Colorado River Basin Focus Area Study
U.S. Geological Survey National Water Census: Colorado River Basin Geographic Focus Area Study
WaterSMART—The Colorado River Basin Focus-Area Study
The Focus Area Study developed estimates of evapotranspiration for the Colorado River Basin at regional and field scales using remotely-sensed resources and ground-based verification measurements to inform Water Availability Studies and Water Use Assessments.
