Hurricane Diane - Aftermath

Aftermath

The flooding in the Delaware River water basin initiated federal involvement to dam the Delaware River with the Tocks Island Dam Project. The project fell through after opposition from local residents, lack of funding, and geological problems.

In Connecticut, flooding from Diane prompted the United States Army Corps of Engineers to build $70 million worth of dams and flood walls along several Connecticut Rivers. In 1960, they built the Thomaston Dam. In 1965, the Northfield Brook Dam, in 1968, the Hop Brook Dam and in 1969, the Colebrook Dam.

Hurricane Diane also severely damaged portions of the Delaware, Lackawanna and Western Railroad (DL&W), causing the railway to suspend operations for a period. The resulting debts and operational constraints placed upon the DL&W contributed to its ultimate merger with the Erie Railroad in 1960. Darlington's Bridge at Delaware Station was destroyed and never rebuilt.
