The increasing reliance on ground-water resources in the Portland Basin has prompted a need to evaluate the capability of the ground-water system to meet present and future demands. Toward this goal, the U.S. Geological Survey conducted a hydrogeologic study of the basin and is constructing a ground-water flow model of the aquifer system. This report describes one component of the study which involved mapping the extent, thickness, and boundaries of hydrogeologic units (aquifers and confining units) in the basin.
