Executive Summary This study was authorized by the Colorado Water Conservation Board (CWCB) under Section 37-60-106 (1) (c) of the Colorado Revised Statutes. Under this statute, the CWCB has the power and duty "to devise and formulate methods, means and plans for bringing about the greater utilization of the waters of the state and the prevention of flood damages therefrom." The purpose of this study is to summarize specific flood events that occurred throughout Colorado during 2001 by conducting interviews and performing other data collection tasks, performing data analysis, and summarizing this information in a report. The CWCB initially identified a number of individual flood events during the flood season, July through September of 2001. The identified events are located along the Front Range, in the eastern plains, and in western Colorado. Figure ES-1 shows the identified areas included in this study, and Table ES-1lists the reported dates and type of storms.
