Watershed Symposium 2024

Come and learn about the challenges of implementing a large-scale river delta restoration close to a major urban area in Utah County.

Full Abstract:
The Provo River Delta Restoration project is one of the largest ecological restoration projects completed in the Jordan River watershed. After 10 years of planning and almost 5 years of construction, this ambitious project has been completed and is now open to the public. The Delta was re-created where the Provo River enters Utah Lake and now provides habitat for the threatened June sucker to grow from larvae to juvenile and provides many recreation opportunities for residents and visitors to the area. With nearly five miles of new river channel, two-hundred acres of open waters, and complete public access to all areas, this will be a resource that is valued for generations to come. This presentation will provide insights into how to develop the needed partnerships to achieve something at this scale and we will discuss some of the challenges of implementing such a large project so close to a highly urbanized area. It required an ambitious vision, perseverance in the face of challenge, and lots of public outreach to get this project done. We hope you can go visit and get on the water, walk with your family, observe the abundant wildlife, and maybe drop in a fishing line at this great location that balances the needs of both fish and people.

Ever wonder what’s really going on in Utahns’ minds and hearts when it comes to water? A new values study conducted by Envision Utah, Utah Water Ways, and others helps us understand not just what Utahns care about, but why Utahns care about the things they do. These findings are invaluable for anyone in water policy or public messaging.

Full Abstract:
Envision Utah and Utah Water Ways, along with other partners around the state, just completed a landmark research project to understand what’s in Utahns’ hearts and minds when it comes to water issues. Our findings tell us not just what Utahns care about, but why Utahns care about the things they do. This research will provide invaluable insights for anyone involved in water policy or public messaging.

Among other things, we found that:

• Utahns have high awareness and concern about water issues — though not quite as high as some other western states.
• Many Utahns have a high sense of self-efficacy when it comes to water — they believe they can make a meaningful difference in water conservation.
• Utahns believe that state and municipal governments bear a lot of responsibility to reduce individual water use. 
• Utahns have some significant misconceptions about how water is used and what strategies would do the most to reduce household and community water use. 

In addition, our findings also include “values maps” that represent how Utahns connect water to their deeply held priorities. We also have findings related to landscaping preferences, effective messages to motivate individual behavior changes, and even the words and phrases that Utahns best respond to.

Attendees will learn the answers to these important questions (i.e., learning objectives):

• What does the public understand — and misunderstand — about key water issues?
• What water-related issues do Utahns most care about? Why do Utahns care about those issues?
• What are the deeply held values and beliefs that motivate their priorities? 
• What kinds of tradeoffs are Utahns willing to make to serve their priorities?
• How do priorities, values, and tradeoffs differ by region or other demographics?
• How do we most effectively communicate about water-related issues to motivate behavior change? 

This research is hot off the presses — symposium attendees will be among the first to see the results. The research was conducted with a week-long online focus group and a random-sample survey of 800 Utahns.

This study aims to identify major phosphorus origins in Utah Lake’s watershed, quantify phosphorus influx from each source to Utah Lake, visualize HAB occurrences, and assess the correlation between phosphorus levels and HAB distribution.

Full Abstract:
This study aims to identify major phosphorus origins in Utah Lake’s watershed, quantify phosphorus influx from each source to Utah Lake, visualize HAB occurrences, and assess the correlation between phosphorus levels and HAB distribution. To accomplish this goal, our research team conducted in-situ water sampling and nutrient concentration measurements. We utilized geographic information systems (GIS) and remote sensing geospatial techniques to categorize key phosphorus sources to Utah Lake, employed empirical models to quantify nutrient runoff, and leveraged Google Earth Engine (GEE) and ArcGIS Pro to automate the processing of Landsat images for visualizing HAB distribution in Utah Lake. The identified key nutrient sources include urban lawns, golf courses, parks, herbaceous, deciduous forest, evergreen forest, mixed forest, hay/pasture, and cultivated crops. Their respective total areas ranged from 9.5 km² to 1,775.7 km², with golf courses being the smallest and deciduous forests being the largest. Notably, urban lawns and cultivated crops, covering 337 km² and 344.41 km2, emerged as two significant phosphorus sources to Utah Lake, despite constituting only 7.5% and 7.6% of the total Utah Lake Watershed area, respectively. Furthermore, our analysis revealed a close correlation between HAB distribution and phosphorus levels in the lake. Prior studies on Utah Lake have focused primarily on phosphorus loading from wastewater treatment plants (WWTPs) and atmospheric deposition. While WWTPs are still the major phosphorus contributors to the occurrence of HABs, our findings suggest that land-derived non-point nutrient sources play a substantial role in triggering HABs in Utah Lake.

Development of the Great Salt Lake Basin Plan is underway and the Utah Division of Water Resources is excited to update you on the progress of the first-ever basin-wide water management tool. Implementation of the tool will ensure a resilient water supply for Great Salt Lake and all water uses, including people and the environment, in the basin.

Full Abstract:
The Utah Division of Water Resources is excited to share an update on the first-ever Great Salt Lake Basin Integrated Plan (GSLBIP). Since we presented at the 2023 Watershed Symposium, we’ve made significant progress, completing several key foundational tasks and paving the way for more impactful milestones ahead. These tasks will culminate in the creation of an important decision-making tool for improved water resource management. When the tools and research findings from the project are complete, decision makers will be equipped to make informed decisions about water planning in the Great Salt Lake Basin.

Once implemented, the goal of the Great Salt Lake Basin Integrated Plan is to ensure a resilient water supply for Great Salt Lake and all water uses — including people and the environment — throughout the watershed. As part of the 2024 GSLBIP update, the Division of Water Resources team will dive into how we’re actively bringing the recommendations in the GSLBIP Work Plan (completed in April 2024) to life. We will bring attendees up to speed on the planning and modeling approaches, discuss near-term milestones and begin exploring possible watershed management alternatives to be considered in the scenario-planning process. Alongside the development of an innovative water resource modeling tool, the GSLBIP is conducting important research that will shape and guide future water planning decisions. The Gap Analysis in the GSLBIP Work Plan identified over 150 potential projects that could enhance understanding of water flows in the Great Salt Lake Basin. Project partners honed in on eight key projects, and all are now officially underway, marking an exciting step forward in the plan’s progress. We will provide an update on those projects and explain how we envision them playing a pivotal role in future watershed planning.

A recent survey across the Intermountain West found that the foremost challenge facing wetland managers was increasing temperatures and drought. Through a survey of wetland managers working in state and federal agencies, we identified how changes in temperature and precipitation are affecting the region's wetlands and how managers are responding to those changes. Participants will learn about the most common strategies employed and the predictions that wetland managers have for the future. The session will give participants a chance to share ideas about how the results might be used to inform future policies to improve wetland sustainability in one of the driest regions of North America.

A native walk of the Bear River with the ancestors of the Bear River and the life ways it provided and must still provide.

Full Abstract:
The Northwestern Band of the Shoshone Nation has lived in the Bear River Watershed for over 13,000 years. The Bear River was the most important resources to our ancestors. It gave life. It was abundant with game, wetlands, drinking water, fish, and was a trail system for our people, and it always flowed into the Great Salt Lake. We would like to discuss our Tribal History of the Bear River and how we used it historically, how we used the Great Salt Lake, and how the depletion of these resources would be catastrophic to every in the Wasatch Front. We want to discuss food we used, grounds we farmed, and all the native plants that existed and how losing them is causing us to lose the river and a depletion in the Great Salt Lake. It'll be a native walking experience of the Bear River.

As Utah faces water scarcity, reevaluating water allocations to reflect the highest social value is crucial. By integrating social values into aquifer storage and recovery projects, communities can boost water's contribution to well-being, ensuring security, resilience, and equitable access for future generations.

Full Abstract:
Water resource management regimes allocate water across different users and, at least implicitly, across time. The traditional focus has been on satisfying the demands of municipal, residential, agricultural, and commercial uses. Increasingly, demands for water in Utah to support ecological functioning have been recognized. However, as communities grapple with the challenges of water scarcity, there is a growing recognition for the need to assess whether current allocations reflect highest and best use of water now and into the future. What is needed are allocations that get the most social value for each acre-foot buck. This requires determining a “social value of water” in each of its uses, including use now versus use in the future and in different circumstances — for example, in good and bad years for precipitation. This presentation explores the concept of assessing social values of water in the context of aquifer storage and recovery (ASR) projects. We show that by properly accounting for social values across all situations, the total contribution of water to social wellbeing in communities can go up, even as the physical amount of water is unchanged. Current approaches may be severely missing that mark. The presentation will highlight the importance of understanding and quantifying the broader economic and social dimensions ASR projects and other management actions and their potential to enhance water security, community resilience, equitable access, and economic activity for present and future generations.

The H2Oquirrh Vision Plan harnesses attention on the Oquirrh range’s washes and creeks and channels it into impactful improvements that have both environmental and community benefits. This talk will present the final version of the study, focusing on the vision, goals, and strategies that will steer the implementation of the plan.

Full Abstract:
There is heightened attention on water in the Great Salt Lake Basin, with dwindling water resources and a shrinking lake making national news. Drought has caused intermittent streams to have longer dry periods and changes in stormwater runoff have exacerbated issues with water quality and flooding. During this session, we will share the vision, goals, and recommendations developed for H2Oquirrh, a comprehensive vision plan for the waterways of Southwest Salt Lake County and the Oquirrh Mountain Range. The H2Oquirrh Vision Plan is an opportunity to harness attention on critical natural resources and channel it into impactful improvements that have both environmental and community benefits. It is one of the first plans to facilitate collaboration across jurisdictions with the goal of preserving open space, supporting natural hydrology, and connecting people to the outdoors in creative ways. The creeks and washes in the Southwest portion of the Salt Lake Valley, including Bingham, Rose, Midas, Butterfield, and Barney’s, Juniper, Wood Hollow, and Beef Hollow, have received less attention than the creeks flowing out of the Wasatch Range. Originating in the Oquirrh foothills, these waterways are significant environmental and natural systems that provide community benefits. Bringing attention to these creeks through the H2Oquirrh Vision Plan presents an exciting opportunity to build community-led solutions and explore new ways of supporting the interface between cities and their waterways. Over the last year, the project team has pulled topical expert feedback, community inputs, and design and engineering strategies to create a vision plan with a holistic regional approach. The plan identifies environmental, economic, and social goals to guide cities as they plan for future open space and development surrounding the waterways, as well as targeted strategies and actions that can steer implementation of the plan in the next five years. Small steps and grand visions work together to create this vision, with ideas ranging from aquifer recharge and native vegetation enhancement to low impact development (LID) and trail systems to benefit the entire downstream watershed. This talk will present the final version of the study, focusing on the vision, goals, and strategies that will steer the implementation of the plan. The multi-disciplinary presenters will provide a variety of perspectives on what went into the making of this plan.
