Abstract
The evaluation of long-term drought variability was investigated for the Colorado River basin using instrumental and reconstructed streamflow data. Streamflow data was reconstructed for the past 500 years in the Colorado River Basin using Partial Least Squares Regression (PLSR). The occurrence of past drought events is also presented for 17 streamflow stations in the basin. Results indicated that the 1500's through the 1800's had more droughts than the 1900's. In addition, the worst drought years were in the late 1500's.
