Projects

This project works with social services and public health professionals, who are a critical part of the social infrastructure in community recovery, as well as rural community partners to understand the often overlooked community impacts of wildfire. WWA is partnering with CLIMAS, the Arizona and New Mexico CAP team, to explore these questions in Arizona, Colorado, and New Mexico.

The Challenges to Building Resilient Water Systems Webinar Series will run monthly from October 2024 through April 2025 and cover topics such as new climate monitoring and prediction tools, temperature and precipitation extremes and post-2026 Colorado River Basin water policy. In winter 2025, WWA will convene an in-person symposium on the Front Range of Colorado and Utah’s Wasatch Front to connect water managers with researchers to share recent research and climate resilience efforts

In Spring 2024, Western Water Assessment launched a new project focusing on understanding climate risks and building climate resilience within mobile home park communities. Mobile home park residents face unique and disproportionate exposure to climate related hazards, including heat, fires, and floods. Further, mobile home residents often are left out of many climate and disaster related assistance programs, due to the unique housing structure of mobile home parks. Addressing the needs of mobile home park communities is key to building climate resilience.

[Project 6]
Water system managers in the Intermountain West face enormous challenges navigating unpredictable streamflow forecasts, changing snowpack behavior, and the increasingly dangerous threat of wildfire to both water quality and quantity. In this project, we aim to engage directly with water system managers in an iterative project to (1) increase understanding of their perceptions of water system resilience, (2) identify key components of regional water system resilience across a range of scales from small rural systems to larger urban systems, and (3) convene cross-scale water manager conversations to support peer learning and identify opportunities to collaboratively build equitable and just regional water system resilience. This project stems directly from conversations with the US Forest Service, Northern Water, and Denver Water.

[Project 3]
In this project, we will engage with water providers, tribal representatives, agricultural and other water users, ecological interests, and recreational groups about future snowpack and streamflow conditions, increasing understanding of how they view water system resilience to compound hazards. This continued engagement is essential both to disseminate new research findings and to understand evolving information and planning landscapes.

Wyoming communities face increasing climate-related risks including wildfire, drought, flooding, and heat waves. This funding competition provided a rare and important opportunity to directly support adaptation and build climate resilience in communities in the state. Applicants provided brief, five-page descriptions of their projects. Proposals were ranked based on their demonstrated community interest, resources and networks in place to support the project, realistic budget and timeline, appropriate and sufficient partners, strong connection to their communities, clarity about how resilience or adaptation would be built through the project, their plan for communicating with WWA and leveraging of WWA resources, their plan for and potential impact of external outreach, and the quality, novelty, and innovation of their ideas.

The National Climate Assessment (NCA) is a congressionally mandated quadrennial report prepared and submitted by the US Global Change Research Program. The fifth iteration of this report (NCA5), published in November 2023, provides the scientific foundation to support informed decision-making across the United States.

WWA’s Liz Payton is the lead author of the water chapter. She built and led a team of 11 experts from across the country who work in academia, local utilities, state and federal agencies, and private consulting. They brought expertise in hydrology, climate science, groundwater, drought, extreme precipitation and flooding, water quality, snow, and water resources tools and data. The chapter analyzes current climate trends and projects future trends based on a comprehensive review and assessment of peer-reviewed literature and climate and infrastructure data.

The Intermountain West Climate Dashboard, which debuted in October 2012, is our most popular resource that provides information and graphics about current and forecasted regional weather, climate, and water information. Feedback from WWA stakeholders through multiple program evaluations and analyses of website traffic indicate that the dashboard is a very useful ‘one-stop shop’ for up-to-date climate and water information for WWA’s three-state region.

High-impact events cause the majority of societal costs related to weather and climate. They provoke societal responses that can either enhance or detract from long-term adaptation to climate risk. In 2015, WWA began a new research focus on extremes that is designed to place high-impact events in the context of historical climate variability and projected climate change, assess how the risk of these events varies over time and space, and examine how high-impact events interact with place-based vulnerability.

The snowtography handbook guides readers through the process of establishing their own snowtography and soil moisture monitoring stations. It offers guidance on site selection, snowtography options, equipment requirements, and installation. The instructions are based on snow-forest research and hands-on experience at multiple sites in Arizona, and in the San Juan National Forest in southwestern Colorado.

ACCESS is a collaborative project among researchers at Michigan State University and the University of Colorado Boulder funded by the National Science Foundation.
Led by Drs. Yadu Pokhrel and Lifeng Luo at MSU and Dr. Ben Livneh and Liz Payton at CU, the project engages with stakeholders throughout the Southwest US to assess whether current management practices can meet future water demands while maintaining environmental water requirements, and if not, whether there are alternative approaches to achieving water and environmental sustainability. The project uses a comprehensive modeling framework that integrates key drivers of hydrologic change and water management while also accounting for environmental water needs.

[Project 10]
Gateway and natural amenity region (GNAR) communities are those located outside of significant natural amenities, like national parks, public lands, ski areas, and scenic rivers. These communities are heavily dependent on nearby natural amenities for their economic well-being; as a result, they may be particularly hard hit by climate change. In this project, we will leverage the infrastructure and relationships developed by WWA Investigator Danya Rumore’s GNAR Initiative to identify rural community concerns related to natural hazards and collaboratively develop tools and resources to increase their resilience.

[Project 9]
When communities experience the impacts of compound hazards, responses are often reactive and it is often too late to respond in an efficient and effective manner. Just as academic disciplines are often siloed, sectors and decision-makers can be siloed from one another and not understand interconnections or linkages in decision-making. Social network analysis has been used to understand how information and resources flow through a system and how they influence adaptation actions. While social networks have been looked at retrospectively, they have rarely been assessed in a co-produced approach with stakeholders to proactively assess and shift networks to build system resilience.

[Project 8]
Planners, public land managers, and community decision-makers anecdotally understand and experience the importance of sense of place but may not understand how it can be leveraged to build adaptive capacity to help communities respond to and navigate change. In this project we will collect and compare data across the Intermountain West to better understand how sense of place might be leveraged to assist in adaptation efforts.

[Project 7]
Carbon-dependent communities are facing increasing economic pressures as fossil fuel industries decline, creating a major societal stressor in these communities. At the same time, they also face worsening climate impacts and other hazards, which can cause increasing vulnerabilities concurrent with decreasing adaptive capacity. This project focuses on small rural communities and tribes in Wyoming, addresses our understanding of adaptation needs in carbon-dependent communities, and explores opportunities for building resilience to compound hazards in our region. This project prioritizes the needs and perspectives of rural and tribal communities to support long-term resilience and build networks for future engagement and planning.

[Project 5]
Wildfires create hazards for lives and property through combustion and high temperatures, as well as their impacts to catchment source water. This project focuses on these water-related vulnerabilities, which include far-reaching effects on flood risks, on aquatic habitats, and on water treatment costs.

[Project 4]
Wildfire is a critical vulnerability for water systems in the Intermountain West, particularly those with intakes located in or downstream of forested areas. This project seeks to increase our understanding of the status of water system resilience in the context of changing wildfire risk. It will make key advances by explicitly quantifying the role of fine-scale, spatially distributed snowpack in wildfire risk/resilience under a range of historical precipitation/temperature conditions, as a way to anticipate future wildfire risks under climate change scenarios. The critical advances in scale will support the use of finer land surface/ecological classifications in wildfire risk assessments of future climate projections.

[Project 2]
This project aims to build water system resilience by increasing understanding of the impacts of persistent low streamflows on water systems that rely on surface water sources.

[Project 1]
This project supports water system resilience through use-inspired research that helps providers prepare for vulnerabilities due to seasonal water supply prediction errors. We will make meaningful advances in the understanding of existing water supply forecast vulnerabilities and identifying realistic potential adaptations for water systems.
