>The notch in Connecticut's northern border, just above Granby, is sometimes called the "Southwick Jog".>Following the Revolutionary War, in 1793, both states appointed Boundary Commissioners to run a straight boundary from Union, Connecticut to the New York state line. In 1797 the Commissioners recommended that a disputed 2.5 square mile tract be awarded to Massachusetts as compensation for its earlier losses of Suffield, Woodstock, Somers, and Enfield to Connecticut. However, it was not until 1804 that Connecticut agreed to yet another compromise that partitioned the 2.5 mile area at Congamond Lakes with Massachusetts receiving 5/8 of the disputed parcel along the west shore and Connecticut receiving the remainder, along the east shore.https://libguides.ctstatelibrary.org/hg/maps/jog
