Aquifers shrink on Columbia Plateau

Columbia PlateauSubsurface water is ebbing more than two feet per year in the arid plateau crossing parts of Washington, Oregon, and Idaho, according to the U.S. Geological Survey.

The Columbia Plateau covers an area roughly the size of Ohio and serves nearly 1.3 million people. The USGS drew its conclusions after studying 60,000 wells. In particular, scientists have kept a wary eye for some time on the Odessa aquifer, which serves four counties in Washington, and an aquifer near Umatilla.
