Colorado Ski Area Water Rights and USFS

July 14, 2014

Originally posted on Your Water Colorado Blog:

Colorado ski areas got some “fresh powder” in late June in the form of a proposed US Forest Service water rights rule that backs away from an earlier and much criticized approach that would have required ski areas to transfer water rights to the agency.

The new rule, proposed June 23 and open for comment through August 22, would amend internal USFS directives for some 122 ski area concessions across the country by instead conditioning their 40-year special use permits on a commitment that sufficient water stay dedicated to ski area operations even if the area is sold. Under the proposal, permits would be updated as they are renewed to include the water rights commitment language. Currently, USFS policy requires the public hold the rights to such water, but the proposed change would allow water rights to be in the name of the permit holder.

FRISCO — A warmer and wetter atmosphere is likely to drive up the number of severe thunderstorms in coming decades, potentially resulting in more economic losses associated with extreme weather.

The new study led by Stanford University scientists shows  that global warming is likely to cause a robust increase in the conditions that produce these types of storms across much of the country over the next century, including more severe weather during the spring, fall and winter.

To date, efforts to project thunderstorm activity under various global warming scenarios has been hampered by sparse historical data. But the Stanford-led team, headed by professor Noah Diffenbaugh, was able to use a complex ensemble of physics-based climate models to produce the most comprehensive projections of…

Staff Report

FRISCO — Humankind’s out-of-sight, out-of-mind attitude about garbage is slowly but surely turning the world’s oceans into a soup full of microscopic plastic particles that are probably passing into the marine food chain, Spanish scientists said this week, describing their findings from a nine-month research cruise around the world.

“Ocean currents carry plastic objects which split into smaller and smaller fragments due to solar radiation,” said Andrés Cózar, aresearcher with the University of Cadiz. “Those little pieces of plastic, known as microplastics, can last hundreds of years and were detected in 88 percent of the ocean surface sampled during the 2010 Malaspina Expedition,” Cózar said.

From email from Reclamation (Kara Lamb):

It looks like Ruedi Reservoir is inches from completely full. Last night at midnight, the reservoir’s total content was about 98.8%. Tonight’s reading will likely be around 99% full. As a result, tomorrow, Sunday, releases from the dam to the Fryingpan River will bump up another 50 cfs. We will make the change around 8:00 a.m. After that, flows past the Ruedi Dam gage will be closer to 321 cfs.

Make Water Provocative: Measuring Effectiveness

When we present interpretive programs, what do we ultimately hope to accomplish?  The answer is often that we hope to change people’s minds and behaviors.  Perhaps we want them to feel concern about water shortages and use less water.  Perhaps we want them to appreciate Colorado water law and therefore vote a certain way.  Perhaps we just want them to care about water and make decisions with water in mind.  Regardless, interpreters must (1) determine their goals and (2) set objectives by which to measure their effectiveness.

Click here for the Wikipedia entry. Here’s an excerpt:

John Laing Leal (1858–1914) was a physician and water treatment expert who, in 1908, was responsible for conceiving and implementing the first disinfection of a U.S. drinking water supply using chlorine. He was one of the principal expert witnesses at two trials which examined the quality of the water supply in Jersey City, New Jersey, and which evaluated the safety and utility of chlorine for production of “pure and wholesome” drinking water. The second trial verdict approved the use of chlorine to disinfect drinking water which led to an explosion of its use in water supplies of the U.S.

“…the American people expect us to act on the facts” — Gina McCarthy

Summitville Mine superfund site

Summitville Mine superfund site


From the National Journal (Jason Plautz):

Environmental Protection Agency Administrator Gina McCarthy fired back in the war over her agency’s science, slamming critics who “manufacture uncertainties that stop us from taking urgently needed climate action.”

The agency’s scientific studies have become an increasingly convenient target for industry groups and congressional Republicans bent on stopping EPA regulations. Republicans have subpoenaed several health studies that EPA relies on for its air-pollution rules, and increasing attention has been heaped on the agency’s scientific review panels.

Speaking at the annual meeting of the National Academy of Sciences on Monday, McCarthy went after the “small but vocal group of critics” who she said were more interested in “looking to cloud the science with uncertainty … to keep EPA from doing the very job that Congress gave us to do.”

McCarthy also touched on the agency’s controversial use of human testing to measure the impact of air pollution, the subject of a recent Inspector General report that largely said the agency followed proper procedure. Critics have said that the human tests put the subjects at risk.

In her speech, McCarthy countered that the human tests helped scientists to “better understand biological responses to different levels of air pollutants.”

“Science is real and verifiable,” she said. “With the health of our families and our futures at stake, the American people expect us to act on the facts, not spend precious time and taxpayer money refuting manufactured uncertainties.”


7 Reasons Water-Lovers Should Visit the “Living West” Exhibit at History Colorado

Colorado’s challenging environment has shaped the state’s history and its people, and perhaps the greatest shaping factor has been water.  Water has largely determined where people lived and how they survived, and water continues to challenge Coloradans today.  The Living West exhibit at History Colorado invites visitors to explore three water-related chapters of Colorado’s history:  Mesa Verde, the Dust Bowl, and Colorado’s Mountains. Water abundance and shortages shape all three episodes. The residents of Mesa Verde harnessed water for crops and livestock, only to experience severe drought; drought, fragile soil, volatile prices, and debt devastated many Baca County farms in the 1930s; and today we see many environmental changes in the mountains while we struggle to provide enough water for all.

Water has many different meanings, and means many different things to different people. The goal of water interpretation is to reveal these meanings, to facilitate connections between people and water – perhaps even to illuminate new ones.  But for this to happen, the interpreter must relate the resource to the audience’s own experience – and one of the most effective ways to do this is to use universal concepts.

Solar activity only a minor factor in global warming

At most, solar cycles have contributed no more than 10 per cent to global warming in the last century. The findings, made by Professor Terry Sloan at the University of Lancaster and Professor Sir Arnold Wolfendale at the University of Durham, find that neither changes in the activity of the Sun, nor its impact in blocking cosmic rays, can be a significant contributor to global warming.

Changes in the Arctic likely to have widespread hemispheric impacts

By Summit Voice

FRISCO — A new climate study by scientists at the University of Exeter (UK) adds to the growing body of research looking at the hemispheric impacts of dwinding Arctic sea ice.

The findings suggest that that the loss of ice shifts the jet stream farther south, bringing increased summer rainfall to northwestern Europe, but drier conditions to the Mediterranean region. The study could offer an explanation for the extraordinary run of wet summers experienced by Britain and northwest Europe between 2007 and 2012.

In another recent study, scientists with the Cooperative Institute for Research in Environmental Science found that as sea ice disappeared, the areas of relatively warm open water began to strongly influence the atmosphere, increasing surface temperatures in the region, and…

FRISCO — After radiocarbon dating samples of moss at the edge of melting ice caps on Baffin Island, scientists said there’s little doubt that current warming in the Arctic is unprecedented, even on a geological time scale.

Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher than during any century in the past 44,000 years and perhaps as long ago as 120,000 years, according to a University of Colorado Boulder study.

“The key piece here is just how unprecedented the warming of Arctic Canada is,” said CU-Boulder geologist

SUMMIT COUNTY — Long-time skiers often say that skiing was better in the good old days, and new research from the U.S. Geological Survey suggests that those claims are based on more than nostalgia — notwithstanding the occasional bumper crop of powder like in 2010-2011.

After taking an in-depth look at snowfall and temperature records, federal scientists said warmer spring temperatures since the 1980s have caused an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America — especially at lower elevations where temperatures have the greatest effect.

Winter browsing by elk results in decline of habitat for songbirds

Dwindling Rocky Mountain snowpack is having unexpected impacts to a wide range of plants and animals, according to a new study.

By Summit Voice

SUMMIT COUNTY — A steady decline in Rocky Mountain snowpack the past few decades has led to a classic cascading ecological effect, with “powerful” shifts in mountainous plant and bird communities, according to scientists with the U.S. Geological Survey and the University of Montana.

“This study illustrates that profound impacts of climate change on ecosystems arise over a time span of but two decades through unexplored feedbacks,” said USGS director Marcia McNutt. “The significance lies in the fact that humans and our economy are at the end of the same chain of cascading consequences.”

As the high-elevation snowpack dwindles, elk can stay at higher elevations during the winter and browse on plants that just a few short decades were inaccessible during the snow season, the researchers explained in their study, published Jan. 8 in…

FRISCO — Rainfall amounts in the tropics may be influenced by ocean currents originating thousands of miles away, in polar regions, according to an international team of climate scientists trying to track down how global warming might affect precipitation in different regions.

Most tropical rains fall in the northern hemisphere — Palmyra Atoll, at 6 degrees north, gets 175 inches of rain a year, while comparable locations at similar latitudes south of the equator only get 45 inches annually.

Scientists have long thought that this was due to a quirk in the Earth’s geometry — with the spin of the Earth pushing tropical rain bands north across diagonally tilted ocean…

FRISCO — Some chilly and soggy October days are giving a clear indication that we’re rapidly slipping into our cold season. That’s not to say we won’t have a few weeks of Indian Summer going into the second half of what is usually our driest month. But for now, button up, grab your beanie and head out to enjoy the last few days of changing aspen leaves — Farewell, autumn, we hardly knew you!

When H2O Outdoors began four years ago, I never imagined we would have the partners and diversity of students that are in the program today. By being open to any high school student in Colorado, the program brings in a wide variety of perspectives that contribute to the overarching process of learning from each other, collaborating in a fictional decision-making process, and helping students learn the ways adults in the water field must work together to solve complex water problems throughout the state.

    September Precipitation and Temperatures, and Current Drought

    September ended the 2013 water year on a very wet note across the region, with most of the region receiving at least 200% of normal precipitation, and only a few small areas seeing drier-than-normal conditions Western US Seasonal Precipitation. The last month with comparable wet anomalies across the region was December 2007. A persistent rain event from September 9th–17th, caused by a late monsoonal surge from the south reinforced in eastern Colorado by very moist upslope flow, brought most of the month’s precipitation, including extraordinary totals for Boulder, Colorado (9″ in 24 hours; 17” in seven days) and the surrounding area. (See the WWA’s preliminary assessment of the Front Range rain event and the severe flooding it caused.)

    Other areas with over 5” of precipitation for the month included far southeastern Wyoming, south-central Utah, the Uinta Basin in northeastern Utah, the southeastern Yellowstone Plateau, and the San Juans in southwestern Colorado.

    With this late surge, the final HPRCC Water Year Precipitation map Western US Seasonal Precipitation for 2013 showed that the previously scattered areas with above-average precipitation since October 1 have enlarged and merged, covering perhaps one-third of the three-state region, with the wettest areas in northeastern Colorado, southern Utah, and northern Wyoming. But, as in the 2012 water year, most of the region still ended up drier than normal.

    Despite all the precipitation, the temperatures in SeptemberWestern US Seasonal Precipitation were warmer than average across the region, except in parts of western Utah and western Colorado. Most areas were 1–6°F above monthly average temperatures for September.

    The latest US Drought Monitor, representing conditions as of October 1 Modeled Soil Saturation Index, shows significant and widespread improvement in the persistent drought conditions, by one to three categories, compared to one month ago. The most dramatic improvements were in northeastern Colorado, where up to D2 drought conditions were brought to normal, and in southwestern Colorado, where D3 drought improved to D0 Modeled Soil Saturation Index. The proportion of Colorado in D2 or worse drought dropped from 60% on September 3 down to 12% on October 1; in Utah, 54% down to 16%; and in Wyoming, 48% to 22%. Region-wide, the overall drought extent and severity is now lower than it has been since April 2012.

    By Summit Voice

    FRISCO — The current spruce beetle outbreak in Colorado’s high country has the potential to grow larger in scope than the recent mountain pine beetle epidemic that killed mature lodgepole pines across millions of acres.

    And the trigger of for the spruce beetles is drought that’s linked with long-term changes in sea-surface temperatures in the Northern Atlantic Ocean, a trend that is expected to continue for decades, according to a new study by scientists with the University of Colorado, Boulder.

    The new study is important because it shows that drought is a better predictor of spruce beetle outbreaks in northern Colorado than temperature alone, said Sarah Hart, a CU-Boulder doctoral student in geography.

    Toxic materials a concern for freshwater ecosystems

    By Summit Voice

    FRISCO — By now, everyone has heard about the giant ocean eddies of plastic debris — the final resting place, as it were, for the detritus of our throw-away society. As it turns out, the ocean isn’t the only place that’s been polluted by human thoughtlessness.

    German scientists say their recent study of Lake Garda, a subalpine lake at the southern edge of the Italian Alps, is also polluted with potentially hazardous plastics. The findings are a warming sign that many other freshwater lakes may be similarly polluted, and that those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates, too.

    Water cascades down the spillway at Gross Reservoir a week after the floods tore through the area.

    The first night it started flooding, the caretakers, who live and work at Gross Reservoir climbed the hill and stayed awake most of the night, watching Advent Creek swarm their houses and office.

    They tried to sleep the second night, “but we were too busy watching that garage door — that was our gauge for the water level,” said caretaker Steve Bauman.

    When one of the worst storms in Colorado history submerged the Front Range in mid-September, it tore through the northern part of Denver Water’s collection system, forcing two treatment plants offline, reservoirs to swell and access roads to crumble in half.

    The storm bumped up water storage 6 percentage points, the largest September increase in our current supply system’s history, said Bob Peters, water resource…
