| Short Description |
The Chehalis River between the Thurston/Lewis County border (River Mile 60) and Adna (River Mile 86) hydraulically interacts with an extensive surficial aquifer and serves as a regional ground water sink. Ground water inflows to the Chehalis River are estimated using readily available existing information. Samples from 28 wells in the study area show that ground water quality is highly variable. The water quality results are presented in this memorandum. Chloride and organic loading via ground water is highest along the reach between river miles 72 to 77.5. (Also see abstract below) | |

| Abstract | Long Description |
The Chehalis River between the Thurston/Lewis County border (River Mile 60) and Adna (River Mile 86) hydraulically interacts with an extensive surficial aquifer and serves as a regional ground water sink. Ground water inflows to the Chehalis River are estimated using readily available existing information. Minimum and maximum ground water inflows range from 0.1 to 10.3 cubic feet per second per mile (cfs/mi). Estimated mean ground water inflows for six subaquifers range from 0.5 to 4.5 cfs/mi. Samples from 28 wells in the study area show that ground water quality is highly variable. The water quality results are presented in this memorandum. Chloride and organic loading via ground water is highest along the reach between river miles 72 to 77.5. |
