Description In support of a TMDL analysis for Moses Lake, a study was conducted to examine the role of groundwater discharge in the lake’s nutrient budget. Samples where collected from a network of lake-bed piezometers, springs, and wells, and tested for phosphorus and nitrogen nutrients. Phosphorus concentrations were higher than the target water quality criteria for the lake (0.050 mg/L TP) at 75% of the stations tested. Data indicate that a combination of urban wastewater sources are the likely origin for the elevated phosphorus measured in the discharging groundwater. The results of this study are incorporated into a comprehensive analysis of lake loading published separately.
