• 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.

CU from Surface Water - - CU from Ground Water
Figure 4 shows the annual estimated diversions from surface water and ground water to
meet crop irrigation requirements. The average annual surface water diversions from
1950 through 2002 were 1,077,400 acre-feet while the average annual ground water
diversions (pumping) were 542,945 acre-feet. Note that increases in pumping tend to
occur when surface water supplies are relatively low.
