| Description | Instream mini-piezometers and a seepage run were used to examine the surface water/groundwater interchange within the Walla Walla watershed. This study determined that the upper areas of the watershed were predominately losing (surface water discharging to groundwater) and the lower reaches were gaining (groundwater discharging to surface water). The Touchet River, Walla Walla River, and Mill Creek were losing in their upper reaches. The Walla Walla River and Mill Creek basins are composed of coarse gravel in the upper portions and fine-grained deposits in the lower portions. This distribution of materials results in groundwater discharging to surface springs which is more significant in the western part of the basin, at the confluence of the Touchet and Walla Walla rivers. |
