Footnote 9
In 1936 Congress passed the Copeland Omnibus Flood Control Act, which had a provision to build that series of nine reservoirs along the upper portion of the Allegany Valley and made the Army Corps of Engineers (U.S.A.C.E) the U.S. federal government's official contractors of public work project. In 1938 the other nine reservoirs allocated in the Copeland Act began construction. The Kinzua Dam, which was part of the original series of nine, until our Seneca people voiced our opposition, stalling its construction until World War II forced the U.S.A.C.E to postpone its construction permanently.
After WWII, Pittsburgh big business revived the original plan involving a series of nine reservoirs, which at this point only had one reservoir left: the Allegany Reservoir created from Kinzua Dam.
