Know Your Flow!

Groundwater levels of the Palouse are dropping, and it will take a community-wide effort to reduce groundwater pumping and protect our aquifers.

our water resources


Water is a precious resource here on the Palouse. Our communities rely entirely on groundwater sources for drinking water and our surface waters have become contaminated with non-point source pollutants from agricultural and urban runoff. The Grande Ronde and Wanapum aquifers are the largest aquifers in our region. They are confined, meaning that there is an impermeable layer of substrate that prevents water from entering and recharging the aquifers. 

The rate at which we pump water from our aquifers is greater than the rate that water is added to them. As a result, our aquifers continue to decline and conservation efforts become increasingly more important.

To learn more about the state of our aquifers, visit the Palouse Basin Aquifer Committee's website.
