Columbia Plateau Regional aquifer system Completed

By Water Resources Mission Area March 8, 2021

The Columbia Plateau regional aquifer system (CPRAS) covers parts of Idaho, Oregon, and Washington. It consists primarily of three basalt formations separated by confining units.

The primary aquifers of the Columbia Plateau regional aquifer system (CPRAS) are basaltic lava flows of the Columbia River Basalt Group and overlying basin-fill sediments. Generalized geologic units for the CPRAS include Overburden, Saddle Mountains Basalt, Mabton Interbed, Wanapum Basalt, Vantage Interbed, Grande Ronde Basalt, and Older Bedrock.

The data files listed below are supplemental to Three-dimensional model of the geologic framework for the Columbia Plateau Regional Aquifer System, Idaho, Oregon, and Washington (USGS Scientific Investigations Report 2010-5246). The report includes a description of methods used to derive the data.

Regional Groundwater Availability Studies

Regional groundwater availability studies enable information about groundwater to be integrated and consistent, so that this resource can be analyzed and understood on an aquifer–wide scale. These studies provide decision–makers with a better understanding of the status and trends in the Nation's groundwater availability.

Ground Water Atlas of the United States

PrefaceThe Ground Water Atlas of the United States presents a comprehensive summary of the Nation's ground-water resources and is a basic reference for the location, geography, geology, and hydrologic characteristics of the major aquifers in the Nation. The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. Results of the Regional A
