This data will be used by Dr. Saito and her graduate student, Christa Fay, to construct models of the aquatic food web. We will correlate the resulting models and stable isotope data with measured water quality, hydrology, and results from passive organic samplers deployed by the USGS. Another graduate student, Jorge Arufe, is working with the USGS to develop a geographical information system database of the isotope, water quality, and organic contaminant data, along with degrees of urbanization and indices of biotic integrity to investigate correlations between these different data sets. Ultimately, it is hoped to integrate the food web model with water quality and hydrologic models of the Truckee River for potential applications for bioassessment and sustainable management of the Truckee River.
