Figure 13. Stratigraphic position (distance from the well bottom to the simulated top of Grande Ronde Basalt) compared with winter median water level measured in wells for shallow–deep well pairs from groups 3 and 14 near the Oregon Water Resources Department administrative areas in the Umatilla Basin, Oregon. Colors of points correspond to colors of shallow-deep pair circles in figure 10.
