According to the study, published in the Proceedings of the National Academy of Sciences: "Water resources will become more difficult to predict in the Northern Hemispheres snow-dominated regions later this century due to the impacts of climate changeAs snow accumulation recedes and fails to generate reliable runoff, the amount and timing of water resources in areas such as the Rocky Mountains will increasingly depend on rainfall.". So in rough terms, 400,000 acre-feet is enough to meet the needs of over 2 million people, and probably even more. As far as future water supplies go, the outlook is not good. In an average year, the utility captures 94 billion gallons of water, enough to fill up nearly 157 Empower Fields at Mile High according to Denver Water. Our Design Standards page gives you everything you need at your fingertips. Lastly, we appended the output of the files into a format that we could use to correlate with our precipitation and reservoir water level data. The project is expected to save 13,000 acre-feet of water . Water development projects are typically decades in the making. Collection System Denver Water's collection system covers about 4,000 square miles. denverwater Water is everything, especially in Colorado and the West. Ensuring that our customers maximize water efficiency is a significant part of our long-term strategy. These factors are among the reasons Denver Water is planning to expand Gross Reservoir. On an average year, the utility captures 290,000 acre-feet of rain and snowmelt in its collection system. Having a large geographic area to capture water is critical because it provides redundancy in times of drought, emergencies, infrastructure maintenance and improvement projects, according to Elder. The stakes are high. If you have questions or if you want to verify or update your contact information with Denver Water, please call Denver Water Customer Care* at 303-893-2444 (7:30 a.m. - 5:30 p.m., Monday - Friday). This allowed us to view the polygons (reservoirs) on gridded axes. The CWCB is focused on helping prepare for and meet Colorado's future water supply needs. 2022 Denver Water. Denver Water said it expects to invest $2.3 billion over the next 10 years in projects that will maintain, repair, protect and upgrade the system and make it more resilient and flexible in the. Denver Water manages water supply and demand with careful research and analysis regarding streamflow, diversions, climate, customer demand and population estimates to ensure there will be an adequate supply of clean, reliable water well into the future. Today's customers benefit from a highly reliable water system, much of which was planned decades ago. Have questions about lead? All rights reserved. May 17, 2022. Follow the journey of water from snowflake to tap. By plotting the graphs we could see trends with the precipitation and reservoir storage. Once we got the codes to put everything in the correct projection, we were able to get a plot of the mosaic in hillshade. In order to determine the correlation between reservoir levels and precipitation we gathered data about the reservoirs primarily from Denver Water. We are upgrading and modernizing the northern portion of our water system. To map the watershed boundaries, we used ArcGIS Pro and tested it on the Dillon Reservoir watershed for the month of October in 2021 which mapped 426,754,575 cubic meters of snowfall volume. The boxplot below reveals that the total precipitation at these four reservoir locations has in fact decreased by decade. This reduction has occurred largely because of changes in the irrigation, thermoelectric, and industrial water use sectors. Meeting future water needs must be done in a manner that considers all solutions and addresses the varied water needs of Colorado and its citizens. We wanted to focus on four particular reservoirs, so we subset the data to feature the Antero, Dillon, Cheesman, and Gross reservoirs. Thats roughly 94 billion gallons of water or enough to fill up nearly 157 Empower Fields at Mile High. When it comes to Colorado and water, the only thing that seems to flow reliably these days is bad news. About 80% of Colorados snow and rain falls west of the Continental Divide. Though this was a breakthrough, the files were so big that they kept crashing our notebooks. Denver Water pays DPS rebates of $90 per toilet. All four reservoirs dropped far below their normal capacity when the monthly precipitation was less than normal and the reservoirs rebounded after a period of more rain. The four include Dillon Reservoir from the Western Slope Collection System which is tunneled through the continental divide, Gross Reservoir from the Moffat System in the north, and Cheesman Reservoir and Antero Reservoir from the South Platte Collection System. Denver Water has established drought severity indicators, response actions and program elements. Denver . In 2013, we entered into what was in essence a peace treaty with western Colorado, which resolved several issues and established a partnership. lakes, reservoirs, wide rivers, etc.). Environmental Data Science Seminar Series, Climate change will make Rocky Mountain water resources more volatile: study, Denver Water (Reservoir Elevation, Storage, & Precipitation Data), National Weather Service, National Operational Hydrologic Remote Sensing Center (Snowfall Analysis), U.S. Geological Survey, National Geospatial Technical Operations Center GAGES II, StreamStats, National Hydrography Dataset, National Map Downloader for DEMS (Reservoirs and Surrounding Location Data). Images: Courtesy of Stantec Last November, Denver Water, the largest water utility in Colorado, opened its new six-story, 186,000-sf administration building, located southeast of downtown Denver. Next, we graphed reservoir storage and precipitation together in one chart for each reservoir to look for correlation and decided to focus first on the decade from 2000-2010 since Denver Water told us about the drought starting in that time. But as population grows, pressure to move water from agriculture to cities increases. When we first accessed this data through Google Colab, there were thousands of polygons. Having a large and diverse collection system was critical to Denvers growth because the city lies in a semi-arid climate. About 91% of the state has at least severe drought and 28% of Colorado has exceptional. Denver Water is the water utility serving the City and County of Denver, Colorado and a member of Water Utility Climate Alliance. There simply wasnt enough moisture in the city to sustain the growing population, Elder said. Instead, we followed the same process with total annual precipitation, total snowfall, and average annual storage of each reservoir. Hearst Television participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our links to retailer sites. We completed an ANOVA (Analysis of Variance) test on the precipitation. Colorado's population, now 4.4 million, may reach 6.6 million in just 20 years. To what extent does dwindling supply from the Colorado River threaten the viability of western states? A mosaic of the four images was needed, this is where we combined all four images to create one large image that covered the area without any misrepresentation or scattered boundaries. Todays customers benefit from a highly reliable water system, much of which was planned decades ago. The Roberts Tunnel brings water from Dillon under the Continental Divide to the Front Range. An Oct. 12 decision by Denver's Board of Water Commissioners means the average Denver single-family residential water customer will pay $591 - up $35.51 per year or $2.96 per month. Being a steward of the environment is inherent in everything we do. July 18, 2022, 3:04 PM. The project is expected to save 13,000 acre-feet of water . With water in Dillon Reservoir out of reach until the tunnels maintenance project was finished, Denver Water had to rely on water coming down the South Platte River and from streams in Grand County. Gross Dam, built in the 1950s, was designed to be raised in the future when needed. Throughout this process within our timeframe we could not find sufficient data for Snow Water Equivalent (SWE) for all the watersheds. Eighty percent of Denver Water's supply passes through Strontia Springs Reservoir, an area prone to wildfires like the 1996 Buffalo Creek and 2002 Hayman fires that impacted the reservoir and operations. For each reservoir we were interested in their monthly average elevation in feet above sea level and storage in acre-feet. Initially we graphed both elevation and storage data for the reservoirs but determined that storage in acre-feet was a better measure of the reservoirs. Over the years the project became a model for how to negotiate new water storage projects, earning the support of major environmental groups, business leaders, water users on both sides of the Continental Divide and elected officials at the local, state and federal levels.

Eighty percent of Denver Waters supply passes through Strontia Springs Reservoir, an area prone to wildfires like the 1996 Buffalo Creek and 2002 Hayman fires that impacted the reservoir and operations. Lastly, a final limitation reveals that there are some gaps in data and a few incomplete data sets. Find daily updates on reservoir levels, streamflows and diversions, or check our Water Watch Report. Dillon is the largest reservoir in Denver Waters system. Denver Water's experts work tirelessly to provide clean drinking water to 1.5 million people in the Denver metro. The Colorado River's flow has declined by nearly 20% since 2000. Alternatives to high-water turf come in different forms but all lead to the same objective: using water differently, more efficiently, better. Hike the Gill Trail to catch scenic views of Cheesman Reservoir. Wise and thoughtful water supply planning is critical to ensure a secure future for the state. As a group we choose to look at reservoirs in the three different collection systems for Denver Water. Denver Water estimates that by that around 11,000 acre-feet of water from Grand County has not been collected, or roughly enough water to supply over 44,000 residences for one year. Find out what projects we're doing to improve our system. Colorado's climate is getting hotter and drier. Twelve entities joined forces for Water, Infrastructure and Supply Efficiency. State officials, after thoroughly reviewing the project and our related commitments, have determined it would result in a net improvement to water quality on both sides of the Continental Divide. The city of Denver and many surrounding suburbs in the metro area get their municipal water supply from Denver Water, a public utility company. From there we were able to load each image up individually. However, this was an inadequate representation of the elevation for the 4 reservoirs we were using in our project which were Dilon, Antero, Gross, and the Cheeseman. In 2019, the state of Colorado estimated the impacts of not meeting future water needs will ultimately cost the state between 355,000 and 587,000 jobs and reduce state and local tax revenue by between $3.4 billion and $6 billion. The increased storage in Gross Reservoir would allow more water to be stored in Denver Waters North Collection system provide additional redundancy in the utilitys ability to have a reliable water supply for customers. The first step with the data was to write code to plot the precipitation using matplotlib in Python and we graphed the precipitation from 1965 to 2022 at each reservoir location on the same graph. Get some answers. As a team, we recognize that there were some limitations to our research project. Get up to a $100 rebate on a WaterSense-labeled toilet.

It also is studying the possible water-system effects of climate changeand is working on a variety of future water supply projects, all to ensure that future customers will enjoy the same high-quality, reliable water system we have now. We relied heavily on a few sources for our data, and it would be even better to have more data from multiple sources. That time is now. Hike the Gill Trail to catch scenic views of Cheesman Reservoir. We then had to resample it into a smaller (400MB) tif file to reupload it and plot a hillshade out of it. Weve also committed to more than 60 different projects, creating new habitat and protecting rivers and streams on both sides of the Divide. Figure 1 is the watershed shapefile being plotted while figure 2 is the raster image that maps average snowfall accumulation in inches with each pixel representing an area of 1km by 1km. These gravel pit reservoirs store water for exchange purposes. The following maps break down the collection system and service area. Most of the reservoirs showed little to no correlation with r values between .3 and -.3 which essentially means there is not a correlation. Below is the code written for the precipitation graph. Every year its helpful to have a large and diverse water collection system, because you never know how much snow well see in Colorado and where it will fall, said Nathan Elder, water supply manager at Denver Water. Additionally, developing this water supply will support the state's water plan and Colorado River Basin Implementation Plan by helping to meet future water needs for both the East and West Slope.

Studying this would contribute to determining the potential impacts of a future water shortage on certain demographics. Having a plethora of data files to work with, we created a looping function to download the snow cover raster data automatically. Denver Waters collection system is centered on the states mountains and foothills, because thats where most of Colorados precipitation falls. ANOVA (Analysis of Variance) is a statistical test to see if groups of the same variable are statistically different. How does decreasing precipitation and declining snowpack due to climate change across the mountain regions affect the Denver water supply? Image credit: Denver Water. But year after year, water levels. Denver Water is a leader in incorporating climate change into the planning process. Denver Waters 4,000-square-mile collection area supports 1.5 million people across the metro area.

Customer Care may be experiencing long wait times. This year, for example, Nebraska's governor caused jaws to drop when he announced a plan to divert water out of Colorado into his state. The features in this dataset represent areal bodies of water (i.e. Denver Waters storage capacity is imbalanced, with 90% of its storage capacity located in its South System and the remaining 10% located in its North System. A new study from Colorado State University researchers shows that about 80% of the water running through Denver's inviting stream parks late in the summer flows there from lawns drenched in Denver tap water and leaks from the agency's intricate system, not from snow runoff or foothills rain. There are rules to watering your Denver lawn this summer, and they began May 1 The rest of those supplies are in the South Platte River Basin, where there's no drought at all. Unfortunately while figuring all this out all at once. We also had to ensure that the previous data files inches and volumes values werent getting added to the output of the succeeding data file. This relationship is represented by snow coverage data and reservoir levels. In this undated handout provided by Stephen Heidt for the gubernatorial campaign, shows Democratic gubernatorial candidate Stephen Heidt challenging incumbent Republican Governor Brad Little in the November 8, 2022 election. Because most of the water comes from mountain snowmelt in the spring, water is stored in mountain reservoirs until it is needed. Our Design Standards page gives you everything you need at your fingertips. But similar drought stresses and the effects of a hotter climate are changing the South Platte River and other basins in . Today, agriculture accounts for approximately 86 percent of all surface and groundwater use in the state. Denver Waters collection system covers about 4,000 square miles. Get up to a $100 rebate on a WaterSense-labeled toilet. Denver Water sources its water mainly from Western Colorado (the part of Colorado west of the Continental Divide) as snowfall and precipitation are much greater there (representing 80% of Colorados total annual precipitation). The new dual lift pump station and reservoir is located at 64th Avenue and Picadilly Road. Save your business water and money with Denver Waters rebates. See the figure titled Average Daily Precipitation by Month (1965 to 2022) for reference. There are comments in the code snippet below showing what is going on with each function. Climate change has greatly impacted the water supply to Denver Water in a multitude of ways including reduced annual precipitation rates (most notably snowfall), and an increased loss of water stored in reservoirs caused by evaporation. Elder says. Additionally the data came from a decades long data collection process with changing methods of collection, which means there could be some variability in the data. This would give us a more complete picture of the state of water resources for the Front Range. Denver Water serves 1.4 million people in the City and County of Denver, Colorado, and a portion of its surrounding suburbs. The results were inconclusive and resulted in a pretty low r value which means there was relatively little correlation when looking at the data by month. We communicated with several representatives from the public utility to request data for reservoirs that are representative of the different collection systems. The new layers with the shapefiles of the reservoirs and their watersheds were created and were added to the map. Correlation between Snowfall, Precipitation and Reservoir Levels in the Denver Water Supply, Aaron Doherty: Advanced Intern, Geospatial Sciences, Dr. David Parr: Instructor of Geographic Information Sciences at MSU Denver. It is important to note that Antero is a drought storage reservoir so it typically remains full except in times of drought when the city needs to tap into its resources. Gross Reservoir, located in the foothills above Boulder, Colorado, is one of Denver Water's largest reservoirs with a capacity of 41,811 acre-feet of water. There is annual fluctuation in how full the reservoirs with the spring to summer snowpack melt out and precipitation. WSP is one of the world's leading engineering professional services firms, with 37,000 talented people, based in more than 500 offices, across 40 countries. Suburban customers living outside of the city will see an average increase of $47.26 annually, or $3.94 per month, and will pay an estimated $788 per year.

Using historical data sourced from our meetings with Denver Water, we are looking to prove a correlation between snowfall amounts and available water supply. 1:36. Instead we looked at snowfall and precipitation compared to storage. DENVER (CBS4) - The weekly drought monitor released Thursday morning offered no good news for Colorado. Another of Denver Waters important water-carrying tunnels, the Moffat Tunnel, will be closed for maintenance in 2021, which means Denver Water wont be able to access to water from Grand County during that project. We are committed to being a good neighbor during construction projects. See our. Each graph follows the same scale with 100% being the maximum storage capacity for each reservoir. The Daily Sun-Up. Treat your curiosity about water quality to a virtual tour of our potable treatment process. This system is suitable for washing large fleets in short amount of time and lesser investments. The lower lift meets the hydraulic grade line of the new airport, while the high lift supplies adjacent areas. Then we put the data together for yearly storage averages and total annual precipitation and snowfall and from there saw that Cheesman had an r value of .588 and shows strong correlation between storage and precipitation. In addition we totaled the precipitation in inches by month and year for different comparisons. 2022 Denver Water. The future of our community isn't something we sit back and wait for longingly. This relationship is represented by snow coverage data and reservoir levels. Denver Water's experts work tirelessly to provide clean drinking water to 1.5 million people in the Denver metro. Get some answers. The process we used was to read in the .csv files from Google Collab and set them to a variable called reservoir_data_date for each reservoir. To the right is the final master map with the lines representing the four images that needed to be mosaiced (but this image is the mosaic; the lines are just a representation of where the images were separated at first) that represents all these attributes that tie our data together visually. All rights reserved. All rights reserved. As one of the primary organizations controlling water distribution of Colorado's allocation of Colorado River water, Denver Water determines where "their" water goes and how it is used. After doing so we noticed a major change in precipitation amounts at the reservoirs in the mid-1990s. Wildfires are another big concern for the utility. Denver Water's Plan Infrastructure Renewal More than 3,000 miles of pipe 325 miles of pipe built 1880-1920 Annually replace about 30,000 feet of pipe and rehabilitate another 30,000 feet At this rate, it would take 200 years to replace or rehab all pipe. Denver Water, the state's oldest and largest water utility, was established in 1918 to ensure a stable water supply for the growing metropolis. In continuing with those efforts, Denver Water has embarked on a new Integrated Resource Plan, which will help guide decisions related to our water system over the next 50 years. In fall 2021, exploratory drilling will occur in Congress Park. Our experts work 24/7 to deliver clean, safe, reliable water to 1.5 million people including you and your family. Overview. The sourcing of water mainly from snowmelt necessitates the use of reservoirs to store water to be available for municipal use year-round. We are upgrading and modernizing the northern portion of our water system. The Future of Colorado Water: Living with Limitations. Due to time constraints, we decided to plot the rest of the master map in ArcGisPro because adding more layers to the map would take far less time and create a more accurate visual representation for the research. Accomplishing this was a tedious task in python but we started with downloading the raster DEM - satellite images that are taken to represent elevation, streams and rivers in a given area- from the USGS website through national map. 2022 Denver Water. Nov 2, 2022 Updated Nov 3, 2022. One program instituted to address this more efficient water use is Slow the Flow, an irrigation audit service that enhances the beauty of your lawn, while reducing your water use by up to 60%. Denver Water takes its water source mainly from the Colorado River and provides water to about 25% of the state of Colorado's population. These factors are among the reasons Denver Water is planning to expand Gross Reservoir. Below is the initial part of the notebook where we started using code to create the mosaic image: After we got the mosaic plotted and imported, things started to get complicated because the file was almost 2GB and was made as an array image not a tif. Established in 1918, the utility is a public agency funded by water rates and new tap fees, not taxes. Our research yielded inconclusive results when calculating correlation between reservoir storage and snowfall and liquid precipitation for the Antero, Cheesman, Dillon, and Gross reservoirs. Facts and factors about the demand for water. The builders of the Denver Water collection system had to look to the mountains to ensure a reliable supply of water. Due to the format of the URL for each data file, we had to make sure that our looping function addressed this so that it downloaded each subsequent file without failing, which happened a couple of times. Have questions about lead? Denver Water moves water from western Colorado into eastern Colorado, and as with Northern and Southern California, that importation of water creates tension between regions. We're in the very beginning stages of research and planning for this area. The additional storage also will better balance the north and south sides of our water system, allowing us to be more flexible in reacting to emergencies, like wildfires, and more frequent and extreme weather patterns due to climate change. After subsetting the data, we plotted each body of water individually using matplotlib.pyplot. Over the years, additional dams and tunnels were built to capture and store more water for Denvers growing population. In the future, we would be interested in duplicating the workflow for all the reservoirs that supply Denver Water to look for trends and expand the research to all the reservoirs that supply water for the utility companies in the Denver Metro or even the entire Front Range. Hike the Gill Trail to catch scenic views of Cheesman Reservoir. Were working through the final stages of the legal process before beginning construction. We are upgrading and modernizing the northern portion of our water system. The reservoir precipitation data have a p-value < 0.01, indicating that the groups of the variable are, in fact, statistically different. The reduced water use also is attributed to. On a per capita basis, aggregate water withdrawal in the United States has been dropping since at least 1985. Furthermore, an important area for further research is the social impact of droughts and lower reservoir levels. We sourced data from the National Operational Hydrologic Remote Sensing Center which has daily, monthly, and seasonal raster .tif files of snowfall accumulation that goes back to 2008. Closing the tunnel meant no water could be brought to customers from Dillon Reservoir in Summit County. Our Integrated Resource Plan will guide decisions related to our system for the next 50 years. We used a dataset that was created and published by the Colorado Department of Transportation (CDOT), however we accessed it via the University of Colorado Boulders GeoLibrary online. In continuing with those efforts, Denver Water has embarked on a new Integrated Resource Plan, which will help guide decisions related to our water system over the next 50 years. As a point of reference, the water project that serves the Denver metro area serves about 1.3 million customers, and their annual use is about 250,000 acre-feet. The Colorado River is the source of about half of Denver's water supply. Research focuses on four reservoirs that supply water to Denver Water: Antero, Dillion, Cheseman, and Gross. Long-term planning always hasbeen a key element in Denver Water's ability to meet customers needs in a rapidly growing, semi-arid region. Despite the reductions in per-capita water withdrawal, total U.S. withdrawal rose from 1985 to 2000, largely in . With a growing population in the Denver metro area, coupled with the effects of climate change on the region, a multitude of issues have presented themselves in sourcing water for a growing region, that year after year is becoming more prone to drought. Denver Water has raised the funds to provide its share of the match through a small surcharge added to customers' water bills. Municipalities in southern metropolitan Denver pump their main supplies from non-renewable aquifers and in the San Luis Valley, many agricultural wells have been shut down in order to sustain the local aquifer. The Antero graph is plotted with a dashed line style since it is a drought storage reservoir and therefore functions a little differently than the other three reservoirs. Labels and cartographic details were added to make sure the specifics were highlighted such as the cities, elevation, and size of each watershed. . Susan Stanley, of Boulder, and her dog, Wile E. Stanley, paddle board on Gross Reservoir outside above Boulder. State officials approved the project in 2016. As part of the program, $20 million was recently granted to El Paso's water board to help construct a direct potable reuse facility. The goal was to find snowfall data that we could use to calculate the amount of snowfall volume for each reservoir. Plans and partnerships to protect our water supply at the source. Sign up to receive TAP's top headlines every week. through 42-in. The new system includes 360,975 ft (68.4 miles) of pipe ranging in size from 8-in.

This observation led us to calculate correlation between precipitation specifically and reservoir storage. The utility estimates that it will only cost each household a total of $27 over the five-year period to fund the program and reduce future water treatment costs. The water flows down rivers and streams, then through a network of tunnels, pipelines and canals to treatment facilities in the Front Range to be cleaned for delivery to homes and businesses. What are the threats and challenges to existing and future water uses? Find out what projects we're doing to improve our system. One example of the need for diverse sources of water occurred in 2020, when Denver Water had to close the Roberts Tunnel for maintenance. That's enough water to supply 1.06 million homes or to irrigate more than a half-million acres of crops. Denver Water manages water supply and demand with careful research and analysis regarding streamflow, diversions, climate, customer demand and population estimates to ensure there will be an adequate supply of clean, reliable water well into the future. Save your business water and money with Denver Waters rebates. we discovered that the files werent plotting in the correct projection because we were lacking certain rows and columns that placed them correctly on the map. Have questions about lead? After seeing the data visually with the graphs we calculated the correlation between storage and precipitation by monthly averages. The Moffat Tunnel carries water, collected from 36 Grand County streams, and funnels it under the Continental Divide to be stored in Gross Reservoir before going to treatment plants in the metro area. Today. |Notice of Nondiscrimination|Privacy Policy. The Gross Reservoir Expansion Project will allow us to capture extra water when its available to help us avoid shortages during droughts. DPS officials said they'll also sell old brass parts, $2 a pound, to help finance the switch. Accurate visual representation was necessary to tie in the correlations between snow pack, precipitation, and elevation data. The Colorado Rocky Mountain range is viewed at 33,000 feet on May 19, 2022, near Denver, Colorado. ASR may contribute to our customers' drinking water supply in the future.

In 2002, the Denver area experienced simultaneous natural disasters from drought to wildfire and then rainstorms and this had serious impact on the supply of water in their largest water reservoir . Were building a new state-of-the-art treatment plant, replacing old delivery pipes, reusing water, implementing efficiency practices, and one of our most critical projects working to expand Gross Reservoir on federal lands in Boulder County. denverwater Water is everything, especially in Colorado and the West. What areas would suffer the most when reservoir levels are low? These shapefiles were overlaid on top of the DEM mosaic image in order to better understand how the precipitation and snowfall that the bodies of water received might be impacted by their elevation. article. The bold outline is the state of Colorado boundary to give a comparison as to how big the mosaic image really was. Our Design Standards page gives you everything you need at your fingertips. In times of drought, if the South Platte River Basin is experiencing dry conditions but collection areas on the West Slope are experiencing normal or above average precipitation, Denver Water is able to draw water from rivers and streams on the west side of the Continental Divide.
