Dams are man-made structures built across a watercourse to impound water and reduce the flow downstream.
Dams are often used to create retention/detention basins, reservoirs, and ponds. For each dam, the information in this section includes the type of dam (e.g., earthen, concrete, etc.), the name of the agency or organization that constructed the dam, the date of construction, the name of the agency or organization that maintains the dam, the purpose of the dam, and the historical performance of the dam.
This section includes key dimensions and elevations of the dam; width, height, top elevation, spillway crest elevation, normal pool elevation, and emergency spillway elevation. In addition, details on operation or emergency plans may be included in this section.
