Abstract

Water resources data for the 2004 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains records for water discharge at 77 gaging stations; stage only for 86 gaging stations and 7 lakes; water quality for 60 surface-water stations (including 42 gaging stations) and 112 wells; and water levels for 304 observation wells. Also included are data for 158 crest-stage and flood-profile partial-record stations. Additional water data were collected at various sites not included in the systematic data-collection program, and are published as miscellaneous measurements. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Louisiana.

Preface

This volume of the annual hydrologic data report of Louisiana 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.

This 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 typed, edited, and assembled the report. 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, most of the data were collected, computed, and processed by area field offices.

The following individuals supervised the collection, processing, and tabulation of the data:  George J. Arcement, Jr., Dennis K. Demcheck, Paul A. Ensminger, Cheryl R. Joseph, Benton D. McGee, Garron B. Ross, and David J. Walters.

The following individuals contributed to the collection, processing, and preparation of the data:  Arthur R. Adams, Mary L. Anderson, Todd Baumann, Van G. Bergeron, Jeffery A. Brantly, Sebastian R. Brazelton, Tonya D. Davis, Michael Descant, Troy A. Devillier, James R. Fountain, C. Paul  Frederick, Frank R. Glass, Burl B. Goree, J. Josh Gilbert, Kevin Grimsley, Brian Hilton, Darrelyn C. Hutson, Marlon Johnson, Calvin L. Jones, J. Scott Jones, Wendell M. Lovelace, Tammy B. McKaskle, Erroll P. Meche, Pamela A. Montgomery, Scott M. Perrien, J. Christine Resweber, David C. Sasser, Jr., Ronald C. Seanor, Cindy G. Sibley, Lane B. Simmons, William B. Snee, Jr., Glen T. Stevens, Stanley C. Skrobialowski, Dan J. Tomaszewski, J. Craig Waters, and Aub N. Ward.

This report was prepared in cooperation with the State of Louisiana and with other agencies under the general supervision of Charles R. Demas, District Chief, Louisiana.
