A Long History


The story of human civilization is a story of fresh water. In the late 1800’s water burst from the ground in the Palouse Basin, with artesian wells producing up to 3 million gallons per day. This bountiful source of ancient fresh water led to the establishment of thriving communities on the Palouse. Since that time the water level in our precious aquifers has steadily dropped, making our current supply and use patterns unsustainable.

A New Committee


The original committee, made up of representatives from UI, WSU, Pullman and Moscow, was formed in 1967 to address concerns with declining ground water levels in the area.

PBAC maintains a network of water level monitoring instruments throughout the Palouse Basin, and funds a variety of research projects aimed at gaining increased understanding of the behavior of the basin aquifer systems. PBAC also manages a central clearinghouse of technical documents related to basin hydrogeology.
