Quoddy Dam Museum
The Quoddy Dam Model Museum houses a working scale model of the
Passamaquoddy Bay Tidal Power Project which was built for the original project.
The model, formed of concrete and weighing thousands of pounds, shows the
locations of the proposed dikes and gates, as well as the turbine-powered
generating station. When operating, you can observe how the tides flow into the
area's bays, and how these tides could have been harnessed to generate
electricity.

Passamaquoddy Bay is an inlet of the Bay of Fundy, between the U.S.
state of Maine and the Canadian province of New Brunswick, at the
mouth of the St. Croix River. Most of the bay lies within Canada, with
its western shore bounded by Washington County, Maine. The
southernmost point is formed by West Quoddy Head on the U.S.
mainland in Lubec, Maine; and is then bounded northeastwardly by
Campobello Island, New Brunswick and Deer Island, New Brunswick;
thence, running to shores by mainland Charlotte County, New
Brunswick.

The Passamaquoddy Tidal Power Project/"Quoddy Dam" Project

A proposed development project for eastern Maine, envisioned by
hydroelectric engineer Dexter Cooper, involving the construction of a
tidal harness for electricity generation was initiated in 1935 under U.S.
Public Works Administration funding and with the blessing of President
Franklin Delano Roosevelt, whose summer home was on nearby
Campobello Island, New Brunswick, Canada.

Also known as the Quoddy Project, it proposed impounding Cobscook
Bay and part of Passamaquoddy Bay with a series of dams and
control structures to exploit the resulting water level difference to
generate electrical power. The electric turbines for power generation
would have been located at the isthmus on Moose Island, Eastport,
with the water passing between Passamaquoddy Bay and Cobscook
Bay, with the "used" generating water released from impoundment at
low tide.

Part of this project was completed by the construction of dikes built
between Pleasant Point-Carlow Island-Moose Island. The project was
suspended one year later after the United States Congress refused
further funding, thus the actual barrier dams never being built. The
dike barriers now underlie the former Maine Central Railroad and the
current Maine Highway 190, as well as between Treat Island (in
Eastport) and Dudley Island (in Lubec, Maine).

Several iterations and variations on the project later ensued, but
never began construction.
