Dams
on the
Connecticut River
|
Dams large and small impound much of the upper
river. Added together, the impoundments make up the
second largest lake in New Hampshire. Here is a
list of the 13 intact and 2 breached dams on the
upper river's mainstem, from north to south. Those
marked with an asterisk produce
hydroelectricity.

Flood Control
Dams
|
The U.S.
Army Corps of Engineers maintains a
series of flood control dams on several of
the river's major tributaries in NH and
VT. Construction of these dams was
authorized by Congress in 1936 to protect
downstream cities in the river's
floodplain, following a major flood in
that year.

Mainstem Dams

TransCanada, which currently owns and
operates the major mainstem hydro dams on
the upper river, provides information on
current
and projected flows at these dams.
