<p>This data release contains estimated water-use data for 2005 aggregated to the county and HUC8 levels in the United States. The included datasets are:</p> <p>"<a href = "https://pubs.usgs.gov/circ/1344/">Estimated Use of Water in the United States in 2005</a>" (USGS Circular 1344, Kenny and others, 2009). This publication includes water use estimates at the county and HUC8 levels for all of the United States.</p> <p>Revised county and revised HUC8 estimates of water use in the United States in 2005. These data are based on Kenny and others, 2009, but include revisions to estimates made after the original publication.</p> <p>"<a href = "https://pubs.usgs.gov/sir/2018/5049/sir20185049.pdf">Estimates of Water Use and Trends in the Colorado River Basin, Southwestern United States, 1985–2010</a>" (USGS Scientific Investigations Report 2018-5049, Maupin and others, 2018). This publication includes water use estimates at the HUC8 level, but includes only the area within the Colorado River Basin. Supporting data available in the companion <a href = "https://doi.org/10.5066/F7P84B5G">data release</a> (Ivahnenko and Maupin, 2018).</p> <p>The estimates are shown for the following water use categories: public supply, domestic, commercial, irrigation, thermoelectric power, industrial, mining, livestock, and aquaculture. Each estimate dataset includes an associated methods table that describes the method used for each estimate by water use category. Please visit the metadata.xml for more information.</p> <p>Note on the irrigation attributes: This dataset includes multiple irrigation attributes: irrigation undifferentiated (IR), crop irrigation (IC), golf course irrigation (IG) and total irrigation (IT). Datasets prior to 2000 only include IR. Other irrigation attributes are available in 2000 and later datasets after the USGS began providing estimates for both crop irrigation and golf course irrigation. The 2000 to 2015 datasets include either IR for each area (county, HUC, aquifer) or estimates for both crop irrigation (IC) and golf course irrigation (IG). The 2000-2015 datasets also include a total irrigation (IT) attribute that is either equal to IR, or is equal to the sum of IG and IC. Estimates of irrigation undifferentiated (IR) were generated for certain states or areas in the 2000-2015 datasets when the input data required to separate out crop irrigation from golf course irrigation were unavailable. Therefore, IR may or may not include golf course irrigation (IG).</p> <p>Note on irrigation methods: when data is given in a total irrigation (IT) column, there is no corresponding column in the methods. Since the value of IT is derived from the values of IR, IG, and IC, as described above, these columns may be consulted for methods information.</p> <p>Note on the population figures: 2005 county-level population served estimates were either made as a total population served by a public supply system, or as separate estimates for population served by a public supply system with a groundwater source and served by a public supply system with a surface water source. Counties will have either a single PS-TOPop value, or else separate PS-GWPop and PS-SWPop values. </p> <br>
