Preventing Water Pollution Starts in Your Backyard

Agricultural runoff is a prominent source of excess nutrients in water sources, but this nonpoint source of water pollution can originate with excess fertilizer being used on urban landscapes as well.

On April 13, 2017, the Colorado Foundation for Water Education was joined by Steve Lundt with the Barr Lake and Milton Reservoir Watershed Association for a webinar about cyanotoxins, algal blooms, public health and efforts to reduce nutrients in our water. 

“[BMPs] apply to your own lawn, just as they do on a corn field in Weld County,” says Lundt. “Don’t [fertilize] before a storm event and do soil testing—you may not even need phosphorus to grow your lawn.”

So, what can an urban lawn owner do when they want to grow a vibrant, healthy, lawn without contributing to nutrient pollution? The following blog post by American Turf & Tree Care discusses ways that people can reduce phosphorous pollution in Colorado’s water sources by ensuring that the way they care for their yard benefits not only their lawn, but also the environment.

There are a number of reasons why Denver and surrounding cities are among the fastest-growing metropolitan areas in the country, but certainly, one draw is the immense natural beauty of Colorado. Beautiful mountains and flowing streams make our area an outdoorsman’s paradise—tourists and Colorado residents alike flock to the area for hiking, camping and a chance to take in the scenery.

With the uncertainty that accompanies recent EPA spending cuts and policy changes, many people in the area rightfully have concerns regarding sustainability and important environmental regulations that protect these natural resources. In light of this, it becomes ever more important for businesses and individuals to make responsible decisions about actions that may impact the future health and beauty of our area.

Improper management of industrial waste, sewage and agricultural runoff are some of the worst offenders when it comes to pollution, but there are still a number of actions individuals can take to preserve Colorado’s water. Mindfulness, when it comes to the products you use in your backyard, can be a first step toward fighting pollution.

Phosphorus Pollution: Too Much of a Good Thing

Phosphorus is a natural ingredient found in soil that promotes root development and helps trees, shrubs and other plants mature and thrive. But if your lawn already has a sufficient level of phosphorus in the soil, fertilizer treatments can actually have a detrimental effect on the health of your grass and can lead to pollution.

Phosphorus works by attaching itself to soil particles, which are then absorbed by plants during their life cycle. When strong fertilizers are used in your lawn or garden, it can slow down the absorption process. In the meantime, heavy rains can wash phosphorus from your yard into ponds, streams, rivers and lakes nearby.

Phosphorus contamination can kill fish, cause algae to grow at alarming and dangerous rates, turn water green and lower water quality, leach into drinking water and eventually contribute to “dead zones” in the ocean. The good news is that this pollution is largely avoidable, as most excessive phosphorus present in the environment is washed into natural bodies of water as the direct result of human activities.

Regulation Is Only the First Step

The damage caused by phosphorus pollution is so severe that many states, Colorado included, have enacted laws to limit the use of phosphorus-heavy fertilizers. The Colorado Fertilizer Law, as enforced by the Colorado Department of Agriculture, regulates fertilizers and soil conditioners sold in Colorado for agricultural and residential use. The law requires that fertilizers be properly labeled with their tested nutrient levels – but these limitations only work if businesses and homeowners share a commitment to choosing fertilizers with low to no phosphorus.

“Pay attention to the three number label on the fertilizer you buy,” says Brad Woods, owner of American Turf & Tree Care in Greeley. The first number is nitrogen, the second is phosphorus, and the third is potassium. “You want to look for a bag where the second number is a zero or is low.”

How You Can Go Phosphorus-Free

You may not need additional phosphorus in your lawn. “Most lawn care providers offer complimentary soil testing and they can tell you what nutrients you need to restore balance to your lawn,” says Woods.

“One common mistake homeowners make is trying to fertilize dormant grass. When grass looks like it’s dying, but it’s just at the natural end of its growth cycle for the year, dumping fertilizer on top will actually do more harm than good,” says Woods. “If your soil is lacking phosphorus, a lawn care company can help you fix it in a way that is safe for your family and the environment.”

There are also some techniques you can use as part of your normal lawn maintenance routine to keep your yard naturally rich in phosphorus without the use of fertilizers, including:

    Composting: There is no better source of natural phosphorus than composted fruits and vegetables.

  • Tapping Organic Sources: If you need phosphorus and do not have access to compost, bone meal, manure, bat guano or soy meal will also do the trick! These materials are rich in nutrients and release phosphorus slowly, without the risk of contaminating water.
  • Mowing: When you mow your lawn in spring and summer, don’t bag the clippings! Grass clippings are high in phosphorus, and as long as they don’t mat the grass and block sunlight and oxygen from reaching your soil, they can be helpful in returning nutrients to the soil.
  • Don’t Overwater: Not only is overwatering bad for general lawn health, but it increases the risk of washing phosphorus out of your landscape.

Don’t wash the natural beauty of Colorado down the drain! Water pollution is far-reaching, and contamination can hurt local wildlife, impact the health of you and your family, and disrupt the environment at large.

Being conscientious about the products you or your lawn care team uses in your yard is a simple way to fight back against pollution and protect your local ecosystem.

Each year brings warnings of drought and with it, the implementation of water conservation measures. How do climatologists know if a lack of precipitation is a drought indicator or simply part of the earth’s natural cycle?

In a word: Data.

Pike's Peak Weather Station

Everything water related, including drought, begins with precipitation. Systematic weather reporting in Colorado began in the 1870s and 1880s, with the first weather reports coming from Pike’s Peak in 1873. In the late 1880s, the Colorado General Assembly passed legislation supporting the “Colorado State Weather Service” and in 1890, the U.S. Department of Agriculture took over climate monitoring and reporting. It was also in 1890 that the Cooperative Observers, a group of now more than 8,700 volunteers, began providing observational meteorological data in real time.

Today, precipitation in Colorado is tracked by a statewide network made up of the National Weather Service (NWS) and the Cooperative Observers. Together, they have set the standard for mapping and monitoring precipitation—recording the data that provides a history of precipitation across the state and thus sets a baseline for drought.

Currently, there are 200 to 250 weather stations in Colorado—some have operated continuously since the late 1800s. The longer a station has been compiling data, the better for revealing precipitation patterns and detecting abnormalities, which indicate something more serious. Still, a lack of data points across the state has kept climatologists from having a complete picture of Colorado’s precipitation.

Early on, data was not representative of mountain precipitation—a large part of Colorado—because gauges were primarily located in valleys, where the majority of people lived. With the help of the Natural Resources Conservation Service, data gaps were filled in the 1980s when they installed rain gauges in mountain forest clearings. Those mountain gauges improved coverage, but it was another 15 to 20 years before climatologists could establish a record that allowed them to truly understand Colorado’s climate.

With its vast size, it seems nearly impossible for there to be enough technology, information or data points to cover the entire state of Colorado. Tracking precipitation data has always been a time-consuming process. “When I started working here [Colorado Climate Center] in 1977, everything was done by hand,” says Nolan Doesken, Colorado State Climatologist with the Colorado Climate Center at Colorado State University (CSU). “Each week, we would receive the precipitation reports from around the state, add up the totals, plot them on a huge map, draw the contour maps and then write up a report.”

Surprisingly, this hands-on approach continued until 2000, when computers were finally used for precipitation mapping. However, the use of technology comes with its own set of issues. “Creating a map by hand was a more intimate process,” Doesken acknowledges. “You were more likely to question outliers in data. With a computer, people are less likely to question the results. They trust the computer.”

Regardless of technological improvements, including the addition of weather satellites, there have always been, and still are, limitations to what technology can achieve. Some areas are difficult to reach for installing rain gauges, others have low populations or populations of people who are not interested in reporting precipitation data—fewer rain gauges means fewer data points from which to gather information.

“Weather satellites only tell part of the story,” says Doesken. “Radar might show that precipitation is falling in a particular area because it is collecting information from 12,000 feet above a field; however, that rain is evaporating before it reaches the ground. We need data from the ground level to see the whole picture.”

The 1997 Fort Collins floods revealed that rain gauges were not showing the variability of rain and snow across the state; the heaviest rainfall leading up to the flood missed all of the official gauges, creating a situation where city officials were unaware of what was coming. This weather event resulted in the creation of The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) in 1998; a way to improve the quality of precipitation data, both locally and internationally.

CoCoRaHS is comprised of a community of volunteers 600px-Community_Collaborative_Rain,_Hail_and_Snow_Network_logo.svgdedicated to monitoring precipitation in their own, literal, backyards. After collecting precipitation data—rain, hail and snow—volunteers send their results to CoCoRaHS. Where there are more volunteers, there are more data points. Increased data points result in comprehensive data. CoCoRaHS volunteers cover gaps where there are no other weather stations and provide ground-level information that cannot be gathered by satellites.

Data collected by CoCoRaHS members during Colorado’s historic March 2003 blizzard proved to be invaluable. “Volunteers did a fantastic job of monitoring precipitation,” Doesken exclaims. “Without their data, we would not have known that there was a hole in the storm, just over Lyons, Colorado. The town was surrounded by areas receiving several feet of snow, while Lyons received only 2 to 3 inches. We never knew what we were missing before!”

As methods for precipitation data collection continued to improve, it became clear that past methods of determining drought were woefully inadequate. In the late 2000s, the National Oceanic and Atmospheric Administration’s (NOAA) National Integrated Drought Information System (NIDIS) came online and a clearer picture of drought emerged.

When the USDA started using NIDIS to determine if certain counties qualified for drought relief, Doesken and his coworkers were forced to acknowledge that their picture of drought was incomplete. “We discovered that our assessments of drought were crude,” Doesken says. “In reality, we probably don’t get drought depiction right. We realized that we needed to be doing a better job of depicting drought on a local level, particularly on the Eastern Plains.”


Photo Credit: USDA

They discovered that drought is far more locally dependent than they originally thought. For example, in Phillips County—a population of 4,356 and an area of 688 square miles—drought is reliant on something as simple as a farm’s location in the neighborhood. While one farm has plenty of water, the next farm over is experiencing a drought. Without data proving that the farmer is experiencing drought, grants and loans that provide drought relief will not be available to them.

Precipitation across Colorado has been monitored for more than 100 years. The data collected has helped climatologists determine the risk of drought which allows policymakers to plan for the future. While the system is imperfect, weather satellites and radar have improved, and on-the-ground data collection has increased. We are learning where there are breaks in coverage and knowledge, providing the opportunity for further improvements and a better understanding of how precipitation and drought impact our state.

Collecting precipitation data informs the way that we plan for the future. Keep an eye out for the upcoming summer 2017 issue of Headwaters Magazine, which will focus on how water data can impact policy decisions, public safety, water conservation and our own personal behavior.

Water Books from the Board of Trustees

The CFWE Board meets three times per year across Colorado

The CFWE Board meets three times per year across Colorado.  Here we are in Jan. 2014 at the Ralph Carr Justice Center in Denver.

CFWE is blessed to have a diverse and helpful Board of Trustees.  All 22 of them are committed to making CFWE the best water education organization in the state of Colorado, and I greatly appreciate their expertise and guidance.  Its not surprising that they, like our staff, are a bunch of “water geeks” who spend countless hours in their personal and professional lives thinking about our most important resource.

At each of our three yearly Board meetings, our Board Development Committee Chair, Chris Treese, does a round of introductions so we can learn a bit about each other.  At our January meeting, the question asked of each member was “What is your favorite water-related book?”  This was such a great list, I wanted to share it with our CFWE readers.  I hope you can find one or two titles here that will help get you through the remainder of a cold Colorado winter.  Do you have titles to add?  If so, please let us know!

The State of Colorado Coal

CFWE’s most recent Headwaters magazine on energy took a look at coal in Colorado.  Writer Josh Zaffos interviewed Jack Ihle, Xcel Energy’s director of environmental policy about the switch from coal to natural gas…

HW 32 coversmallEven with the rush toward natural gas, the push for renewables, and potential carbon emissions regulations, Ihle says Xcel—and Colorado—aren’t likely to fully divest from coal. Xcel is upgrading pollution controls at several coal plants to further limit smog and air pollution and keep the plants running and in compliance with Clean Air Act regulations. “We see value in balance even as certain drivers like emissions regulations will cause us to look harder at cleaner resources,” Ihle says. “Coal has been a very cost-effective resource and price-stable for a long time, and we’ll look for ways to make it as clean as we can.”

And the use of coal in Colorado isn’t the only thing changing.  So too is its mining.  High Country News recently published a great blog post discussing the future of coal mining in their backyard of Paonia.

“Coming out of the mountains is expensive,” says Bob Burnham, an independent Denver-based coal industry analyst. Mines in the Indiana Basin, which includes parts of Indiana, Kentucky and Illinois, are much closer to Southeastern power plants. Even Powder River Basin coal from Montana and Wyoming has an advantage over most Colorado mines: it doesn’t have to cross the Continental Divide.

As TVA cuts its coal consumption, it will cut especially deeply from its Colorado suppliers, says Mansfield. That’s especially bad news for Paonia, whose three local coal mines predominantly sell to TVA.

As we learned in writing about it, the switch from coal to natural gas is much more complicated than it might appear.  Get informed on this important topic and tell us what you think!

What I’m Reading: The Emerald Mile

Nicole Seltzer

Nicole Seltzer

As those close to me know, I am a poor student of history.  It’s not that I see no value in learning about the past (being “doomed to repeat it” and all) but most historical films or books don’t hold my attention.  And this just makes me feel guilty.  I am an educated woman of the 21st century–I am supposed to be enthralled by an esoteric tome on the history of all things.  Right? Well, to be straight with you, I’m generally not.

To compensate for my lack of interest, I often look for the “guilty pleasure” book that keeps me hooked but also teaches me a few things along the way.  For example, I made it through Ken Follet’s Century Trilogy over the summer, giving me some insight into World War I and II.  But even better is when I find a non-fiction book that combines adventure, history and things I care about like water and boats!  A tall order, you say?  Well, you clearly haven’t yet read The Emerald Mile, Kevin Fedarko’s history of the 1983 Colorado River flood and its impact on dam operators and river runners alike.

CFWE Executive Director Nicole Seltzer, braving Grand Canyon whitewater in 2012

CFWE Executive Director Nicole Seltzer, braving Grand Canyon whitewater in 2012

Here is a quick blurb from the jacket cover…

 IN THE WINTER OF 1983, the largest El Niño event on record—a chain of “superstorms” that swept in from the Pacific Ocean—battered the entire West. That spring, a massive snowmelt sent runoff racing down the Colorado River toward the Glen Canyon Dam, a 710-foot-high wall of concrete that sat at the head of the most iconic landscape feature in America, the Grand Canyon. As the water clawed toward the parapet of the dam, worried federal officials desperately scrambled to avoid a worst-case scenario: one of the most dramatic dam failures in history.

In the midst of this crisis, beneath the light of a full moon, a trio of river guides secretly launched a small, hand-built wooden boat, a dory named the Emerald Mile, into the Colorado just below the dam’s base and rocketed toward the dark chasm downstream, where the torrents of water released by the dam engineers had created a rock-walled maelstrom so powerful it shifted giant boulders and created bizarre hydraulic features never previously seen. The river was already choked with the wreckage of commercial rafting trips: injured passengers clung to the remnants of three-ton motorboats that had been turned upside down and torn to pieces. The chaos had claimed its first fatality, further launches were forbidden, and rangers were conducting the largest helicopter evacuation in the history of Grand Canyon National Park.

For anyone interested in Colorado River hydrology, the history of dam building in the West, the burgeoning environmental movement of the 1970’s, white water boating or the Grand Canyon, this book will have you hooked from page one.  It deftly weaves together stories about the history of commercial river running, the building and operation of Glen Canyon Dam, and the reckless yet poetic “speed run” during the height of the flood through the Grand Canyon.

But the thing I appreciated most was the author’s own musings on water in the west.  My favorite passage from the book is toward the end, as he tries to make sense of the dichotomy that exists at the base of Glen Canyon dam, which is also the start of the best wilderness adventure most people will ever have…

 “And together the canyon and the dam offer a far more meaningful reflection of the society that claims them both: its triumphs and its failures; what it has been willing to sacrifice and what it has chosen to preserve; the things it celebrates and those it mourns; the price it has willingly paid for progress and modernity, as well as the lessons that have been levied by those transactions. Perhaps nothing else speaks so succinctly and with such eloquence to who we are as a people— where we have come from, what we have gained and lost on our journey, and what we must eventually embrace to make ourselves whole.”

In reading the book, I felt a kinship with Mr. Fedarko (though I’ve never met him).  Partly for his obvious love of one of my favorite places on earth: the bottom of the Grand Canyon.  Mostly because he was able to aptly balance the stories of two completely opposite worlds.  This is what CFWE strives for every day, and it’s great to find others working in the same vein.  I was therefore excited to extend an invitation to Mr. Fedarko from CFWE and the One World One Water Center at Metropolitan State University to visit Denver and speak about the book.  Look for a date in January 2014, and in the meantime, pick up a copy of The Emerald Mile.  It’s a pleasure to read that you don’t need to feel guilty about.

Climate and Cattle

Cattle ranching in Jackson County

Cattle ranching (Photo credit: Wikipedia)

Drought can devastate Colorado’s agricultural industry, as we’ve seen this year in the Arkansas River Basin. An article pulled from this blog for the Grand Junction Free Press’ Water Lines column begins to highlight the impacts southeastern Colorado is seeing:

Area producers are seeing economic impacts — the 2013 winter wheat crop was almost nonexistent, corn planting for 2013 was less than 5 percent of average and there’s been at least an 80 percent loss of rangeland — projected crop loss for the region is more than $72 million. The impact is wide ranging and producers worry that they haven’t seen the end of it.

“From an agricultural standpoint this is a big area of the state and agriculture is the state’s number one economic area,” Finnessy said. Economics in the Arkansas Basin can impact the state’s economy as a whole.

Lost rangeland and high feed prices have caused cattle ranching to take a beating. Many ranchers in that part of the state are selling off their herds, from a Colorado Public Radio story aired yesterday:

John Campbell runs the auction. He says that because of the drought he’s auctioned off 3 times the normal amount of cattle this summer. And though that may be good for business today, he’s worried about the future.“When you sell off the factory, we won’t have the natural increase that those cows would generate for upcoming years,” said Campbell, who added some ranchers have totally liquidated their herds.

There’s worry that the cattle sell-off won’t have an impact just on Campbell’s auction, or the one across the street, but whole region’s economy – from the hotels to the banks to the restaurants. Continue reading

Celebrate Source Water During National Drinking Water Week



English: Drinking water fountain

Drinking water fountain (Photo credit: Wikipedia)


May 5-11 is National Drinking Water Week— as the EPA does their part to involve citizens and promote drinking water protection, consider source water in Colorado. As a headwaters state, we’re responsible for the water that nourishes 19 states and Mexico, plus we take pride in the quality of our water and the snow that falls to melt into water (isn’t that what the ‘Tap the Rockies’  campaign tapped into?).


As we wrote in the Winter 2013 issue of Headwaters Magazine,


Protecting the source of a water supply can be both personal and a matter of public health.

Source water protection work is in progress across Colorado, but looks different depending on the locale. Activities range from addressing nonpoint sources of pollution such as farm fertilizer runoff or contamination from roads, to reducing access to reservoirs or promoting forest health.

Grand Junction developed a watershed protection ordinance in 2007 after Genesis Gas and Oil acquired leases to drill within the Plateau Creek watershed on the Grand Mesa, a source of the city’s water. Residents were concerned about the potential impacts of drilling– particularly hydraulic fracturing– on their drinking water supply. To deal with these concerns, stakeholders including the cities of Grand Junction and Palisade, Genesis, federal land managers and local citizens came together, agreeing to a set of best management practices once drilling began. Genesis has avoided developing its leases within the watershed so far. In the meantime, Grand Junction is funding a water monitoring study to establish a baseline for the quality of its water.

Monitoring is something Colleen Williams, source water protection specialist with the Colorado Rural Water Association, frequently recommends to the water utilities she works with. By establishing a baseline for water quality, communities can track what is showing up in their water over time and watch for red flags. “It’s really important to have some way that they would know that there is a problem in that water source,” says Williams.

Some communities face concerns about oil and gas drilling, others with abandoned mine drainage or septic tank maintenance. Then there’s fire and drought– two of the biggest concerns, Williams says. Fortunately, much of Colorado doesn’t have contaminated water, she adds. A lot of the focus is on prevention– keeping water clean in the first place is far more cost-effective.

Williams also recommends public outreach and information sharing: “We want the community to encourage everyone to become a stakeholder, to become a steward of that drinking water source.”
