Abstract

Utah Lake is a large shallow eutrophic lake located in north central Utah. In recent years, the occurrence of frequent and sometimes toxic algal blooms has brought new urgency in understanding the cause and effects of eutrophication in Utah Lake. The drainage basin of Utah Lake is dominated by carbonate sedimentary materials and small pockets of phosphate rock occur. Given the bedrock geology and shallow nature of the lake, there has been uncertainty as to the natural trophic status and ecology of the lake prior to the settlement of Utah Valley. Thus, defining historical nutrient concentrations and sources in the water column and how these have changed will assist DWQ in defining numeric nutrient targets while the reconstruction of diatom, macrophyte, and zooplankton communities will assist in understanding how the trophic status and ecology of the lake has changed.
