Ben Harding, AMEC Earth and Environmental: “Impact of Projected Climate on Stream flows in Colorado”

Mr. Harding's Presentation

Ben Harding has more than 35 years' diverse experience in water quality and water resources engineering.  Mr. Harding has led efforts on climate change, paleo hydrology and “big river” modeling for the Colorado Water Conservation Board as part of the Colorado River Water Availability Study.  Mr. Harding has also directed the development of climate-impacted flow data for the U.S. Bureau of Reclamation, and is leading work on a statewide analysis of climate change impacts for the Oklahoma Water Resources Board.  He is currently leading a study of the impact of oil shale and other energy development on water resources in the Colorado, White and Yampa River basins in western Colorado.  He is employed at AMEC Earth & Environmental.  Mr. Harding has a B.S. in civil engineering from the University of Colorado and is a registered professional engineer in Colorado, Oklahoma and New Mexico. 

ABSTRACT: In the fall of 2008 the Colorado Water Conservation Board initiated the first phase of the Colorado River Water Availability Study (CRWAS) to provide estimates of the amount of water available for development from the Colorado River within Colorado.  The foundation of a study of water availability is development of estimates of natural flows.  Because of the complex array of water rights, laws, compacts, court decrees and treaties that govern use of Colorado’s water, the CRWAS required estimates of monthly time series of naturalized streamflows at more than 250 locations in Colorado and throughout the Colorado River Basin.  In order to represent the reliability of water supplies, these time series were required to represent low-frequency drought and the projected effects of climate change on mean flows and the seasonal hydrograph.  This presentation will describe the methods employed to develop natural flow scenarios and will review some of the results. 

Erin Wilson, Leonard Rice Engineers, Inc.: “Impact of projected climate on agricultural demands and reservoir uses in Colorado”

Ms. Wilson's Presentation

Erin M. Wilson is a Principal at Leonard Rice Engineers, Inc. and has been a practicing water resources engineer for over 20 years. She has degrees in Geophysical Engineering from Colorado School of Mines and Civil Engineering from Colorado State University, and is a registered Professional Engineer. Her expertise includes water resource planning, consumptive use modeling, and surface water modeling.  Erin has been involved in the development of the Colorado Decision Support System for 12 years, and routinely uses the data and tools to assist her clients with water resources planning and water rights investigations.  Erin has helped her clients plan for their future water needs in every river basin in Colorado.

ABSTRACT: Academic organizations and, more recently, planning agencies around the world are investigating the global and regional effects of climate change in terms of increased temperature and changes in precipitation amounts and patterns.  The State of Colorado may be the first entity to use detailed water allocation models to analyze the potential impacts of climate change at the local level.  The Colorado Water Availability Study quantified the effect of projected changes in climate on natural streamflow within the basins tributary to the Colorado River.  Existing agricultural demands were revised to reflect the increases in temperature and changes in precipitation.  The projected natural streamflow and increased demands were then used as input into the State’s water resources allocation model, which represents existing water rights, agreements, and reservoir operations.  The results allow Colorado to understand how climate change may affect current demands, water availability, and reservoir operations.

Panel 2:  Facing the Future: Moving, Keeping, and Using Wisely Colorado’s Water (3:30-4:45)

Todd Doherty, CWCB:  “Alternative Agricultural Water Transfer Methods Grant Program”

Mr. Doherty's Presentation

Todd Doherty has 13 years experience in water resources management and policy.  He has been with the Colorado Water Conservation Board since 1996 and works in the Water Supply Planning section.   This section works on long range water resources planning efforts to help the State manage its future water supply needs.  He manages two grant programs that provide significant financial assistance to help plan and implement water management and water storage projects:  the Water Supply Reserve Account Grant Program and the Alternative Agricultural Transfers Grant Program.  Todd received a Masters in Urban and Regional Planning from the University of Colorado in 1998 and a BA in Geography from the University of North Texas in 1994.

Abstract:  Colorado’s population is projected to nearly double from 4.8 million to upward of 10 million people in 2050.  The South Platte basin alone is forecasted to grow from 3.3 million to 5.8 to 6.8 million people.  By 2050, Colorado will need between 830,000 and 1.7 million acre feet of additional water for municipal and industrial needs. 

Water providers have identified specific projects that they plan to implement to meet their future water demands.  If 100% successful, these projects could yield approximately 511,000 acre feet.  Yet there still remains a water supply gap.  A large portion of the gap will likely be through agricultural transfers. 

In response to concerns that some water transfers may have negative third-party effects such as impacts to the agricultural sector and rural economies, the Legislature authorized the CWCB to develop a grant program to facilitate the development and implementation of alternative agricultural water transfer methods.   Since its inception in 2007, the CWCB has awarded $1.5 million in grants. These projects include rotational fallowing programs, water leasing-sharing programs, interruptible supply agreements to name a few.  The purpose of this session is to provide an overview of the projects and to discuss the challenges facing these alternatives to permanent agricultural dry-up of irrigated lands.

ABSTRACT: The Arapahoe Grasslands Conservation Area is a 17,085-acre property held in trust by the Colorado State Land Board and is located in Arapahoe County in the Coal Creek and Box Elder Creek watersheds.  The Conservation Area is in the eastern plains of Colorado within the Central Shortgrass Prairie Ecoregion.  The rolling hills are covered with short- and mid-grass prairie and the floodplains contain a mosaic of riparian plains cottonwood woodlands, willow shrub lands, sandy washes and herbaceous wetlands.  These plant communities support diverse, abundant wildlife populations.    The Conservation Area is unique because it is such a large protected area with relatively little human disturbance close to an urban area.  The Conservation Area is located immediately east of the rapidly expanding east edge of the City of Aurora.  The intermittent surface flows and shallow ground water that support the plant and wildlife communities in the Conservation Area are threatened by decreed conditional water rights that could potentially divert all surface flows and pump the shallow ground water to below the root zone of the riparian vegetation.  In addition, foreseeable upstream development could alter surface flows to the Conservation Area.  In 2009, ERO Resources Corporation completed a 1-year hydrologic study of the Conservation Area, collecting meteorological data, measuring stream flows, wetland and pond water levels, shallow ground water levels and monitoring the effects of current shallow ground water pumping in part of the Conservation Area.  ERO developed a ground water model to predict the effects of various surface and ground water rights development scenarios on stream flows, shallow ground water levels, and, consequently, on the vegetation and wildlife communities within the Conservation Area.  Based on the model results, ERO presented alternative water rights development scenarios to reduce or minimize impacts to the water-dependent ecosystems at the Grasslands.  In addition, based on available foreseeable nearby development plans, ERO completed surface water modeling to estimate the increased runoff flows that might occur within the Coal and Box Elder Creek watersheds due to the increase in upstream impervious areas (primarily roads, roofs and parking areas).  Conservation constraints and opportunities, as well as recommendations for the existing conservation plans, were provided based on the results of the hydrologic study.          

Gary Barber, Manager, Pikes Peak Regional Water Authority, “Front Range Groundwater: Scarcity and Opportunity”

 Mr. Barber's Presentation

Gary represents the El Paso County Water Authority, the Pikes Peak Regional Water Authority and manages two Metropolitan Districts, quasi-municipal governments formed to provide public services and resolve water issues of various types. He is currently chairman of Arkansas Basin Roundtable, a collaborative group of representatives from the counties, cities and special interests in Southern Colorado, attempting to address the consumptive and non-consumptive needs for water in the future.

ABSTRACT: The Statewide Water Supply Initiative of 2004 identified “gaps” in the future municipal water supply but made a basic assumption that the Denver Basin aquifer, a primary source of supply for many Front Range communities, would continue as a source of supply into the future.  The Executive Summary of SWSI did identify “sustainability and reliability” of these sources as worthy of further investigation.  The Arkansas Basin Roundtable has recently submitted a report: A Resource Document: Projects and Methods to Meet the Needs of the Arkansas Basin, that assumes that by the year 2030 the deep aquifers of the Denver Basin will be too expensive to serves as a source of supply, and have therefore increased the “gap” proportionately.

Does this future scarcity represent an opportunity for underground storage?  What about storage in the alluvial aquifers of the designated basins?  Can these efforts succeed under current law?

Panel 3:  Glimpsing Colorado’s Water Future (9:00-10:30)

Tim Carlson, Research & Policy Director, Tamarisk Coalition: “Tamarisk in Colorado: Its Real Impact on Water Supplies”

Mr. Carlson's Presentation

Mr. Carlson has more than 35 years of experience in the environmental field working in the private sector with various cities, states, Federal agencies, and with numerous non-profit organizations.  During this period he has facilitated several high level peer reviews for national laboratories and federal agencies on complex environmental problems.  One career achievement of note is his work with the Department of Energy and State Department developing environmental research opportunities for displaced scientists at the end of the Cold War.  Over the past eight years, Mr. Carlson established and directed the Tamarisk Coalition, a non-profit alliance of state and federal agencies, private organizations, and landowners working to restore riparian lands impacted by invasive plant species.  Mr. Carlson is a past member of the Invasive Species Advisory Council to the National Invasive Species Council.  He has also served on research grant review panels for the Bureau of Reclamation and NASA. 

ABSTRACT: Tamarisk, a non-native tree that is pervasive along western rivers, has long been considered a heavy water user that competes with and displaces native plants, and degrades wildlife habitat. Much time and effort has been devoted to the removal of tamarisk in an effort to restore streamside vegetation and save water.  Recently, the U.S. Geological Survey and U.S. Bureau of Reclamation produced a report that suggests that these efforts may be misguided.  A key finding of this science report is that native streamside plants such as cottonwoods and willows typically consume as much water as non-native tamarisk, also known as saltcedar.

Another complete assessment of the hydrologic impacts of tamarisk was performed by the seven states that make up the Colorado River Basin titled, Colorado River Tamarisk and Russian Olive Assessment (December 2009).  This report – authored by nationally recognized experts in the field of plant water use, potential water savings, and site restoration in tamarisk infestations identified that water savings are possible.  So, how should water managers in Colorado interpret these diverse findings?

Roundtable Discussion: Energy For the Future?  Understanding the Risks and Benefits of Uranium Development in Colorado (10:45-12:15)

Frank Filas, Environmental Manager, Energy Fuels:  “Water Impacts of Uranium Development in Colorado”

Mr. Filas's Presentation

Frank Filas is a professional engineer with 30 years of experience in mining and environmental engineering and is the Environmental Manager for Energy Fuels Resources Corporation. Energy Fuels is currently permitting the Piñon Ridge Uranium and Vanadium Mill in Montrose County, Colorado. Frank has a bachelor’s degree in mining engineering from the University of Wisconsin – Madison and a master’s degree in environmental science and engineering from the Colorado School of Mines. Prior to joining Energy Fuels, Frank worked in a variety of engineering, environmental, and managerial positions for mining and engineering consulting firms, primarily in the western United States. His environmental expertise includes site permitting, permit compliance, environmental audits, site decommissioning and cleanup, mine and mill reclamation, surface and ground water evaluations, and water treatment. Mine site experience includes working as a miner, mine engineer, foreman, and shifter in both surface and underground mines.

ABSTRACT: The uranium mining industry today is strictly regulated by local, state, and federal regulatory and land-managing agencies. New mines are built with substantial environmental controls including water treatment facilities, water diversion and erosion control structures, environmental monitoring plans, and fully-bonded reclamation plans. Historic mines are also often re-opened, which allows for remediation and reclamation of pre-law impacts.

Current laws and regulations also provide strict guidance for siting, building, and operating uranium mills. For example, the proposed Piñon Ridge Mill has secondary containment and leak detection and recovery systems throughout the mill and waste disposal areas. There is no groundwater under most of the site and, where present, it is approximately 450-feet deep. There are no perennial streams in the vicinity of the mill and all runoff and direct precipitation on the site will be contained on the site. Essentially, the mill is designed to be a zero-discharge facility with minimal impact to the surrounding environment.

Ronald D. "RON" Henderson is a native of Colorado, born in Delta County, graduated the University of Colorado Zoology 1970, ( 1970-1989 the following simultaneously) former owner transit mix concrete company,  former dirt excavator operator, former gravel extraction operator, former Chairman of the Montrose County Planning Commission, former President of the Chipeta Water Co. Montrose County, currently an active 22 year veteran of the real estate wars, and now Chairman of the Montrose County Board of County Commissioners. During the last 15 years, Ron has spent time traveling in Mexico, Nicaragua, Peru, Australia, China. Ron has a deep and abiding interest in his Country, State, and County tempered by his life experiences.

ABSTRACT: Ronald D. Henderson has been an unofficial student of water, fresh water, availability and usage all his life. He has become familiar with the ongoing problems and benefits of fresh water throughout his life's work which also includes briefly holding a waste water certificate .  He also completed Attorney Clay's 2 day water law course 5 years ago. Being a County Commissioner in a county including 3 drainage basins, 70% of the county land mass owned by FS and BLM, 4 possibly endangered native fish species, one of the richest mineral belts in the US, and in the process of permitting the first new Uranium Mill in the USA in 25 years has brought the importance of water to a center focus for Commissioner Henderson. Commissioner Henderson recognizes this vital resource is crucial for agricultural, municipal, commercial, industrial, and recreational sustainability and growth, as well as sustaining native species.

Harold Shepherd, Executive Director, Red Rock Forests

Harold Shepherd is the Executive Director for Red Rock Forests located in Moab, Utah and the staff attorney for the Center for Water Advocacy which is a non-profit legal entity that focuses on water issues throughout the West.

Harold is the author of “Compromising Democracy, The Rise and Fall of the Second Conquest of Western Rangelands.” He has published several law review and other articles focusing on water and Indian law topics and produces a radio show that is broadcast by KZMU in Moab addressing the availability of water in the western United States.

ABSTRACT: Calls for nuclear revival have led to rampant mineral and water speculation in and around Utah and an industry that is looking to the uranium rich iconic mountain and canyon country. A nuclear power plant in Green River, Utah could also be the epicenter of any future oil shale boom and the corresponding impacts on water availability in the state. Many water experts speculate that the already over-appropriated river systems in Utah simply cannot accommodate such development. A case in point is the Green River nuclear plant, which would have access to a 1964 Kane County water right for 29,600 acre-feet per year. If the river drops, the plant would have rights to what remains, placing it ahead of many other water right holders in southern Utah. In addition, adding water diversions for uranium together with other energy development could cause state water courts to cut off existing water users once Utah exceeds its allocation under the Colorado River Compact.

Panel 4:  Past, Present and Future Efforts to “Make” More Water in the Arid West (1:30-3:00)

Carol DeAngelis, Area Manager for Western Colorado, USBR: “Stretching Existing Supplies”

Jon Monson, Director, Greeley Water and Sewer Department: “A Secure Water Future: Greeley Water’s 4 Point Plan”

 Mr. Monson's Presentation

Jon Monson has a master’s degree in Sanitary Engineering from Georgia Tech and over 30 years experience in the water and wastewater field, about half as a consulting engineer and half as municipal utilities director.  He has done everything from designing an expansion of a sewer plant serving 150,000 people to being the chief engineer and bottle washer on a one-man pilot plant testing advanced waste treatment technologies on textile mill effluents.  As Greeley’s Water and Sewer Director, he has overseen development and implementation of Greeley’s water master plan, including the 4 Point Plan, to secure the City’s water future for the next thirty years.

ABSTRACT: Aging infrastructure, limited water supplies, and increased competition for water are serious challenges for water utilities.  The City of Greeley’s Four Point Plan for securing a reliable water supply includes improving water conservation, strengthening infrastructure, continuing water acquisition, and expanding storage. Greeley now has one of the strongest conservation programs in the state.  The water utility also has significant funding in place for maintaining infrastructure.  Greeley continues an almost 20-year history of leasing water back to farmers after purchase but is quite interested in alternatives such as rotational fallowing if they can meet the conditions of permanence and reliability.  And in terms of storage, Greeley has recently completed an innovative, experimental “Shared Vision Process” which involved such entities as The Nature Conservancy, Trout Unlimited, the US Forest Service, the Colorado Division of Wildlife, and EPA in water resource planning. 

Professor Mark Bird, College of Southern Nevada: “Nine Ways to Reduce Desalting Costs by 50 Percent”

Mr. Bird's Presentation

Mark Bird is a professor at the College of Southern Nevada.  He has been a full-time instructor at CSN since 2002.  Previously, he was a water planner with the U.S. Department of the Interior for a decade.  After leaving Interior, he has authored over 40 water-related articles.  His water articles have appeared in over 10 publications including the San Diego Union Tribune, the Tampa Tribune, and the California Engineer.  He is the sole inventor of a U.S. water-related patent.  His water articles were publicly recognized by former Nevada Governor Mike O’Callaghan    He has been invited to testify on water before a U.S. Senate committee.

ABSTRACT:  When most people think of seawater desalting, they think of oil-powered plants built in places like Saudi Arabia in the 20th century. There are other choices in the 21st century. Yet in a few locations in the US and the world, there are current plans to use 19th century pipeline technology to transport water over 200 miles! In addition to the six techniques identified in this presentation, there are certain to be other ways to reduce the costs of seawater desalting by more than 50 percent. Innovative ways to lower the costs of desalting have the clear potential to do at least as much good for humanity in the next 25 years as computers

Roundtable Discussion: Our Evolving Understanding of the Impacts of Climate Change, and What Can Be Done About It (3:15-4:45)

Tom Painter, Scientist IV, Jet Propulsion Laboratory/Caltech and University of California, Los Angeles

 Major area of interest is snow hydrology, radiative impacts of light-absorbing impurities on snow and glacier melt, remote sensing. B.S., Colorado State University, 1989; M.S., University of California, Santa Barbara, 1996; Ph.D., University of California, Santa Barbara, 2002.  Programmer, Climate System Modeling Program, National Center for Atmospheric Research (1992-1994); CIRES Postdoctoral Fellow, University of Colorado (2002-2003); Research Scientist I/II at National Snow and Ice Data Center, Boulder, Colorado; Assistant Professor of Geography at University of Utah (2007-2010); Scientist IV at Jet Propulsion Laboratory/Caltech (2010-present); Visiting Adjunct Researcher at UCLA Joint Institute for Regional Earth System Science and Engineering (2010-present); Assistant Adjunct Professor at UCLA Department of Geography (2010-present). Member, European Geosciences Union, International Glaciological Society, and Western Snow Conference.  Chairman, organizer of the Working Group on Light-Absorbing Impurities in Snow and Ice. Vice-Chair, Cryosphere Focus Group of the American Geophysical Union.

ABSTRACT: Disturbance of desert soil surfaces in the southwest US beginning in the mid 1800s led to 5-fold increase in dust loading to the mountain snow cover of the Colorado River Basin (CRB).  This increase in dust absorbs additional solar radiation through its decrease in snow albedo, and accelerates snowmelt, shortening snow cover duration by approximately one month.  Data from the growing network Western Energy Balance over Snow (WEBS) shows that present day dust concentrations in snow cause daily average radiative forcing of 25 to 110 W/m2 (global average anthropogenic greenhouse gas forcing is 1.6 W/m2) in the east central CRB over March/April/May, with instantaneous forcings reaching greater than 400 W/m2.  Snow cover duration is shortened by 25 to 50 days and the associated extension of the growing season enhances evapotranspiration.  These combine to bring a 3-week earlier peak runoff in the Upper Colorado and a reduction in the magnitude of annual runoff.

Ben Harding, AMEC Earth and Environmental: “Can We Adapt to Climate Change by Mitigating Dust? A Possible Win-Win Approach”

Mr. Harding's Presentation

BIO:  See Panel 1

ABSTRACT: Climate change impact studies on snowmelt-driven systems agree on one thing:  higher temperatures mean that snow will begin to accumulate later in the winter and will begin to melt earlier in the spring.  This, in turn, means that less water will be stored in snowpack and that runoff from that snowpack will come earlier in the spring.  This change in timing will have an important effect on the performance of water supply systems.  At the same time, we are also beginning to learn that deposition of dust originating from rangelands to our west and southwest has accelerated snowmelt and runoff for more than a century.  Mitigation of dust emissions on arid western rangelands could help us offset the effect of increasing temperatures on the timing of spring runoff.  This presentation will describe one possible win-win approach for accomplishing this mitigation.

Professor Dave Marchetti, Western State College

Dr. David Marchetti is an Assistant Professor of Geology at Western State College of Colorado. His research specialties include geomorphology and Quaternary geology and the geochemistry of low-temperature, near-surface geologic systems.

ABSTRACT: The stable isotopes of hydrogen and oxygen (18O, 16O and 2H, 1H) are incredibly powerful tracers of water movement within the hydrologic cycle. In this talk I will discuss the basic science behind stable isotopes and their applicability to water science, policy, and climate change.

Taryn Hutchins-Cabibi, Drought and Climate Change Technical Specialist, CWCB: “Drought, Climate Change, and Colorado”

Taryn Hutchins-Cabibi works on Drought Planning and Climate Change for the Colorado Water Conservation Board. Taryn conducts research and analysis of existing drought planning efforts; and provides technical assistance to water providers on the development, implementation, and monitoring of drought mitigation planning programs, including managing the revision of the Colorado State Drought Mitigation and Response Plan.

Taryn also provides technical expertise for the CWCB’s participation in regional efforts to analyze the impacts of climate change on water resources; including addressing issues concerning uncertainties and vulnerability in water resource planning & management, focusing primarily on climate change and implementation of water management strategies.

Prior to CWCB Taryn worked in the nonprofit sector on the balance between human water demands and protection of the natural environment. She has authored and co-authored numerous comparative analyses on western water issues.  She has also worked with the US EPA on climate change. 

ABSTRACT: In Colorado, temperatures have increased by approximately 2°F between 1977 and 2006. Increasing temperatures are affecting the state’s water resources and will continue to into the future. The impacts on water resources are also likely to affect other sectors statewide from agriculture and tourism to the overall economy.  Better understanding these potential impacts will enable the state understand how to adapt. 

Climate change, together with natural variability and increasing demand, may also lead to the State of Colorado and the region to experience drought conditions rarely observed in the historic record. Preparedness is the key to successfully addressing the challenges of increasing drought risk and demands on water availability. Drought preparedness includes drought early warning and mitigation planning, implementation of proactive adaptation measures, and increased public awareness.

The CWCB is helping water managers by supporting planning efforts on a local, regional and statewide basis. CWCB is participating in and conducting studies that examine the potential influence of climate change on the state’s water resources and other related water dependent sectors (i.e. skiing, rafting, agriculture, etc), how increases in temperature may influence the severity of drought events, how we can better assess our vulnerability, and how state and local decision makers can better prepare.

Panel 5:  Landscape Water Conservation for New Construction: Carrot, Stick, or Mind Your Own Business (9:00-10:15)

Facilitator: MaryLou Smith, Policy and Collaboration Specialist, Colorado Water Institute, Colorado State University      

After 35 years as vice president and co-founder of Aqua Engineering, Inc., MaryLou joined the Colorado Water Institute at Colorado State University to continue providing water policy collaboration services. Her work revolves around group process design and facilitation for various stakeholder groups including roundtables and work groups of the Colorado Interbasin Compact process; water conservancy districts; ditch companies; and agricultural and environmental organizations. Agricultural/urban/environmental water sharing strategies and the integration of land use planning with water supply planning is of prime interest.   

MaryLou grew up on cotton and alfalfa farm irrigated by wells in eastern New Mexico. She earned a master’s degree in educational psychology from New Mexico State University and received facilitation and mediation training from CDR Associates.  She served twelve years on the Fort Collins Water Board, and currently serves on CSU’s  Water Archives Advisory Board.

Abstract: Colorado’s legislatively created Interbasin Compact Committee (IBCC) and Basin Roundtables have been attempting to narrow in on solutions for filling the anticipated future gap between water supply and demand. One strategy under consideration is water conservation. At a recent IBCC meeting, one member questioned what’s keeping us from preparing now for landscape conservation standards so that when the economy recovers and we start building homes again, those standards are in place. This panel is a step-by-step look at what those standards might be, whether they would be mandated or incentivized, and what might stand in the way of their actualization.

Kim Calomino, Vice President of Technical and Regulatory Affairs, Home Builders Association of Metro Denver:  “Best Ways to Work with Homebuilders to Conserve Water in Colorado Landscapes”

Ms. Calomino's Presentation

Kim Calomino is the Vice President of Technical and Regulatory Affairs for the Home Builders Association of Metro Denver.  Calomino heads the department responsible for developing and delivering the association’s technical training, educational and certification programs in the areas of quality construction, energy- and resource-efficient building, stormwater and erosion control compliance and worker safety.  Calomino also heads up the HBA’s advocacy and government relations efforts on regulatory matters impacting the industry.  Calomino also served as Director of Built Green® Colorado, the HBA’s voluntary statewide green building program, from 1995 through its closure in 2009.  Under Calomino’s leadership Built Green became the largest, most widely-recognized and successful residential green building program in the nation.  Built Green was widely credited for helping “mainstream green” and was used as the model for many of the green building programs that have emerged across the country and in Canada in recent years.

Abstract: Certainly, residential water conservation is one component of addressing the state’s water supply problems; however, it is only a small part of the overall picture.  Colorado’s home builders have been working for decades to provide homes with state-of-the-art, affordable, water conservation features for both inside and outside the home.  The question posed to this panel – the feasibility of statewide incentivizes or mandates on landscape water conservation in new home construction – assumes major conservation gains remain to be had in new home landscaping and operates on a false premise that new residential development will play a major role in future water shortages. In light of the fact that municipal water use (which includes both indoor and outdoor residential use) accounts for only 5-7 percent of the state’s water use, and the fact that major steps have already been take to reduce new residential water use, additional legislation in this area will do little to produce additional water savings. Until water providers and elected officials are willing to acknowledge the water loss and waste that occurs with older, existing housing stock, Colorado will make little progress in residential water conservation.

David A. Kanzer, Colorado River Water Conservation District:  “Selenium—The Unintended Consequences of Water Use”

Although he’s a non-native Coloradoan, having been raised in suburbia, outside of Boston, Massachusetts, Kanzer is acutely aware of the water resource issues facing western Colorado (including the invasion of non-natives). Over the last 16 years, Kanzer has worked on the numerous water quality and quantity issues facing the Colorado River Basin, as a Senior Water Resources Engineer for the Colorado River Water Conservation District in Glenwood Springs. Recently his efforts have been primarily focused on the Gunnison sub basin. Providing for sufficient water with sufficient quality for a diverse array of beneficial uses is a career challenge that is not taken lightly or impatiently.

After originally moving to Colorado to pursue a lucrative career as a ski bum, Dave was lured by the poverty of academia at the Colorado School of Mines where he completed his bachelors and masters degrees in geological engineering.

He resides in Glenwood Springs with his wife and two boys, takes his selenium supplements daily and anxiously awaits the snowfall not only to replenish our critical water resources.
