Report Availability


Water resources data for the 2005 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage and contents of lakes; and water levels and water quality of ground water. This report contains stage and discharge records for 77 stations, stage records for 92 stations, water-quality records for 54 surface-water stations and 137 wells, and water-level records for 277 wells. Also included are data for 158 crest-stage and flood-profile partial-record stations and additional water data were collected at miscellaneous sites. 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.


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, J. Josh Gilbert, Cheryl R. Joseph, Benton D. McGee, Garron B. Ross, Stanley C. Skrobialowski, Dan J. Tomaszewski, 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, 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, Water Science Center Director, Louisiana.
