Isotope values in the Willamette River are from both Portland and Corvallis Oregon, and were collected once or twice a month for 13 years (2011 - 2013).  Isotope data are provided for small spatially distributed watersheds across the basin and samples were collected once a year during summer lowflow, and used to test the temporal stability of the Willamette River Basin Isoscape developed in the following paper: Brooks, J.
