Steering Committee Meeting Updates:
Utah Lake Water Quality Study

Steering Committee meetings take place on an as-needed basis following the phased study approach. The timing of Steering Committee meetings is based on the project timeline, Science Panel findings, and public outreach efforts. Next Meeting Steering Committee Meeting TBD Past Meetings

Utah Lake Science Panel:
Utah Lake Water Quality Study

The Utah Lake Science Panel was established by the Steering Committee in 2018 to provide independent and unbiased scientific advice to the Steering Committee. Science Panel members were selected to provide a full range of scientific expertise relevant to the unique characteristics of Utah Lake. The Science Panel is charged with guiding the development of …

Utah Lake Steering Committee:
Utah Lake Water Quality Study

The Utah Lake Water Quality Study Steering Committee is a 16-member committee representing a diverse group of stakeholders interested in protecting and improving water quality in Utah Lake through a collaborative, transparent, and consensus-based decision-making process. The Steering Committee was formed in 2016 by a stakeholder-led initiative to establish a formal process by which committee …

Phase 3: Implementation Planning for Phase 2 Criteria:
Utah Lake Water Quality Study

During the implementation planning phase of the study, the Steering Committee will review the recommendations of the Science Panel and formulate a plan that achieves and/or maintains water quality protective of designated beneficial uses while also balancing costs and benefits. During this review, the Steering Committee will: Evaluate current use designations and the scientific and …

Phase 2: Criteria Development:
Utah Lake Water Quality Study

The Steering Committee and Science Panel will evaluate the factors that impact the lake’s designated beneficial uses, including the factors that lead to harmful algal blooms on Utah Lake, during Phase 2 of the Study. This evaluation will guide additional research needed to address data gaps and develop site-specific numeric criteria for phosphorus and lake …

Model Development:
Utah Lake Water Quality Study

The selection and development of a water quality model of Utah Lake were initiated as part of the Utah Lake Water Quality Study. The primary objective of the model is to function as a decision-support and water-quality management tool to address eutrophication in Utah Lake. Key objectives for the Utah Lake nutrient model: Provide a …

Nutrient Loading Analysis:
Utah Lake Water Quality Study

Watershed delivery of flow and nutrient loading to Utah Lake are important for understanding how nutrients are processed in the lake and the resulting water quality of the lake. Simulations of in-lake water-quality conditions will use a series of in-lake water-quality and hydrodynamic models (EFDC and WASP). Since these models do not explicitly simulate delivery …

Water Quality Assessment and Analysis:
Utah Lake Water Quality Study

The Phase 1 Water Quality Assessment and Analysis had two primary objectives: DWQ performed a baseline analysis of several relevant water-quality parameters, trophic state indices (TSI), and lake-elevation data. The process included analyses of spatial and temporal patterns in water quality, relationships among water-quality parameters and TSIs, and relationships between water-quality parameters and lake elevation. …

Data & Info Management

Various agencies and organizations have monitored the ecology and water quality of Utah Lake and its tributaries for many years. The 2015 Utah Lake Water Quality Study (ULWQS) Work Plan identified the need for a robust and complete data set that would help scientists: Build a predictive water-quality model. Determine trends in water-quality conditions over …

Stakeholder Development

Stakeholder involvement is a critical component of the Utah Lake Water Quality Study. Outreach efforts ensure a collaborative process with engaged stakeholders to guide scientific analyses and regulatory decision making. The original stakeholder group assembled in 2015 consisted primarily of members of the Utah Lake Commission Technical Committee as well as representatives from the Utah …

Phase 1: Data Gathering and Characterization

For Phase 1 of the study, DWQ assembled a broad group of stakeholders representing a wide range of interests in the Utah Lake Water Quality Plan. Participants include representatives from local municipalities, publicly-owned treatment works (POTWs), and state and local governments. DWQ created subgroups of stakeholders to help inform decision-making for work plan element. The …
