Hydrogeologic boundary assessment for the Pullman-Moscow Basin. Project completion report Item Info

The hydrogeology of the local Basin has for many years been the source of interesting scientific discussion. At issue are the classic points surrounding water quantities and the sustainability of current and projected pumpages. In addressing those issues, two major contentions arise: the areal extent of the corresponding aquifer(s) and the recharge it receives. Recognizing the latter has gotten most recent attention, it is the question of size of the Basin to which this work has been directed. Here, we examine the historical evidence of the reported geology and water records to postulate a fairly radical physical picture of the Grande Ronde aquifer and its western extent along the Snake River. IN particular, an examination is made of the possibility of a "no-flow" barrier in that area, wherein explaining the unusual piezometric heads known to exist in the region. For illustration, changes are made to the existing model of the Basin (given by Lum et al., 1990) to include this barrier element. Comparisons are made in a before and after format, with recommendations being given for possible model and data collection improvement.
