Technical Abstract: Suitable dam and reservoir sites are scarce resources that should be sustainably developed to satisfy the needs of current and future generations. Historic and current dam development approaches do not address the issue of sustainable development (i.e., reservoir water storage is needed for both current and future generations). Estimated global net reservoir storage, after allowing for storage loss due to sedimentation, is either stagnating or declining despite continued dam construction worldwide. Average global storage loss due to reservoir sedimentation is estimated to be on the order of 0.8% or 1% per year. Globally, the per capita reservoir storage has been in decline since about 1980, with current per capita storage on the same order as it last was in the late 1950’s.
