Results from a new study shows a detailed map of ground water in eastern Jefferson County, documenting for the first time where water is exchanged between aquifers and streams in that area, according to a report published by the USGS.
In cooperation with Jefferson County Natural Resources Division, the USGS studied the ground water system in Chimacum Creek Basin. Scientists also investigated how water flows between aquifers and Chimacum and Tarboo Creeks and Big and Little Quilcene Rivers.
"We now have a more detailed picture of the ground water system in the watershed," said USGS hydrologist Bill Simonds, lead author of the report. "Because we have a better idea of where the ground water is and how it moves, resource managers can identify areas where ground water development might impact streamflow. They can also use this information to look for additional ground water as the county’s population grows."
Scientists measured water levels in 110 area wells and used well drillers’ reports, geologic maps, and LIDAR (airborne laser) imagery to develop a map of the geologic units near the surface of the Chimacum Creek Basin. Scientists also used hydraulic measurements and streambed temperatures to determine how water flows between ground water and streams in the basin.
The USGS report is now available on the Web at http://pubs.water.usgs.gov/sir2004-5058/. Simonds will explain the results of the study at a public meeting May 25, 7:00 to 9:00 p.m., at the Chimacum High School auditorium. For more information about the meeting, contact Dave Christensen, Jefferson County Natural Resources Division, at 360-385-9418.
