"Invasion of the Iroquois". In 1986, Iroquois Gas Transmission System sought permission from the Federal Energy Regulatory Commission to construct a natural gas pipeline through New York and Connecticut. The proposed route ran through Lake Waramaug's eastern watershed, across the Shepaug River, and through the Steep Rock Reservation, with a secondary spur running through Washington Green and Nettleton Hollow. The Washington Environmental Council became an intervenor in the proceedings, retained a prominent Washington, D.C., law firm, and mounted a vigorous opposition campaign. In 1989, Iroquois decided to reroute the pipeline, shifting it south of Washington's borders.
