Description This report characterizes the groundwater contribution to the Wenatchee River and its major tributaries including Icicle, Mission, Peshastin, Chumstick, Nason, and Brender creeks. Groundwater data from 54 mini-piezometers installed at selected sites were compared to surface water data to evaluate the dynamics of the groundwater and surface water system. Gaining and losing river reaches were identified using hydraulic gradient measurements and water temperature profiles. Additionally, historic groundwater quality data were evaluated to support the temperature and dissolved oxygen Total Maximum Daily Load (TMDL) assessments.

Errata of September 2007: Tables 4-9 were modified, and a paragraph was added under Data Quality Objectives, Blanks. These modifications do not affect the statistical analysis of the overall dataset, change the conclusions, or significantly alter the results of the study.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
