of the equatorial Pacific. This ENSO-neutral pattern was also reflected in the Niño indices, which were warmer than -0.5°C in Niño-4 and Niño-3.4 and cooler than -0.5°C in Niño-3 and Niño-1+2 during the month. Meanwhile, the oceanic heat content (average temperature in the upper 300m of the ocean) anomalies increased during June, due to the emergence of above-average subsurface temperatures in the eastern half of the Pacific. Across the equatorial Pacific, the low-level winds remained near average, while weak upper-level westerly anomalies persisted in the central Pacific. Convection remained enhanced over Indonesia and weakly suppressed near the International Date Line. Collectively, these atmospheric and oceanic conditions were consistent with ENSO-neutral.

Southern Delivery System: Transmountain water not subject to just one use

From Colorado Springs Style (Joe Stone):

As SDS Program Director John Fredell explains, Colorado water law dictates that water native to Front Range streams and rivers can only be used once. For example, Colorado Springs Utilities can divert Fountain Creek water for use by residential customers, but any of that water not consumed must be treated and released for downstream users. With Western Slope water, Colorado Springs has the right to “use the water to extinction.”

However, Fredell says, no “plumbing”currently exists to allow the Springs to fully consume its Western Slope water. The water gets used once then flows downstream to the Arkansas River via Fountain Creek. By connecting a pipeline from Pueblo Reservoir to the Springs’ water system, the SDS provides the plumbing that will change that. Colorado Springs Utilities will soon be able to exchange water sent down Fountain Creek for water stored in Pueblo Reservoir. “With SDS, we’re basically reusing our water, getting two to three uses of that water, which is extremely valuable.”

Fredell points to several economic benefits of reusing the city’s Western Slope water, including preservation of Arkansas Basin agricultural water rights, which are frequently targeted by growing Front Range cities. Once municipalities acquire agricultural rights and change them to municipal use in Water Court, productive farmland is dried up with little chance of ever being returned to agricultural production.

The immediate benefits of the SDS include revenue for local businesses and jobs for the local workforce. “The SDS is the biggest thing going,” says Fredell, “and we worked hard to get local contractors and companies involved. A lot of people questioned the timing of this project, asking why we would start such a big project during an economic downturn. My answer is, ‘Why wouldn’t you start now?’ You get better pricing on materials and services because of a more competitive market, and you help move the economy forward. This project provides work for over 300 Colorado businesses.” Furthermore, historically low bond rates add up to huge savings over the project’s forty-year finance period.

Officials with Colorado Springs Utilities must also take into account the age of the city’s existing water infrastructure. Bringing Western Slope water to the Springs requires a complex system of twenty-five dams, 200 miles of pipes and four major pump stations in nine counties. That infrastructure is aging, and some parts of the system are more than fifty years old. As parts wear out and fail, the redundancy provided by the SDS will ensure an uninterrupted water supply during repairs and maintenance, which will become more frequent as system components get older.

Drought news: C-BT water is commanding a premium price this dry season #COdrought

usdroughtmonitorjuly22013.jpg

From The Greeley Tribune (Eric Brown):

The price for a share of northern Colorado’s largest water-supply project has nearly doubled just this year, and such upswings in prices create a tough situation for anyone in the agriculture industry who’s needing more of the resource. In January, a unit of the Colorado-Big Thompson Project was selling for $9,500, but last month units sold for as much as $18,500, according to officials at the Northern Colorado Water Conservancy District, who oversee operations of the C-BT Project’s 12-reservoir system.

Brian Werner, a spokesman and historian who’s been with Northern Water for more than 30 years, said the recent price marks an all-time high for C-BT Project shares, and added that one would have to go back to the mid-1980s to find a time when the price of a C-BT unit doubled within one year.

Water experts in the region say the skyrocketing water prices are partly attributed to recent profitability in agriculture and farmers’ increased reluctance to sell their water rights. Seeing less farmers sell their water is good news for northern Colorado’s robust agriculture industry, which has watched its ownership of water decline over the years.

However, the resulting minimal amount of water on the market is pushing already high prices to a point where farmers could have even more trouble affording water if they’re looking for it. “It’s certainly not farmers who are paying these high prices right now,” Werner said.

For years, farmers have sold their water to growing cities in the region, either because they were retiring from farming and didn’t have children taking over operations, or because they were pursuing other careers, since farming wasn’t profitable at the time. That’s not the case anymore. Increased demand for corn and other agricultural goods — stemming from droughts and upswings in biofuel production and food demand abroad — has led to higher commodity prices, and recently to some of the best income years in decades for many farmers and ranchers.

Because of that, producers still in the agriculture game want to stay in it, and they’re hanging on tighter to their water. Local water officials say growing cities in Colorado are still buying water, but there’s much less of it to buy anymore.

“From my understanding, cities have already picked the low-hanging fruit,” said Randy Ray, executive director with the Central Colorado Water Conservancy District in Greeley, which provides water to farmers in three counties. “For a long time, there were plenty of farmers wanting to get out of agriculture and were eager to sell their water to cities. There’s not many of those farmers left now.” Ray, who’s constantly in search of more water for farmers in his district, said prices for other water sources haven’t increased as much as the Colorado-Big Thompson Project.

But he added that water certainly isn’t getting cheaper anywhere. “The price everywhere is only going to keep climbing, so that’s why we’re trying to buy it now, before it gets too expensive,” Ray said of Central Water, which last fall passed a $60 million bond issue in order to increase its water supplies. “In the early 1980s, digging new gravel pits for water storage cost us about $200 per acre foot. Now it’s about $3,000 per acre-foot. “Thirty years ago, water shares were in the hundreds of dollars. Now you’re probably paying $10,000, anywhere you look.”

Werner noted that a recent upswing in home building in northern Colorado might be adding to the demand and price of C-BT water. The region’s oil and gas production is skyrocketing, and could also be contributing some to C-BT’s water-price increases. But, as Werner noted, the oil and gas industry uses less than 1 percent of the state’s water, so that industry’s increased demand can only impact things so much. “It still probably just comes down to agriculture users not wanting to sell it anymore,” Werner said.

C-BT water flows to more than 640,000 acres of irrigated farm and ranch land and about 860,000 people in portions of eight counties, according to Northern Water. When the C-BT Project went it to full use in 1957, 85 percent of its water was owned by agriculture users. Agriculture’s ownership of the C-BT Project has fallen since then to 34 percent.

Overall, agriculture still uses much of the state’s water — 85 percent — and does so in large part by renting water from cities. However, in drought years particularly, renting water isn’t always a reliable source. In dry times, cities are more reluctant to lease water to farmers and ranchers. And as cities in northern Colorado continue to grow and their water supplies become more stretched, they’re expected to lease even less water to agriculture.

Because of that, agricultural users have stressed the need to buy more of their own water supplies. But the sky-rocketing price is making it difficult for Ray and others who are trying to buy water on behalf of agriculture. “The prices certainly aren’t making things any easier,” Ray said. “But we’ll keep looking.”

From The Denver Post (Howard Pankratz):

The drought that has scorched the state is sending hay prices skyward and forcing horse owners to make painful decisions. Many owners, who struggled to keep their horses through the economic downturn, are giving up their animals — either selling them for a pittance, euthanizing them or sending them to Mexico or Canada for slaughter.

“The drought has really decreased the amount of hay,” said Scot Dutcher, chief of Colorado’s Bureau of Animal Protection. “It is basically simple economic rules of supply and demand. When the supply is high, the price goes down. But when the supply is low, obviously the price goes up — and it went way up.”

The price of hay in Colorado, which once was $120 a ton, now ranges from $250 to $350 a ton, Dutcher said…

Over the course of the past year, Wallden has gotten rid of three of her horses, placing two on what she and other owners refer to as “the killer truck” to be sent outside the U.S. for slaughter, while a third was sold at auction, a purchase she suspects was also for slaughter. Because of the drought, Wallden said she can no longer grow hay on her Kiowa property and can’t keep up with the rising prices being charged by other growers.

Glen Canyon Institute: Top off Lake Mead lower Lake Powell to obviate water loss #ColoradoRiver

Here’s an in-depth look changing operations for the two big reservoirs on the Colorado River mainstem, from Bob Berwyn writing for the Summit County Citizens Voice. Click through and read the whole post. Here’s an excerpt:

The porous sandstone along the shore of Lake Powell may soak up as much as 380,000 acre-feet of water each year — more than Nevada’s entire annual allocation of Colorado River water, according to a new study by hydrologist Thomas Myers.

The research, published in the Journal of the America Water Resources Association, supports the idea of reconfiguring the way water is stored in Lake Powell and Lake Mead with the overall goal of using the Colorado River in the most efficient way possible, according to Glen Canyon Institute director Christi Wedig.
