For More Colorado River Basin Water According to scientists at the Rocky Mountain Experiment Station, the annual flow of the Colorado River could be increased up to 6 million acre-feet if all contributing forest and brush lands were managed solely to increase water yields. Such dramatic increases could not be achieved without serious impact to other forest resources including economic, social, and environmental values. Such resources need to be considered. Water yields in the upper Colorado River Basin could be increased an estimated 500,000 acre-feet by appropriate management of one-fifth of each major vegetation type. Half that increase would come from subalpine forests, where well-designed timber harvests would create small forest openings to trap blowing snow. More extensive treatments would be necessary to get an additional 250,000 acre-feet in the lower Basin. Ninety percent of the increase would be generated by creating a mosaic of grassy openings in one-fifth of the chaparral and by intensive management of a third of the ponderosa pine. This type of management could also substantially increase yields of timber and forage for livestock, as well as improve landscape aesthetics, recreation opportunities, and habitat for many species of game and nongame wildUfe.
