Kreitler, J., and Lowe, S.E., 2019, Projections of Future Water Demand for the Western USA: U.S. Geological Survey data release,


This data release contains projections of future water demand for the Western USA at the county level. This data is part of the project "Changes to Watershed Vulnerability under Future Climates, Fire Regimes, and Population Pressures" (, and is the product of an analysis that determined where populations are changing, and how that change could affect residential and agricultural water withdraws from surface and ground water. Agricultural water use was derived from the Cropland Data Layer (CDL) of the National Agricultural Statistics Service, while residential water use was drawn from the USGS (Maupin et al. 2014). The scenarios follow four Intergovernmental Panel on [...]

The modeling in this task is the result of the integration of three different datasets: 1) housing density and population changes, 2) land use changes, and 3) observed water-use intensities and sources (ground vs. surface). The result of this integration is a dataset that presents the projected changes in agricultural and residential water demand under different climate change storylines and across different time horizons.
