• Title: RGDSS - Rio Grande Historic Crop Consumptive Use Analysis
• Description: The documentation is for the Rio Grande Basin Historic Crop Consumptive Use Analysis, developed during the RGDSS implementation for the period 1950 through 2002. It includes 100 percent of the crop consumptive use in the basin for the period. Documentation consists of the final Historic Crop Consumptive Use Analysis Report and supporting appendices.

climate stations was determined from the GIS coverages. This information is
summarized in Table 2.
6. Based on centroid elevations, distance to climate stations, and engineering judgement,
climate stations and a corresponding appropriate weight were assigned to each
County/HUC combination. The results of this analysis are presented in Table 3.
7. All nine climate stations included in the analyses have both temperature and
precipitation data. Therefore, the same weights were assigned to both temperature
and precipitation data.
8. The Water District Boundary GIS coverage was brought into the GIS project. Based
on the location of most irrigated acreage within water district, a default County/HUC
combination was assigned to the water districts as shown in Table 4.
