• 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.

2. Part of Archuleta County lies in the southwest corner of the Rio Grande Basin in
HUC 13020102. A small portion of Conejos County also lies in this HUC. The
runoff from these areas contributes to the Rio Chama, which flows into the Rio
Grande in New Mexico. The nearest climate station is in Chama, New Mexico. We
wanted to avoid using an out-of--state climate station, if possible, because we felt it
would be better if Colorado did not need to update information from another State in
HydroBase. There are currently no diversion structures or irrigated acreage identified
on the GIS coverages in these areas. Therefore, we felt justified in assigning 100
percent of the Colorado Manassa station to these areas for use if acreage is identified
in the future.
