Maxwell and his assistants started a preliminary survey on June 13, 1788 from the 82-mile stone on the Pennsylvania Line. The trial survey reached Seneca Lake. The actual survey was started on July 25, 1788, and when the surveyors reached the area of Kandesaga, the line was fixed west of Seneca Lake and Kandesaga, which survived as a key town in the region. Oliver Phelps was extremely upset when he learned that the survey did not include Seneca Lake or the Indian village. He wrote a letter to Col. William Walker, the local agent responsible for the survey, and requested that they survey be redone in that area. For unknown reasons, it was not completed.
