Sustaining benefits from small reservoirs: World Bank terms watershed management critical
Watershed management is critical to sustain the benefits from the development of small water storages or small dams in Barani Areas, said Asian Development Bank's experts. In a project review report on "Watershed Management Constraints in Barani Areas", Sedimentation Surveys of sample dams in the Pothowar region reveal that loss in water storage capacity can be as high as 4.2 percent per year, which could lead to full siltation of the dam's dead storage after 24 years.
