In other areas, but to a lesser degree, regulation storage is also provided to store excess water in high runoff years for use in the drier years. Numerous irrigation reservoirs have been constructed in the re- gion, but more are needed to fully develop the irrigation potential. The lack of information precludes an analysis as to the amount of reservoir water actually used for irrigation during a specific year. Pine trees frame scenic view of one of several man-made lakes in the Upper Colorado Region to impound water for irriga- tion of downstream lands.
