Henson 2018 online document U.S. Geological Survey Open-File Report 2018–1091 https://doi.org/10.3133/ofr20181091 This dataset contains annual surface-water diversion allocations from 1940 through 2014 for the six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007). Allocation values were derived from annual Rio Grande Project surface-water diversion allocations to lands within New Mexico and Texas extracted from the Allocation spreadsheet (Ferguson, I., Bureau of Reclamation, written commun., 2016). Allocation values are presented in units of acre-feet. This dataset was used to derive monthly surface-water diversion allocations for the 57 water-balance subregions (WBS) within the seven canal service units simulated in the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM) (see the RGTIHM_Allotments_by_WBS tabular dataset).

No formal attribute accuracy tests were conducted No formal logical accuracy tests were conducted Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the dataset has either not been conducted, or is not applicable. A formal accuracy assessment of the vertical positional information in the dataset has either not been conducted, or is not applicable. Annual surface-water diversion allocations from 1940 through 2014 for the six canal service units used in the Lower Rio Grande Basin groundwater flow model (SSPA, 2007) were derived by scaling annual Rio Grande Project surface-water diversion allocations to lands within New Mexico and Texas (see the Allotments_and_Allocations tabular dataset) extracted from the Allocation spreadsheet (Ferguson, I., Bureau of Reclamation, written commun., 2016) by the fraction of the area within each service unit with irrigation-water supplied by a combination of groundwater and surface-water as simulated in the RGTIHM relative to the total RGTIHM-simulated area in New Mexico or Texas within each service unit with irrigation-water supplied by a combination of groundwater and surface-water.
