The initial establishment of Angle Township being in the United States was due to a map-maker's error. Benjamin Franklin and British representatives established the initial U.S. and Canadian borders in the Treaty of Paris in 1783 from a map that mis-represented the source of the Mississippi River. In 1997, in order to change what were considered unequal fishing regulations between the U.S. and Canada, Angle Township resident Gary Dietzler utilized this cartographical mishap to implement a mock secession from the United States, going so far as to get a bill issued by their Congressman Collin Peterson (D) in the U.S. House of Representatives. The mock secession succeeded in getting fishing regulations better synchronized across these international (fresh) waters.
