Discover more about Spokane’s sole source of water by checking out the Spokane Aquifer’s Joint Board’s website. You can find out about aquifers in general, view the large Spokane Aquifer Atlas in .pdf format, get water conservation and water protection tips. For more technical information about the aquifer, the USGS has posted many studies about the Spokane Valley-Rathdrum Prairie Aquifer (its official name) online. You can even take a virtual tour of the aquifer from the Eastern Washington University’s Geology Department. - Spokane Government Librarian
