A vast majority of dams are small, locally or privately owned, built initially to control water flow, mill grain, transport lumber, or create a reliable fishing spot. Thousands of these dams have begun to degrade inside our rivers, posing a significant threat to aquatic, terrestrial, and human life. The average dam in the US is 57 years old. While dams were built with the best construction and engineering standards of the time, many are not expected to withstand current extreme weather predictions that come with climate change-extreme storms, large floods, and earthquakes (in some areas). Massachusetts alone has over 3,000 dams, and most of them are obsolete and unsafe. |
