This dataset contains the results of water quality sampling efforts in the iUTAH GAMUT watersheds (Logan River, Red Butte Creek, and Provo River). There were two separate sampling and analysis efforts:
1. A "synoptic" effort that involved sample collection every month at a number of sites in 2013-2014. For this effort, samples were analyzed for total phosphorus and total nitrogen, total coliform, E.coli, and water isotopes.
2. A "biweekly" effort that involved sample collection every two weeks and a smaller number of sites (mostly at GAMUT aquatic stations) in 2014-2016. For this effort, samples were analyzed for species of nitrogen and phosphorus, dissolved organic carbon, suspended and volatile solids, total coliform and E.coli, chlorophyll-a, and fluorescence indices.

In all cases, grab samples were collected from the thalweg of the channel. For the biweekly effort, samples were filtered for analyses of dissolved species, and filters were retained for TSS and VSS analysis. Nutrient, organic matter, and chlorophyll-a analyses were performed at the Aquatic Biogeochemistry Laboratory at Utah State University. Isotope analyses were performed at the Stable Isotope Ratio Facility for Environmental Research at the University of Utah. Bacterial analyses were performed either at the Aanderud Laboratory at Brigham Young University or by technicians in the field. Detailed collection and analyses methods are described in the files.

The current Excel files are organized with worksheets corresponding to People and Organizations, Dataset Citation, Methods, Variables, Sites, Specimens, Processing Levels, Units, and Analysis_Results. The Specimens sheet includes detailed metadata on the collection of the specimens, including the date and time. The Analysis_Results tab includes detailed metadata on the analyses of the specimens and the numeric results. These two are linked via the Sampling Feature Code.
