The authors would like to thank the Illinois Department of Natural Resources–Office of Water Resources (IDNR-OWR) and the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) for their work in measuring the elevation of the set high-water marks. The authors also acknowledge the many personnel in the U.S. Geological Survey (USGS)–Illinois Water Science Center who took streamflow measurements during the flooding and identified and flagged the high-water marks after the floodwaters had subsided. The authors acknowledge Bonnie Stich of the USGS–Office of Communications and Publishing for her timely and thorough editorial review of the report, and Pamela Lombard, Gary Johnson, and Jon Hortness of the USGS for their timely and thorough review of technical aspects of this report. Lastly, the authors acknowledge Tom Over, Audrey Ishii, and Kelly Warner of the USGS for their guidance throughout this study.

Flood of September 13–16, 2008, in Northeastern Illinois By David J. Fazio and Jennifer B. Sharpe Abstract scientific, unbiased information about the Nation’s rivers and streams. To meet critical needs for real-time streamflow data Major flooding occurred in northeastern Illinois during during the September 2008 flood event, USGS personnel September 13–16, 2008, following extended storm activity. were mobilized to the areas of flooding in order to make Rainfall recorded at select Illinois State Water Survey (ISWS), direct streamflow measurements and maintain the operational National Weather Service (NWS), and U.S. Geological readiness of the streamgages (See Activities Log at http:// Survey (USGS) rain gages in northeastern Illinois, ranged il.water.usgs.gov/flooddata/viewNews.cgi?date=20080913). from 2.39 to 10.51 inches throughout a 51-hour period USGS personnel collected 48 streamflow measurements at during September 12–14, 2008. The rainfall resulted in 45 streamgages; 4 additional streamflow measurements
