This dataset contains annual Rio Grande Project surface-water allotments and diversion allocations from 1940 through 2014 to lands within New Mexico, Texas, and Mexico. Allotment and allocation values were extracted from the Allocation spreadsheet (Ferguson, I., Bureau of Reclamation, written commun., 2016). Allotment values are presented in units of acre-feet per acre. Allocation values are presented in units of acre-feet.

This dataset contains annual irrigated acreage for New Mexico and Texas from 1938 through 2010 for six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007). Irrigated acreage values were extracted from the New Mexico Office of the State Engineer’s (NMOSE’s) Canal spreadsheet, version 11.2 (Barroll, P., NMOSE, written commun., 2011).

This dataset contains the model-simulated area of seven canal service units in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). The total model-simulated area of each service unit is presented, as well as the area within each service unit with irrigation-water supplied by a combination of groundwater and surface-water and by only groundwater. Area values are presented in units of acres. The equivalent canal service unit used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007) is also indicated for each RGTIHM service unit (see the Canal_Balance_Annual_Acreage tabular dataset).

This dataset contains the monthly surface-water diversion allotments from March 1940 through 2014 for the 57 water-balance subregions (WBS) within the seven canal service units simulated in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Allotment values are presented in units of acre-feet.

This dataset contains monthly crop irrigation requirement (CIR) values from 1938 through 2014 for six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007). CIR values from 1938 through 2010 were extracted from the New Mexico Office of the State Engineer’s (NMOSE’s) Canal spreadsheet, version 11.2 (Barroll, P., NMOSE, written commun., 2011). CIR values from 2011 through 2014 were copied from a year within the 1938 through 2010 dataset with a similar total annual precipitation as recorded at the State University, NM US station, part of the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC) Global Historical Climatology Network (GHCND) (NCDC, 2016a, b). CIR values are presented in units of acre-feet per acre.

This dataset contains annual agricultural groundwater pumping values in 1975 for Doña Ana County; in 1980, 1985, 1990, 1994, 1995, 2000, 2005, and 2010 for Doña Ana and Sierra Counties; and in 2009, 2011, 2012, 2013, and 2014 for the Lower Rio Grande Water Master District in New Mexico. Groundwater pumping values were extracted from Sorensen (1977), Sorensen (1982), Wilson (1986), Wilson (1992), Wilson and Lucero (1998), Wilson and others (2003), Longworth and others (2008), Stangl (2010), Longworth and others (2013), Serrano (2014), and Serrano (2015). Groundwater pumping values are presented in units of acre-feet.

This dataset contains monthly crop irrigation requirement (CIR) values from March 1940 through 2014 for the 20 virtual land-use units, including the seven canal service units, in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). CIR values are presented in units of feet per day.

This dataset contains monthly groundwater pumping values from 1938 through 2010 for areas within Elephant Butte Irrigation District (EBID) with irrigation-water supplied by only groundwater. Groundwater pumping values were extracted from the New Mexico Office of the State Engineer’s (NMOSE’s) Canal spreadsheet, version 11.2 (Barroll, P., NMOSE, written commun., 2011). Groundwater pumping values are presented in units of acre-feet.

This tabular dataset represents monthly flow at 61 surface-water points of diversion used to route flow in the Streamflow-Routing (SFR) Package for MODFLOW-One-Water Hydrologic Flow Model in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). Thirty-one of the 61 diversion points represent surface-water deliveries to combined groundwater and surface-water water balance subregions (WBS), and the remaining 30 diversion points represent diversions to canals and laterals along the surface-water conveyance network. Flow in this tabular dataset is specified monthly at each diversion point as either a rate (volume per time) in cubic feet per day, or as a fractional split from the simulated flow in the upstream segment. See the Div_ID attribute in the RGTIHM_SFR_Diversion_Pts and RGTIHM_SFR_Segments feature classes for the location of the points of diversion and the downstream segment to which the flow was routed, respectively.

This dataset contains the model-simulated area of 57 water-balance subregions (WBS) in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM) within the six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007), as well as the fraction of the area of each WBS with irrigation-water supplied by a combination of groundwater and surface-water relative to the total area within the service unit containing the WBS with irrigation-water supplied by a combination of groundwater and surface-water. Area values are presented in units of acres.
