The study will: 1) improve the integration of state water-use and water supply data; 2) develop a basin-wide surface-water hydrologic model capable of evaluating the impacts of land-use change, climate change, and changes in water demand; and 3) develop a scientific approach to defining relations between streamflow processes and the responses of aquatic organisms in tributary streams.
The spatial extents of verified irrigated lands were compiled from various federal and state sources across the nation and combined into a single Geographic Information System (GIS) geodatabase for the purpose of model training and validation. In cooperation with U.S. Geological Survey (USGS), researchers at the University of Wisconsin (UW) generated a nation-wide map of irrigated lands using remote-sensing techniques that will be incorporated into future irrigation water-use models. The verified spatial data varies in scope, accuracy, and time period represented, but in general represents GIS coverages (polygons) of agricultural land irrigated for at least some period during 2002–17. Data from 14 states were provided...

Consumptive use (CU) of water is an important factor for determining water availability and groundwater storage. Many regional stakeholders and water-supply managers in the Upper Rio Grande Basin have indicated CU is of primary concern in their water-management strategies, yet CU data is sparse for this area. This polygon feature class, which represents irrigated acres for 2015, is a geospatial component of the U.S. Geological Survey National Water Census Upper Rio Grande Basin (URGB) focus area study's effort to improve quantification of CU in parts of New Mexico, west Texas, and northern Chihuahua. These digital data accompany Ivahnenko, T.I., Flickinger, A.K., Galanter, A.E., Douglas-Mankin, K.R., Pedraza, D.E.,...

An existing biological response model of fish populations in the Tennessee and Apalachicola, Chattahoochee, Flint (ACF) River basins, and an existing biological response model of invertebrates in Delaware and NC will serve as the starting points for the development of empirical flow-biology response models for the Yadkin/Pee Dee/Waccamaw and Cape Fear River basins. The existing ecological response models will be used to determine if the land-use and streamflow characteristics that are important in determining biological responses in the existing models are also important in the Yadkin/Pee Dee/Waccamaw and Cape Fear River basins or whether other variables are more important in determining responses. These comparisons...

Actual ET (ETa) is produced using the operational Simplified Surface Energy Balance (SSEBop) model (Senay and others, 2013) for the period 2000 to present. The SSEBop setup is based on the Simplified Surface Energy Balance (SSEB) approach (Senay and others, 2007, 2011) with unique parameterization for operational applications. It combines ET fractions generated from remotely sensed MODIS thermal imagery, acquired every 8 days, with reference ET using a thermal index approach. The unique feature of the SSEBop parameterization is that it uses pre-defined, seasonally dynamic, boundary conditions that are unique to each pixel for the hot/dry and cold/wet reference points. This summary of the SSEBop ET dataset was created...
The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change. The heavy use of the available groundwater resources has resulted in substantial groundwater-level declines and reductions in baseflow in streams within the MAP. These impacts are limiting well production and threatening future water availability for the region. On average it is estimated that over 9 billion gallons per day of groundwater are withdrawn for irrigation, supporting agricultural production. Agricultural interests in the region are aware of the economic and environmental costs that may come...

Optimal hydrograph separation (OHS) is a two-component, hydrograph separation method that uses a two-parameter, recursive digital filter (RDF) constrained via chemical mass balance to estimate the base flow contribution to a stream or river (Rimmer and Hartman, 2014; Raffensperger et al., 2017). A recursive digital filter distinguishes between high-frequency and low-frequency discharge data within a hydrograph, where high-frequency data corresponds to quick flow or storms and low-frequency data corresponds to base flow. The two parameters within the RDF are alpha and beta, both are unitless. Alpha is defined as the recession constant and typically found through recession analysis. For the purposes of this data release...

Alluvial basin boundaries in the Upper Rio Grande Basin (URGB) were a needed dataset for the groundwater component of the URGB Focus Area Study (FAS). A literature and data search revealed not all of the alluvial fill basins existed in a digital format that could be imported and used in a Geographic Information System (GIS). Available resources such as georeferenced report figures, digital elevation models (DEMs), principal aquifer dataset, surficial geology, and structural features, such as faults, were used to aid in defining the alluvial basin boundaries. An Esri ArcGIS geodatabase was created to house the final digitized dataset of the following alluvial basins: San Luis, Espanola, Socorro, La Jencia, San Marcial,...

A major component of the Water Census is the National Water Census Data Platform, which enables integration and delivery of water budget information alongside other data of interest to managers, such as water use data or ecological assessment criteria. Eventually, end users of water budget data (i.e. management agencies and decision-makers) will be able to access an integrated system of online databases in a form that will enable them to construct local and regional water budgets.

The Red River Basin of New Mexico, Oklahoma, Texas, Arkansas, and Louisiana was chosen as a focus area study (FAS) as part of the U.S. Geological Survey (USGS) National Water Census (NWC). The objective of the NWC is to place technical information and tools in the hands of stakeholders so that they can make decisions on water availability. With this set objective, the USGS Water Science Centers in New Mexico, Oklahoma, Texas, Arkansas, and Louisiana conducted a study of water use and availability for the Red River Basin to improve water withdrawal estimates and investigate trends in water resources under future climate conditions and increased water withdrawals using groundwater and surface-water models (MODFLOW...

The Water Availability Tool for Environmental Resources (WATER) is a decision support system (DSS) for the nontidal part of the Delaware River Basin (DRB) that provides a consistent and objective method of simulating streamflow under historical, forecasted, and managed conditions. WATER integrates geospatial sampling of landscape characteristics, including topographic and soil properties, with a regionally calibrated hillslope-hydrology model, an impervious-surface model, and hydroclimatic models that have been parameterized using three hydrologic response units—forested, agricultural, and developed land cover. It is this integration that enables the regional hydrologic-modeling approach used in WATER without requiring...

Integrated land- and water-use planning strategies are gaining attention as means to inform consideration of more water-efficient urbanization patterns in response to uncertain water availability. We coupled climate and land change projections with empirically-derived coefficient estimates of development-related water demand to project water demand under future conditions of environmental change. Development-related water demand, used to characterize the water footprint of urbanization, is classified as the combined use of public water supply, domestic self-supply and industrial self-supply. We simulated two scenarios of urban growth from 2012 to 2065 using the FUTure Urban-Regional Environment Simulation (FUTURES)...

In 2014, the Upper Rio Grande Basin (URGB) of Colorado, New Mexico, Texas, and northern Mexico was chosen as a focus area study (FAS) for the U.S. Geological Survey (USGS) National Water Census. The three main objectives of the USGS National Water Census are to (1) provide a nationally consistent set of indicators that reflect each status and trend relating to the availablity of water resources in the United States, (2) provide information and tools that allow users to better understand the flow requirements for ecological purposes, and (3) report on areas of significant competition over water resources and the factors that have led to the competition. The URGB FAS will help meet these objectives through an integrated,...
