Summary

A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of the hydrologic system to implement effective water-resource management strategies. The U.S. Geological Survey (USGS) Groundwater Resources Program assessed the groundwater availability as part of a national study of regional systems (https://pubs.usgs.gov/circ/1323/). The CPRAS assessment includes the status of groundwater resources, how these resources have changed over time, and development and application of tools to estimate system responses to stresses from future uses and climate variability and change. A major product of this assessment [...]

Purpose

The groundwater flow model was developed to improve the understanding of the hydrogeologic system and groundwater availability of the Columbia Plateau aquifer system. The model was used to estimate water-budget components of the hydrogeologic units composing the groundwater system, and to evaluate groundwater availability under existing land- and water-use conditions and possible future climate conditions representing an increase in pumpage demand as a result of a warming climate. The development of the model input and output files for the CPRAS model included in this data release are documented in the U.S. Geological Survey Professional Paper 1817 (https://doi.org/10.3133/pp1817) and the modeling report that documents the construction and calibration of the model Scientific Investigations Report 2014-5127 (https://doi.org/10.3133/sir20145127)
