Total existing area and projected area of primary waterbird habitat in the Central Valley of California for 17 climate, urbanization, and water management scenarios The dataset summarizes total area (km2) and proportion of Central Valley waterbird habitat, summed across individual waterbird habitats (i.e., wetland and cropland types), that was available for each of 17 projected scenarios. The dataset also includes relatively recent (year 2005) area of existing habitat (i.e., “existing area”) for comparison with areas based on scenarios. Analysis was conducted for the projection period including water-years 2006–2099 (water-year defined as October-December and January–September of the following year). Because habitat areas vary through the season with timing of crop harvest and flooding of wetlands and post-harvested fields, annual areas and proportions represent summation...

It is essential to include the managed component (i.e., the “human” component) to close the water budget and reduce the magnitude of the residuals from “natural” water budgets.

These areas of emergent marsh include: 1) marshes managed by federal (particularly the U.S. Fish and Wildlife Service’s Sonny Bono Salton Sea National Wildlife Refuge (SBSSNWR), state (California Department of Fish and Wildlife), and local (Imperial Irrigation District) resource agencies that are sustained by direct deliveries of Colorado River water; and 2) unmanaged marshes sustained by agricultural drainage water.

In addition, the resulting impact on flows in the Carson River and Lahontan Reservoir are also evaluated. During the economic boom that occurred from 2004-2006 in northwestern Nevada, municipal and housing growth increased stress on the limited water resources of this semi-arid region. In 2008, when the economy slowed, new housing development stopped, and immediate pressure on finite groundwater resources abated. In anticipation of economic recovery and resumed growth, however, the U.S. Geological Survey...

The dataset also includes relatively recent (year 2005) area of existing habitat (i.e., “existing area”) for comparison with habitat areas based on scenarios. Cropland habitats are defined as winter-flooded rice, unplowed dry rice, winter-flooded corn, unplowed dry corn, and other winter-flooded cropland (in Tulare basin). Wetlands are defined as summer-irrigated seasonal wetland, seasonal wetland that is not summer-irrigated, and semipermanent wetland (combines semipermanent and permanent wetland types).

In cooperation with the Bureau of Reclamation, the U.S. Geological Survey completed a study to develop multiple linear regression models to estimate salinity and selenium loads. The objective of the study was to refine existing models by improving the regressions and using additional geospatial and water-quality data. This data release presents the basin characteristics and loads used to calibrate the models. Also provided are salinity and selenium yield rasters determined by empirical Bayesian kriging of loads estimated by the...

Like many other mediterranean-climate ecosystems across the globe, the Central Valley has been subject to a burgeoning human population and expansion and intensification of agricultural and urban development that have impacted wildlife habitats. Future effects of urban development, changes in water supply management, and precipitation and air temperature related to global climate change on area of waterbird habitat in the Central Valley are uncertain, yet potentially substantial. Therefore, we modeled area...
