Water stargrass biomass and stream metabolism estimates on the Lower Yakima River (2018 - 2020)

This dataset provides information collected at three stream sites on the lower Yakima River in Washington State during 2018 to 2020 by the U.S. Geological Survey. Sample locations included the Yakima River at Prosser, WA (site ID, 12509489), the Yakima River at Kiona, WA (site ID, 12510500), and the Yakima River at Van Giesen bridge near Richland, WA (site ID, 12511800). Water stargrass biomass was collected six times from August 2018 to August 2020 from all 3 sites. Plant samples were dried and areal mass in grams per meter squared was determined. This data is provided in the file “Yakima.biomass.csv”.

In addition, stream metabolism was modeled at 2 sites, the Yakima River at Kiona, WA from June 2018 to October 2020, and Yakima River and at Van Giesen bridge near Richland, WA from August 2018 to March 2020 using the streamMetabolizer package in R. For each site, four files are provided; (1) the input data, which includes continuous dissolved oxygen, solar time, water temperature, light, and stream depth, (2) the output file containing the daily metabolism estimates, (3) a site-specific html 'guide' for running the streamMetabolizer package in R, and (4) a README text file explaining in detail what the files contain. Model input data were downloaded directly from the USGS National Water Information System (NWIS) (dissolved oxygen and temperature), downloaded directly from data loggers deployed in the field (light and depth), or calculated in the StreamMetabolizer program (DO saturation and solar time).
