Change Brings Hope

In October 2016, The Durango Herald carried a modest story sporting the headline, Trout Discovered in Creek Long Devoid of Fish.  In the southwest corner of Colorado, where abandoned mines and contaminated streams have long been a part of the otherwise magnificent mountain landscape, this is encouraging news—especially for a community that, just two years ago, saw the Animas run yellow.

The San Antonio Mine complex, north of Silverton, Colorado, has been a fixture on the flanks of Red Mountain Pass for over 100 years. While most active mining ceased in the 1940s, the spoil piles and orange drainage from the Kohler Tunnel remained, contaminating streams with high concentrations of copper, lead, cadmium and zinc, and eliminating the fishery resource in Mineral Creek.

In the late 1990s and early 2000s, several entities joined together with the hopes of improving water quality and restoring the natural function of the watershed. The Animas River Stakeholders Group, whose mission is to improve water quality and aquatic habitat in the Animas Watershed, determined that drainage from the Kohler Tunnel contributed the largest amounts of metals to the upper Animas Watershed. As a result, the stakeholders group designated the tunnel drainage as its highest priority for remediation.

Hydrogeological studies and other research conducted by the stakeholders group identified the Carbon Lake Ditch as the likely source of water seeping into the mine and the Kohler Tunnel, impacting water quality. The 50-year-old irrigation ditch diverts from the upper Mineral Creek Basin and winds its way across the mine complex to deliver water to the other side of Red Mountain Pass. Winter ice buildup in the ditch and heavy summer rains caused occasional breaches, resulting in erosion and surges of mine drainage from the tunnel. The obvious solution was to eliminate the source of water infiltrating the mine, so the stakeholders group targeted their efforts on the ditch.

With a grant from the U.S. Environmental Protection Agency, the Animas River Stakeholders Group purchased the entire 15 cubic feet per second (cfs) Carbon Lake Ditch water right from the owners who were willing to part with their water right in favor of reliable, local water supplies. The stakeholders group removed the physical structures from the streams, completed ecological restoration of the ditch and plugged the Kohler Tunnel to prevent future drainage into the stream.

Discontinuing diversions and removing the headgate did not guarantee that the restored flows would stay in Mineral Creek to benefit the environment—legally, that water would be free for other uses under Colorado’s prior appropriation system. The next challenge was to find a way to protect those restored flows. The Animas River Stakeholders Group and project partner the San Juan Resources Conservation and Development Council reached out to the Southwestern Water Conservation District and a local law firm where the attorney consulted was a former Colorado Water Conservation Board (CWCB) member with a wealth of knowledge about Colorado’s Instream Flow Program.

Colorado’s Instream Flow (ISF) Program was the linchpin in the stakeholders group’s success. In the early 1970s, the Colorado Legislature pioneered protections for the water-dependent natural environment by creating the ISF Program.  An instream flow is a statutorily recognized type of water right that protects a natural stream from an upstream point to a downstream point. These water rights are administered like any other water right in the state, with a priority date confirmed by water court decree. At the time, the program provided the CWCB with the exclusive authority to appropriate or acquire water for instream flows to preserve the natural environment.

The CWCB can appropriate new junior instream flow water rights or acquire senior water from willing water rights owners for instream flow use. Under this acquisition authority, once an agreement is reached with the willing owner, the CWCB changes the water right through the water court change process to instream flow use. The water right is then legally protectable in the river with its original priority date. It is CWCB’s acquisition authority that the stakeholders group sought to secure instream flow protections for the newly-purchased Carbon Lake Ditch water right.

In March 2001, the Animas River Stakeholders Group and the San Juan Resource Conservation and Development Council presented the CWCB with an offer to donate the Carbon Lake Ditch water right to the Instream Flow Program to protect restored flows in Mineral Creek and two tributaries. However, in the course of conducting routine investigations, CWCB staff identified a significant program limitation. The original statutes passed in 1973 placed sideboards on the CWCB’s authority, limiting water appropriations and acquisitions to the minimum amounts required to preserve the natural environment. In the case of Mineral Creek, the amounts required to preserve the environment were determined to be between 2.5 and 6.6 cfs.  Yet, the Carbon Lake Ditch water right was decreed for 15 cfs, and under the existing law, there was no way to protect all of the restored water with an instream flow right.

CaptureAs highlighted in CFWE’s spring 2004 Headwaters Magazine issue, “Changing Times, Changing Uses”, societal values change. In 2002, the legislature passed Senate Bill 156, allowing CWCB to acquire water rights to preserve and to improve the natural environment. This amendment, the first significant change to the Instream Flow Program in more than 30 years, broadened the CWCB’s authority and created statewide opportunities to restore streamflow to dewatered streams and to improve existing environmental conditions. After the bill was signed into law, the CWCB clarified the water right donation and changed the full 15 cfs of the Carbon Lake Ditch water right for instream flow use to preserve and improve the natural environment. Roughly 15 years after the legislative change and the CWCB’s acquisition of the Carbon Lake Ditch water right for instream flow use, we see tangible results.

“This is the first time in recorded history of a report of fish existing in the headwaters of Mineral Creek,” said Bill Simon, retired coordinator for the stakeholders group, in the 2016 Durango Herald article. “We are a bit surprised by the great results so soon after remediation.”

The presence of a resident brook trout population with diverse age ranges is indicative of the dramatic improvement in water quality within the reach where flows were restored and are now protected by the CWCB’s instream flow right. The Durango Herald reports an amazing 70 percent reduction in zinc and copper, and a 50 percent reduction in cadmium in Mineral Creek since completion of remediation and flow restoration.

“We knew that water quality in the upper part of Mineral Creek had dramatically improved,” said Peter Butler, Animas River Stakeholders Group coordinator, “but we didn’t expect it to support trout.”

The fantastic success story for Mineral Creek and the stakeholders group is a testament to the possibilities when local communities, state agencies and the legislature work together to solve problems. With CWCB’s ability to acquire water to improve the natural environment, this is a success story for the entire state of Colorado. The benefits achieved in Mineral Creek can, over time, be realized on many other streams, too.

Colorado’s ISF Program, now in its 45th year, operates statewide and the acquisition tool is available to any water right owner interested in donating, leasing or selling all, or a portion of, their water to preserve or improve the natural environment. The Colorado Water Trust, a nonprofit created in 2001 to restore flows to streams and rivers in need, works closely with the CWCB and can help facilitate temporary and permanent water transactions throughout the state.

Learn more about how to use water to benefit the natural environment by visiting the Colorado Water Trust and Colorado’s Instream Flow Program websites.

The Colorado Water Trust is a non-profit organization created in 2001 to restore flows to Colorado’s rivers in need.  The Water Trust uses voluntary, market-based tools to develop projects with water right owners to help keep Colorado’s rivers flowing. The Water Trust works closely with the Colorado Water Conservation Board and the state’s Instream Flow Program to ensure flows are protected.

The Runoff Conundrum

When a summer storm crosses the eastern plains, drowning farmlands in a deluge, more than water ends up flowing into Colorado’s rivers, lakes and streams.

On April 13, 2017, the Colorado Foundation for Water Education was joined by Troy Bauder, with Colorado State University Extension, for a webinar in which part of the discussion centered on nonpoint source pollution. Bauder focuses on working with agricultural producers to reduce nutrient losses on their fields.

Runoff, a nonpoint source, occurs when there is more water than the soil can absorb. Agricultural runoff carries a bit of everything it touches—excess fertilizer, animal waste, soil and more. Water that is not absorbed into the ground moves across the land, picking up whatever it can carry, and drains into surface water and groundwater sources.

“Ag nutrients—nitrogen (N) and phosphorus (P)—are absolutely required for productive agriculture,” Bauder says. “Of course, we need good management to prevent the accumulation of too much N and P in our soils and to reduce the potential for movement to surface and ground water.”

When nitrogen and phosphorus—two nutrients found in agricultural runoff—are deposited in excess in water bodies, it leads to algal blooms, reduced dissolved oxygen content, which is harmful to aquatic plants and animals, and can compromise drinking water supplies.

If rain falls on 30 farms, with 20 of them using fertilizers to supplement nutrients in the soil, and the excess of these nutrients finds its way into the runoff, who is to blame for compromising water quality? Who is responsible for nutrient pollution? Since no one farm can be blamed for the degradation of water quality, agricultural runoff is a challenging nonpoint source pollutant to manage and regulate.

Colorado’s Regulation 85, a nutrient policy passed in 2012, regulates point sources of nitrogen, phosphorous and chlorophyll a in surface water, setting discharge limits and requiring monitoring; however, Regulation 85 currently allows for a voluntary, incentivized, approach for reducing nutrient pollution that originates in nonpoint source pollution.

“We’ve partnered with CDPHE [the Colorado Department of Public Health and Environment] to produce some resources and an outreach program called Colorado AG Water Quality,” Bauder continues. “The purpose of this outreach effort is to get the word out to growers about how Reg. 85 could potentially affect them.”

Taking ownership of nutrient pollution and implementing best management practices gives agriculture the opportunity to avoid stringent state regulations. In 2022, the current, voluntary, approach will be evaluated to determine if progress has been made with the implementation and adoption of best management practices (BMP) as they relate to nonpoint source pollution, agriculture and water quality. Additional regulations may be considered depending on the results.

Reducing nutrient pollution is achieved through the implementation of BMPs, including improvements in fertilizer management, conservation tillage, irrigation, manure handling and soil erosion. The adoption of BMPs by Colorado agricultural producers benefits agriculture, as well as water quality. When implemented successfully, not only will there be a reduction in nutrient pollution, but it will reduce the need for future regulation.

“We want to work with our growers on the agronomic and economic feasibility of these practices to help them understand how they can help their bottom line,” Bauder says.

BMP effectiveness depends on what is known as the 4 R’s: Growers need to use the right amount (rate), right placement, right timing and right source. Combined with improved irrigation management, these BMPs improve the efficacy of the nutrients and prevent the potential for movement, which often results in nonpoint source pollution. Irrigation management can include altering the method by which water is delivered with system upgrades, combined with scheduling watering at the right time of day and in the proper amounts to reduce runoff. Ultimately, implementing these BMPs will benefit the grower’s bottom line while simultaneously protecting water sources from being impacted by nutrients.

“It’s definitely important to engage growers early and often in the process,” Bauder concludes. “Not only the growers, but their representatives, commodity groups and the people who advise them.”

While nutrients are certainly necessary for successful and sustainable agriculture, the execution of BMPs will help mitigate nutrient loss and movement, and in turn, reduce nonpoint source pollution due to runoff. Providing incentives, tools and resources to growers is critical to BMP implementation and success, as well as keeping Colorado’s water sources clean and reducing the impact of nutrient pollution.

In Bloom

Ferril Lake Without Algae                  Photo Credit: Rolf Krahl

Ferril Lake in Denver’s City Park is a favorite summer stop for those looking to relax in the sun or take a trip around the lake in a paddle boat. Last summer, a perfect storm of heat and increased nitrogen from goose droppings allowed algal blooms to thrive. Blooms of up to 10 feet thick sprung from the lake’s bottom and, at one point, coated nearly ninety percent of the surface—sidelining paddle boats, releasing a foul stench, destroying the aesthetics of the lake and causing additional ecological issues below the surface.

The presence of blue-green algae, known as cyanobacteria, in Ferril Lake is not uncommon. An increase in nutrients—nitrates and phosphates—along with increasingly warm temperatures, encourage the growth of cyanobacteria in lakes, streams, ponds and other surface waters. For years, the city of Denver has been looking for solutions to the now annual, and growing, issue.

In the case of Ferril Lake, the algal bloom is a result of non-point pollution sources—urban runoff (grease, oil and chemicals) from Denver’s streets and the aforementioned goose droppings. Other non-point pollution sources include the excess use of fertilizers, herbicides and insecticides from large-scale agriculture, as well as home gardens, energy production and sediment.

The presence and exponential growth of algae blooms in water sources deplete the water of dissolved oxygen, killing aquatic plant and animal life that depend on specific oxygen levels for survival. Without an increase in oxygen through treatments or during seasonal turnovers, lakes overrun with algae blooms will eventually “die,” unable to support life again.

In certain conditions, the cyanobacteria will also produce cyanotoxins, which are harmful to the environment, animals and humans, whether through direct contact, inhalation and/or ingestion. Human symptoms range from headaches, stomach cramps and allergic reactions to more severe cases of seizures and respiratory arrest. In the most extreme cases, contact with cyanotoxins can also lead to death. Coloradans in rural and urban areas are working together to monitor and address these threats to our water quality and public health.

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.”

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.

World Water Day 2017: Why Waste Water?

Today is World Water Day 2017!wold waterday

In 1993, March 22 was designated as World Water Day by the United Nations (U.N.), thus setting aside a day for the world to focus its attention on finding solutions to the world water crisis.

Currently, 1.8 billion people around the world do not have access to safe drinking water, resulting in nearly 1 million annual deaths. Launched in 2015, the U.N. Sustainable Development Goals to Transform the World include the goal of all people having access to safe drinking water and sanitation by 2030.

 

World Water Day is a great day to concentrate on making that goal a reality!

The emphasis of this year’s campaign is wastewater—the water that runs down the drain after washing your hands or out into the street when you water your lawn. Wastewater from our homes, cities, industry and agriculture, most often finds its way back into the ecosystem untreated, contributing to pollution, and without being reused, wasting a limited resource.

Wastewater Treatment Stages

There are ways to treat and reuse wastewater responsibly and safely in order to return it to the environment. In doing so, water can be stretched to its maximum potential.

Why waste water when it has so much left to give? To learn more about wastewater and its place in the water cycle, check out the  2017 Fact Sheet.

Water DropWorld Water Day is a day to educate ourselves on what we can do today, and throughout the year, to secure our collective water future—making water work for everyone. You can join the global conversation and share your water story using the hashtag #MyWaterStory.

Together, we can make a difference when we protect our most precious resource—WATER!

Opinion: Bill Promotes Opportunities for Implementing More Aquifer Recharge and Recovery Projects in Colorado

By Ralf Topper

HB 17-1076 is currently making its way through the legislative process having passed the House and the Senate.  This legislation, concerning rulemaking for artificial recharge of nontributary aquifers, opens the door for opportunities to implement aquifer storage and recovery programs in nontributary aquifers outside of the Denver Basin.  Nontributary groundwater, as defined in Colorado Revised Statute 37-90-103 (10.5), is groundwater whose connection to any surface stream is so insignificant that it is considered isolated from the surface water for water rights administration purposes.

HB 17-1076 is a first step in creating some administrative certainty and legal framework for districts in other parts of the state to consider implementing aquifer recharge and recovery projects to meet their water management objectives, and should be endorsed by the water community.  The bill’s use of the term “artificial recharge” is unfortunate, as the use of that term is dated in scientific and engineering literature though still used in reference to older studies and legislation herein.  Aquifer storage and recovery (ASR) is designed to introduce water into and store water in underlying aquifers with a future extraction component when additional supplies are needed.  ASR is typically implemented through wells.

Increasing storage is an integral theme of Colorado’s Water Plan, published in 2015, and aquifer storage and recovery opportunities dominate the plan’s discussion regarding groundwater.  Subsurface water storage in aquifers can significantly reduce the financial, permitting, environmental, security, and socioeconomic hurdles associated with construction of new surface-water reservoirs.

In 1995, the State Engineer promulgated rules and regulations for the permitting and use of waters artificially recharged into the Denver Basin aquifers.  The Denver Basin is the only aquifer system in Colorado with specific rules regulating the recharge and extraction of non-native water for storage purposes and as such is currently the only area in Colorado with active ASR projects.  The promulgation of those rules has provided both opportunity and certainty for water districts to implement subsurface water storage projects.

  • Centennial Water and Sanitation District started ASR operations in 1994 and currently has 25 wells permitted and equipped to inject water into Denver, Arapahoe, and Laramie-Fox Hills aquifers. Through 2014, they have stored over 14,000 acre-feet of potable water.
  • Others districts that have implemented ASR operations include Consolidated Mutual, Colorado Springs Utilities, and Castle Pines Metropolitan.
  • East Cherry Creek is currently in the testing phase and implementation plans are moving forward in Castle Rock, Meridian, Rangeview, Inverness, and Cottonwood.
  • Denver Water has initiated a significant evaluation program and South Metro Water Supply Authority considers ASR a critical component of utilizing water supplies from the WISE partnership.

Subsurface water storage opportunities in bedrock aquifers in other portions of Colorado have been well documented.  In 2003, the Colorado Geological Survey produced a statewide assessment of subsurface storage potential opportunities for then-director of Colorado’s Department of Natural Resources Greg Walcher.  Published as Environmental Geology Series 13, that study identified 29 priority regional consolidated bedrock aquifers with potential storage capacities from 10’s of thousands to over a million acre-feet.  In 2006, Senate Bill 06-193 directed the Colorado Water Conservation Board to conduct an underground water storage study in the South Platte and Arkansas River basins.  That study  identified a number of areas for potential underground water storage in both basins with available storage capacities of tens to hundreds of thousands of acre-feet in most areas.

 Ralf Topper has recently retired with 16 years of service as the senior hydrogeologist in both the Colorado Division of Water Resources and the Colorado Geological Survey.  He has earned advanced degrees in Geology (BS, MS) and Hydrogeology (MS) from CU-Boulder and Colorado School of Mines, and has over 35 years of professional geoscience experience in both the private and public sectors.  He is a Certified Professional Geologist, a Geological Society of America Fellow, and an active member of both national and state groundwater societies.  Ralf has authored numerous papers and publications on Colorado’s groundwater resources including the award-winning Ground Water Atlas of Colorado.
