West Plains Hydrogeologic Framework

The main water source for the West Plains are aquifers found in the Columbia River Basalt Group (CRBG) formations, overlying sediments, and interbedded sediments. In some areas of the West Plains there are documented water level declines ranging from 15 to 120 feet which has given rise to concerns about the sustainability of continued and increasing use of the water resource. While there has been significant amount of hydrogeological data collection and analysis there is a need for a comprehensive analysis and documentation of the West Plains hydrogeologic system.

Project Goals

The goal of this project is to gather, evaluate, analyze and synthesize all existing hydrogeological data and studies to develop and document a detailed assessment of the hydrogeological framework and a conceptual model of the groundwater flow system of the West Plains.
