Prepared in cooperation with other agencies U.S. DEPARTMENT OF THE INTERIOR GALE A. NORTON, Secretary U.S. GEOLOGICAL SURVEY Charles G. Groat, Director For additional information: District Chief, Water Resources Division U.S. Geological Survey 10615 S.E. Cherry Blossom Drive Portland, Oregon 97216 See additional USGS information on water resources of Oregon at http://oregon.usgs.gov 2003 PREFACE The annual Oregon hydrologic data report is one of a series of annual reports that document hydrologic data gathered from the U.S. Geological Survey’s surface- and ground-water data-collection networks in each State, Puerto Rico, and the Trust Territories. These records of streamflow, ground-water levels, and quality of water provide the hydrologic information needed by State, local and Federal agencies, and the private sector for developing and managing our Nation’s land and water resources. The report is the culmination of a concerted effort by dedicated personnel of the U.S. Geological Survey who collected, compiled, analyzed, verified, and organized the data, and who edited and assembled the reports. In addition to the authors, who had primary responsibility for assuring that the information contained herein is accurate, complete, and adheres to Geological Survey policy and established guidelines, the following individuals contributed significantly to the collection, processing, and tabulation of the data: Rodger M.

ABSTRACT (Maximum 200 words) Water resources data for the 2002 water year for Oregon consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs and water levels of wells •Water discharge for 181 gaging stations on streams, canals and drains. •Discharge data for 55 partial-record or miscellaneous sites and water quality sampling sites. •Stage and (or) contents for 26 lakes and reservoirs. •Water quality data for 127 streams, canals, lakes and wells. •Water-quality for 2 atmospheric disposition stations. •11 Ground-water sites. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating States and Federal agencies in Oregon. 14. SUBJECT TERMS 15.
