Estimated Use of Water in the United States
Hydrologic Unit Data for 2005

These data files present water-use estimates by hydrologic unit for selected States. Most of these estimates were prepared for the States in the Great Lakes Basin (Hydrologic Region 04) and support the water-use estimates published in Estimated withdrawals and other elements of water use in the Great Lakes Basin of the United States in 2005 (USGS Scientific Investigations Report 2010–5031).

Comprehensiveness of data collection for the Great Lakes Basin (all or part of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin)

• All States provided estimates for public supply, domestic, irrigation, livestock, aquaculture, industrial, mining, and thermoelectric power water use for the hydrologic cataloging units (HUC-8) in the Great Lakes Basin. All States also provided estimates of public supply deliveries for domestic use and wastewater reuse for those HUCs.
• All States estimated the total population served by public supply. States optionally may have estimated public supply population served by groundwater and surface water.
• All States have estimates of total irrigation. States optionally may have estimated subtotals for crop irrigation and golf-course irrigation.
• Commercial water-use data were estimated for Illinois, Indiana, Minnesota, Ohio, and Wisconsin for 2005.
• No wastewater release data were obtained for 2005. (See a discussion in SIR 2010-5031.)
• No hydroelectric power instream use data were collected for 2005.
• Public-supply deliveries for commercial, industrial, and thermoelectric power were not collected for 2005.

Levels of data aggregation and release outlet

• Hydrologic cataloging unit (HUC-8) data for the categories listed were published for 2005 in USGS Scientific Investigations Report 2010–5031 and can be downloaded from this page.
• No water-use estimates were compiled nationally by water-resources cataloging unit for 2005 other than for the Great Lakes Basin, although other States also may have estimates by water-resources cataloging unit. The USGS State Water-Use Information Contact may be able to provide additional information.
• Water-use estimates also were compiled by county for 2005.
• No water-use estimates were compiled nationally by aquifer for 2005.

Data Files

HUC data files are linked in the table below. Data files are provided in Microsoft Excel 2003 format (.xls). (The use of trade names is for identification purposes only and does not constitute endorsement by the U.S. Geological Survey.) Microsoft has a free viewer program for Microsoft Excel files for those who do not own a copy of Microsoft Excel.

Data dictionary information is provided in Excel comment fields attached to each column heading and to cells containing HUC codes. Separate data dictionaries in PDF format also are available for Appendix 1B and Appendix 1C. (Adobe Reader or similar software is required to view this PDF file. Download the latest version of Adobe Reader, free of charge.) A separate listing of HUC codes and names is available. In these files, NA means not applicable; NR means not reported; and NULL means value unknown, not reported.

Additional data files to support the report Estimated withdrawals and other elements of water use in the Great Lakes Basin of the United States in 2005 (USGS Scientific Investigations Report 2010–5031):
Files for Appendix 1B, by State are those presented above with the exception of New York. A preliminary data file for New York was used for SIR 2010-5031 and was later revised to be consistent with the final county data used in USGS Circular 1344, Estimated Use of Water in the United States in 2005. The consolidated table presented in Appendix 1C also used the preliminary data for New York. Water-use estimates based in part or whole on the preliminary values are identified by bold typeface in the linked files below.
