Statement: Reservoir emplacement in the USA since 1800
Abstract: This movie shows the creation of dams throughout the continental US through time. It is a geographic information systems (GIS) based map where each dam is shown in its geographic location and appears on the map in the year of its construction. The progression of settlers west and the subsequent need for water for irrigation can be seen, as can the sudden increase in dam creation as part of The New Deal economic stimulus program for hydroelectric power and flood control needs.
Large and small dam emplacement in the USA. Data shown from the National Inventory of Dams (NID).
