Location: The East River (ER) is a snow‐dominated, headwater basin of the Upper Colorado River Basin (UCRB) located in the western United States. The ER is the designated testbed of Lawrence Berkeley National Laboratory's Watershed Function Scientific Focus Area (WFSFA). The ER is considered representative of many snow‐dominated headwaters of the Rocky Mountains. The ER contains high‐energy mountain streams to low‐energy meandering floodplains and is eroding primarily into the Cretaceous, carbon‐rich, marine shale of the Mancos Formation.

Description

This data package contains hydrologic modeling input and output files for the East River (ER_PRMS.zip) and Copper Creek (CC_GSFLOW.zip) for water years 1987 to 2018. These data were used to generate simulated results published in Geophysical Research Letters (Carroll et al., 2019) describing the importance of interflow in generating groundwater recharge in the upper subalpine. The East River and Copper Creek are part of the Watershed Function Scientific Focus Area (WFSFA) located in the Upper Colorado River Basin, United States. The hydrologic model uses the U.S. Geological Survey coupled groundwater and surface water flow model (GSFLOW). Input and output files are askii format, while the model executable (gsflow.exe), source code, example problems and documentation describing model files is provided at the following U.S. Geological Survey website. https://www.usgs.gov/software/coupled-ground-water-and-surface-water-flow-model-gsflow. GSFLOW executables are compiled for either Microsoft Windows or Linux operating systems.
