New Hampshire Flood Risk Management Projects

The U.S. Army Corps of Engineers has constructed 13 flood damage reduction projects in New Hampshire that significantly reduce flooding and associated damages.

The seven Corps-built dams (including the two dams built at the Hopkinton-Everett Lakes project) protect wide regions of the state.  Costing an aggregate $39.9 million to construct, they offer the public a variety of recreational opportunities and enhancing the environment.

The Corps has also completed seven other flood damage reduction projects in New Hampshire at a cost of $3.7 million.  These works are more commonly referred to as local projection projects because they provide flood protection to specific communities rather than wide areas of a state.  Local protection projects are operated and maintained by the respective municipalities, except for the Israel River project in Lancaster, which is operated by the town but maintained by the Corps of Engineers.

The following items are arranged by the various types of flood risk management projects constructed by the Corps in New Hampshire and a brief history and description of each project.
