Preliminary Study of Watershed Management and Water Yields of the Upper Gila River
Excerpt from Preliminary Study of Watershed Management and Water Yields of the Upper Gila River
Soil erosion is an equally important upper Gila prob lem. Large areas of the watershed lands have been gullied and about acres of the irrigated valleys have been come pletoly lost. This destructive process continues to deplete the forage and agricultural productivity of the area and is affecting the regime of the river. Allied to the problem of erosion itself is that of reservoir sedimentation. Erosion products are accumulating in the San Carlos reservoir so rapid ly that its effective Operation may extend only about forty five years. An equally serious effect of sedimentation is that it causes increasing exposure of stored water with consequent high evaporation losses.
