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 …
