Utah Lake Water Quality Study
The Division of Water Quality is conducting a two-phased water quality study on Utah Lake to determine the role of excess nutrients on impairments to the aquatic life and recreational beneficial uses and to determine appropriate nutrient endpoints. An initial water quality investigation was completed in 2007 and subsequently put on hold to evaluation the relationship between in-lake water quality and ongoing ecological management strategies. This presentation will provide an overview of the project, progress to date, overview of ongoing research, and a discussion of the next steps.

DWQ initiated Phase 1 of the Utah Lake study in 2015 in response to nutrient related impairments identified in DWQ’s Integrated Report and in response to harmful algal bloom events on Utah Lake in recent years. Phase 1 of the study consists of four work elements led by DWQ staff and representative stakeholder subcommittees. Phase 1 work elements include: 1) Stakeholder Outreach and Public Involvement; 2) Data and Information Management; 3) Beneficial Use Assessment; 4) Bulk Load Analysis; and 5) Model Selection and Development.

DWQ anticipates completing the majority of the Phase 1 work elements in 2016 and launching a Phase 2 study to identify appropriate nutrient management scenarios. Phase 2 will further investigate water quality conditions in Utah Lake and will result in one of three alternatives: 1) Total Maximum Daily Load; 2) Site Specific Nutrient Criteria; or 3) Use Attainability Analysis.

The water quality model developed in Phase 1 will serve as the primary tool to evaluate the water quality and ecological responses expected from a reduction of nutrient inputs and the carp removal effort. This will require additional research to better understanding of the unique biological, physical, and chemical interactions in the Utah Lake system. DWQ and stakeholders will continue to work collaboratively throughout this study to develop scientifically defensible recommendation for meeting Utah Lake beneficial uses.
