From Water Education Colorado (Jerd Smith):

Despite the recent history-making blizzard on Colorado’s Front Range, statewide snowpack sits at 92 percent of average as of March 19, down from 105 percent of average at the end of February, according to the Natural Resources Conservation Service.

Just two river basins, the Arkansas and the Rio Grande, are registering above average at 101 percent and 106 percent respectively. Among the driest are the Gunnison Basin, at 86 percent of average, and the San Juan/Dolores, at 83 percent, both in the southwestern part of the state.

“The snowpack numbers are still below normal though they don’t look that bad,” said Peter Goble, a specialist with the Colorado Climate Center at Colorado State University. “But based on how dry soils were to start this accumulation season, we’re still pretty nervous about what water availability is going to look like.”

Those numbers are hard to believe for some, given that nearly 30 inches of snow fell in and around Denver the weekend of March 13, with some portions of the foothills and higher receiving more than three feet of snow. It is considered the fourth-largest storm in Denver’s history.

According to the U.S. Drought Monitor, the entire state remains mired in drought, with nearly half classified as being extremely or exceptionally dry, the most dangerous categories.

Mountain snowpack is watched closely in Colorado and other Western states because as it melts, it fills rivers and reservoirs to supply the state’s cities, farms and industries with water for the coming year.

Thanks to 2020’s severe drought, in November, for only the second time in its history, the Colorado Water Conservation Board activated its municipal emergency drought response plan in an effort to help cities cope with the dry conditions.

As part of that effort some 14 metro area cities have agreed to coordinate how they inform community members of potential drought restrictions.

“The biggest thing is we don’t want to be counter-messaging anybody,” said Greg Baker, spokesperson for Aurora Water. Aurora is one of the members of the new drought coordination group. “Towns that have robust storage like Denver and Aurora may not need restrictions. But there are about 50 water utilities across the Front Range.”

Those that don’t have hefty storage systems might have to declare drought emergencies, as many did in 2012 and 2013, Baker said.

And when, for instance, major TV stations broadcast that there are no restrictions in Denver or Aurora, it makes it difficult for communities that have to impose limits to help customers understand the vast differences in drought response, he said.

How this year will play out isn’t clear yet, Baker said. Aurora’s reservoirs are at 63 percent of capacity, the low end of normal. Aurora draws its water from the mountains in the Arkansas, Colorado and South Platte river basins.

“A lot of customers forget that we may have had some good snow down here but that is not where we collect our water. It happens up in the mountains,” Baker said.

Even as mountain snows approach the average mark, soils remain dry and therefore capable of absorbing much of the snow that will melt in the spring.

“We’re getting reports that soil moisture is 10 inches below normal,” Baker said. “Will runoff be sucked up? We don’t know.”

Of particular concern to hydrologists and water watchers across Colorado is the forecast for the seven-state Colorado River Basin. The river begins high in Rocky Mountain National Park and, together with tributaries in Colorado like the Gunnison, Yampa, and Dolores rivers, it supplies all of the state’s Western Slope’s water as well as roughly half of the water for Front Range cities and tens of thousands of acres of farms in the Eastern Plains.

As it flows south and west, the river supplies not only Colorado but also Wyoming, Utah and New Mexico, a region known as the Upper Basin, and Nevada, Arizona and California, known as the Lower Basin. It also supplies Mexico.

The basin has two major storage reservoirs in the U.S. and they are filled almost entirely from the mountain snows generated in the Upper Basin. The forecast for the basin remains grim, with the U.S. Bureau of Reclamation estimating that Lake Powell will see inflows of just 47 percent of average as of March 3, the most recent data available.

According to Reclamation, the last half of 2020 was one of the driest periods on record in the Colorado River Basin, and closely resembles the deep droughts of 2002, 2012, 2013 and early 2018. These are, according to the March 3 report, four out of the five driest years on record.

Levels in Powell and Mead are likely to drop low enough this year to trigger additional cuts in water deliveries to Lower Basin states. The recent blizzard in Colorado, because it did not benefit Colorado’s Western Slope and the headwaters of the river as much as it did the Eastern Slope, aren’t likely to change that, according to Reclamation.

From The Glenwood Springs Post-Independent (John Stroud):

Unfortunately, recent snowstorms did very little to improve the mountain snowpack. And the near-term prediction for measurable precipitation isn’t promising.

That’s according to several sources of data and predictive models tracked by the USDA Natural Resource Conservation Service Colorado Snow Survey Program.

NRCS Hydrologist Karl Wetlaufer noted in his monthly snowpack report issued March 5 that, “While February snow accumulations did improve the snowpack in many parts of the state, snowpack still remains below normal levels in all major basins except the Rio Grande.”

At that time, the Colorado River Basin was at 84% of median snowpack, and just 71% of last year’s snowpack. Statewide, the median snowpack at that time was 85%, and only 77% of last year.

Then came the big one — sort of.

A major snowstorm the weekend of March 13 that mostly blanketed the the foothills and eastern Colorado with up to 2 feet of snow in places did have some impact on the high country snowpack. When it comes to Western Slope water, that’s where it mostly matters.

Just before that storm hit, on March 10, the Colorado River Basin was at 88% of median snowpack.

Likewise, one of the Colorado’s major drainages, the Roaring Fork River, with its headwaters on Independence Pass east of Aspen, was at 84% of median.

Afterwards, the area basin snowpack had improved to 91% and 90%, respectively.

As of Tuesday, with more localized snowfall in recent days, the Roaring Fork drainage had improved to 94% of median.

The summer and fall of 2020 was one of the driest periods on record in Colorado.

“This led to dry soil moisture conditions and the expectation is that snowmelt runoff will produce lower volumes than would commonly be observed with a similar snowpack,” Wetlaufer observed in his March 5 report.

Before winter even started, snow forecasters were saying Colorado would need multiple years of 150% to 200% of normal snowpack to improve the drought situation…

“There is currently a significant soil moisture drought that will consume a greater-than-average amount of snowmelt runoff, and leave less to streamflow runoff,” [Brian Domonkos] said. “To add to the complexity, low soil moisture means lower base flows in rivers and streams, which means more precipitation is needed to bring stream flows back to normal levels.”

#Drought news (March 25, 2021): Frequent precipitation during the past two weeks continues to result in additional improvements to parts of the central Plains and central Rockies

This Week’s Drought Summary

A couple of low pressure systems resulted in widespread precipitation (0.5 to 3 inches, locally more) across the central and southern Plains, Ohio and Tennessee Valleys, Southeast, and Mid-Atlantic from March 16 to 22. However, mostly dry weather persisted across southern Texas, the Florida Peninsula, northern New England, the Great Lakes, and northern Plains. Periods of rain and high-elevation snow occurred across the Pacific Northwest, northern California, and the central Rockies, but the Southwest remained mostly dry. As of March 23, 7-day maximum temperatures averaged above normal across the northern Plains and Upper Mississippi Valley…

High Plains

Frequent precipitation during the past two weeks continues to result in additional improvements to parts of the central Plains and central Rockies. 7-day total amounts (March 16-22) ranged from 1 to 3 inches, locally more, across a broad region including south-central Nebraska and much of Kansas. As of March 22, Grand Island Nebraska has received 6.95” so far this month which makes it the wettest March on record. The drought amelioration extends west to the central Rockies where numerous improvements were made including a two-category change from D3 to D1 in southwest El Paso County and southeast Teller County as SPIs are now D1 at all timescales. The removal of D3 in southeast Colorado and southwest Kansas was based on: SPIs are either neutral or positive dating back to 6 months and improving soil moisture conditions. In contrast to the major improvements across the central Rockies and central Plains during the past two weeks, persistent dryness continues to support additional expansion of D2 (severe) and D3 (extreme) drought across parts of North Dakota…

West

A slight expansion of severe drought (D2) was made to northeast Montana, based on 90-day SPI and soil moisture below the 10th percentile. These low soil moisture conditions are related to the lack of snowfall this winter. In contrast to the northern high Plains, snow water content is running close to average for late March and led to the elimination of abnormal dryness (D0) across south-central Montana. Since parts of western Arizona and southeast California have received little to no precipitation during the past two month, D3 (extreme) and D4 (exceptional) drought were slightly increased. This expansion of D3-D4 was supported by 9-month SPI values which covers the failed 2020 monsoon and this past winter. An expansion of D2 (severe) and extreme (D3) drought across parts of southern California was based on large water year to date precipitation deficits and 6-month SPI values. No other changes were made at this time to the remainder of California as 6 to 12 month SPIs generally support the current depiction and snow water content is running near two-thirds of average for the Sierra Nevada Mountains. During subsequent weeks, the drought depiction will be reassessed across California. Although much of the precipitation this past week fell along the coast or over the Cascades, a reassessment of longer term SPIs dating back 6 to 12 months supported removal of the D2 (severe) drought in southwest Oregon. Due in part to recent high-elevation snow and rainfall during the past two weeks, a slight decrease in D3 (extreme) and D4 (exceptional) drought was made to northern and northeast New Mexico. However, widespread D4 persists across southeast New Mexico where dust storms have been quite frequent this month and soil moisture remains in the lowest one percentile…

South

The severe weather outbreak that affected the Southeast Region began across the Lower Mississippi Valley on March 17 and local rainfall amounts exceeded 2 inches across parts of Arkansas, Louisiana, and Mississippi where 1-category improvements were made. More widespread rainfall amounts of more than 1.5 inches increased soil moisture throughout nearly all of Tennessee. Based on this past week’s rainfall of 1 to 3 inches and improving soil moisture conditions, improvements were made to much of Oklahoma and parts of northern to central Texas. Small 2-category improvements were justified for the northeast Texas Panhandle and northwest Oklahoma where the heaviest rainfall occurred. Periods of above normal temperatures, enhanced surface winds, and below normal precipitation this month supported a continued worsening of drought conditions throughout southern Texas. Soil moisture declines rapidly from central to west Texas where indicators support D3 (extreme) to D4 (exceptional) drought categories…

Looking Ahead

During the next 5 days (March 25 to 29), a pair of low pressure systems are forecast to bring widespread precipitation (0.5 to 2 inches, locally more) to the Lower and Middle Mississippi Valley, Ohio and Tennessee Valleys, and Northeast. Farther to the south across the Florida Peninsula and southern Texas, dry weather is likely to persist. Little to no precipitation is also forecast for the northern Great Plains. Additional snow is expected throughout the Rockies, Intermountain West, and Cascades.

The CPC 6-10 day extended range outlook (valid from March 30 to April 3) favors near normal temperatures for much of the lower 48 in a variable pattern. Probabilities of above normal temperatures are elevated for the northern Plains, Florida, and California. Below normal temperatures are most likely across Alaska. Above normal precipitation is favored for the Northeast, Mid-Atlantic, western Gulf Coast, Rio Grande Valley, and Alaska. Increased chances of below normal precipitation are forecast across the Upper Mississippi Valley, much of the Plains, and throughout the West.

#OgallalaAquifer Depletion: Situation to Manage, Not a Problem to Solve — No-Till Farmer

Center pivot sprinklers in the Arikaree River basin to irrigate corn. Each sprinkler is supplied by deep wells drilled into the High Plains (Ogallala) aquifer.

Here’s a guest column from Kay Ledbetter, Texas A&M that’s running in No-Till Farmer:

The Ogallala Aquifer’s future requires not just adapting to declining water levels, but the involvement of a wide range of participants comfortable with innovation who will help manage the situation and drive future changes.

That was the message heard by more than 200 participants from across eight states who listened in and identified key steps in working together during the recent two-day Virtual Ogallala Aquifer Summit. The event was led by the U.S. Department of Agriculture-funded Ogallala Water Coordinated Agriculture Project, CAP, which includes Texas A&M AgriLife.

The group partners with the Kansas Water Office and USDA’s Agriculture Research Service-supported Ogallala Aquifer Program to coordinate this event with additional support from other individuals from all eight states overlying the Ogallala Aquifer.

“Technological innovation, financial and economic conditions, infrastructure changes, social values – all these factors drive change,” said John Tracy, Ph.D., director of the Texas Water Resources Institute, which is a partnering agency in the Ogallala Aquifer Program.

Often people feel the need to solve the issue of declining groundwater across many parts of the aquifer, when in fact, what is needed is to look at how we manage change, Tracy said. Adaptive management is about driving the change — realizing it is coming and trying to affect what is happening rather than just responding.

“So, large regions of the Ogallala are going to run out of water, particularly in the Southern High Plains – how are we going to embrace that and not just respond to the change?” he said. “Two important factors: first, this summit; have productive and transparent dialogue to move forward.

“The second thing we need to embrace is rethinking how we approach the changes happening in the Ogallala — this is not a problem to be solved; this is a situation to be managed. We must move into the mindset of changing programs in order to get out in front of the situation. One of the most important activities is looking forward to how we drive this conversation and turn talk into action through consensus building that is the product of shared dialogue amongst all of us.”

Meeting of the Minds

An inaugural eight-state summit, led by the Ogallala Water CAP and Kansas Water Office in 2018 focused on what actions were happening or could happen in terms of field management, science and, to some extent, policy.

After the 2018 summit, participants across the eight states helped lead the integration and merging of technology, the expansion of the Master Irrigator program into more states, as well as the development of new policies and incentives to support more conservation and other collaborative efforts. These efforts are helping develop a broader understanding of actions needed to address the region’s critical water issues.

The 2021 summit was intentionally framed to engage a broader community of actors.

Joining the conversation were representatives of energy co-ops, lenders, producers, federal agencies in each state, youth, non-profits, policymakers, commodity groups, tech and irrigation equipment dealers and multinational companies. Participants identified other groups, including absentee landowners and tribal representatives, that should be invited and engaged as a focus area of the conversation at a future summit event.

Key messages that surfaced from the two days of conversations were:

– Change is imperative to be sustainable. You must be adaptive, not reactive. Transition takes time.

– Learn from each other using inter-regional, interstate and peer-to-peer planning.

– Be willing to experiment with new ideas.

– The power of data drives good policy and real-time decision making for producers and helps break down silos.

– Water is a basic critical infrastructure; we need enough water to support our rural economy, but all industries are dependent on water and it affects the overall economy.

– Producers carry the brunt of what we talk about financially, and keeping them profitable as long as possible must be a priority.

– Engage and invest in youth. Invite them to join and foster conversations that instill a conservation mindset not just among their peers but with a wide range of stakeholders.

Changing the Mindset

The path forward begins with creating interest and providing education to the next generation of both producers and water conservation leaders. Fostering the transfer of knowledge between generations and developing leadership skills to position youth to step into groundwater district and other community leadership roles will be key.

David Smith, 4-H2O program coordinator with the Texas A&M AgriLife Extension Service, Bryan-College Station, described how the Texas 4-H Water Ambassadors program is creating water stewardship leaders.

The program provides an opportunity for youth to gain insight into water law, policy, planning and management, and potential career paths as they interact with representatives from state water agencies, educators, researchers, policymakers and water resource managers.

But education must also take place in the fields. It must provide an organized pathway where producers can find actions and dedicate the time needed to make a difference. Producer-to-producer learning approaches in partnership with university and industry, such as the Nebraska and Oklahoma Testing Ag Performance Solutions program, have been particularly effective.

Brent Auvermann, Ph.D., summit program chair and Texas A&M AgriLife Research and Extension Center director, Amarillo, said the adoption of technology can’t be taken for granted. Looking ahead, tech development and research must grapple with the human dimension of technology adoption.

“Technology will race ahead, but it will stay on the shelf until and unless we devise new ways to foster its adoption,” Auvermann said. “Using even a little bit more water than needed is a form of crop insurance and asking producers to rely on new technology to cut back on that water use increases the risk that they, their insurers and their lenders perceive.”

C.E. Williams, Panhandle Groundwater Conservation District general manager, White Deer, said when producers think about growing a crop, their concern shouldn’t be about bushels per acre — water is the limiting factor. They need to understand and invest in the technology that will ensure they are putting every drop in the right place.

“All the inputs you put in are important, but the bottom line is water,” Williams said. “Why did we use it? It is like money. You spend it; it is gone. What was your bottom line per water use? Rather than thinking of production in terms of bushels per acre, we should be thinking in terms of how many bushels per acre-inch or acre-foot of water used.”

Every drop saved adds up

We need to find a way to provide access to broad audience about the actions of many successful innovators who are having success with different precision management technologies and strategies, said Chuck West, Thornton Distinguished Chair in the Texas Tech University Department of Plant and Soil Science, Lubbock.

“There are a lot of little decisions that people can make all along the way that add up to considerable water savings,” West said.

Katie Ingels, director of communications with the Kansas Water Office, said several some of their Water Tech Farm producers are seeing the advantages of tech adoption, where a combination of slight adjustments in practice or integrating a new tool or strategy and related decisions each contribute some savings of money, time or water.

“There’s a mindset out there among some growers that they can’t make a tremendous difference because they are a smaller operation with only a few wells,” said panelist Cory Gilbert, founder of On Target Ag Solutions. “Every single system that adds to the acre-foot savings turns into a very big number very quickly in terms of conservation.”

Panelist Matt Long, producer and seed supplier, Leoti, Kansas, said water conservation is a quality of life issue.

“If you look at the communities you can see which ones are vibrant and they are the ones with a stable water supply that can support industry beyond cropping,” Long said. “Conserving water isn’t just about there being water for the future; it’s about having a community for the future. We have to have enough water to keep the people to keep the community.”

But at the same time, Auvermann said, communities need to be mindful of their water use.

“We city folks need to look no further than our front lawns to see why we’re in the pickle we’re in,” Auvermann said. “We run water down the curb to make sure our home’s appearance doesn’t suffer. Water is insurance for all of us.”

Building a Path Forward

Amy Kremen, Ogallala Water CAP project manager, Department of Soil and Crop Sciences at Colorado State University, said a continuing theme throughout the meeting was, “With limited water in the High Plains, the question is less about production that needs to feed the world’s population of 8 billion, it’s about keeping rural communities vital. We need to give people more flexible options that allow them to make decisions related to water use that are to their economic best advantage.”

Quality of life in these smaller communities, whether they are in Kansas or Texas or any of the states the Ogallala Aquifer supports, is what is important.

“We don’t want to dry up that life,” Kremen said. “We are all in this together. And together, we will come up with solutions better than any of us individually.”

Decisions must center on making conservation economical for agriculture producers, both short-term and with long-term sustainability, providing not only for the next generations on the farm, but for the sustainability of the local communities they support.

“We need to be willing to have uncomfortable conversations,” Auvermann said. “We need to talk candidly and be willing to entertain new, unfamiliar ideas. Sometimes we’ll make mistakes, but it’s not as though we’ve not been making them up to this point. Fear of making mistakes keeps us from innovating. Our dialogue has to be generous, congenial and optimistic to overcome that. We have to be trustworthy ourselves, and we have to be willing to trust.”

People are hungry to have these conversations, said Meagan Schipanski, Ph.D., associate professor, Department of Soil and Crop Sciences at Colorado State University and Ogallala Water CAP codirector.

“We need to have them happen in public, mini-summits or regional conversations,” Schipanski said. “We need to take on a stewardship that meets producer and community needs.”

Panelists duel over fluoridation of Loveland water; commission votes to continue program — The #Loveland Repoter-Herald

Colorado and Southern depot back in the day via LovelandHistorical.org

From The Loveland Reporter-Herald (Max Levy):

Skeptics and public health officials dueled over the issue of water fluoridation during Wednesday’s meeting of the Loveland Utility Commission, which last heard similar concerns in 2014.

The skeptics failed to sway the commission, however, which voted at the suggestion of Loveland Water and Power director Joe Bernosky to recommend the city continue its practice of water fluoridation.

An anti-fluoridation panel spoke first, led by Traudl Renner, whose comments before the City Council in October prompted the meeting. She argued that emerging science has called into question the safety of fluoridation, which Loveland has undertaken since 1954.

She cited a study that indicated fluoride could damage the immune system (a panelist supporting fluoridation qualified this by saying the quoted section considered very high doses of the element)…

She also questioned the effectiveness of ingested fluoride in preventing tooth decay, which is the reason why communities such as Loveland introduce fluoride compounds into their water.

Renner and fellow anti-fluoride panelist Kathryn Jordan also brought up how accidents at water treatment facilities occasionally cause dangerous amounts of fluoride to be introduced into drinking water.

Joe Bernosky, director of Loveland Water and Power, later said he and water utilities manager Roger Berg were not aware of any such accidents having ever occurred in the city.

Jordan questioned the expense of programs such as Loveland’s, and asked why the city wouldn’t receive the chemical, which she said is the byproduct of certain industrial processes, for free…

Chris Neurath, research director for the American Environmental Health Studies Project, said studies also suggest the element is neurotoxic and notably dangerous for pregnant women and young children…

Neurath’s characterization of multiple studies was challenged by fluoridation advocates, particularly pediatrician Patricia Braun and dentist William Bailey of the University of Colorado’s Anschutz Medical Campus. The latter called water fluoridation an “ideal public health measure.”

“There’s nothing that you have to remember to do,” he said. “You don’t have to make an appointment. You don’t have to stand in line. You don’t have to go to the doctor. All you have to do is drink and use the water. It’s inexpensive. It helps tremendously with dental disease.”

“Community fluoridation is the most cost-effective and far-reaching strategy we have to prevent cavities,” Braun said, adding that tooth decay was the number one reason she saw children going into surgery.

Braun and Katya Mauritson, the Colorado Department of Public Health and Environment’s dental director, also spoke about the savings in medical expenses seen by communities that fluoridate their water, with Mauritson estimating that Loveland’s program saves residents more than $2 million in medical bills every year.

Commissioners voted unanimously to recommend the city keep up its water fluoridation program.
