On April 24, 1980 the Waterford Historic District was entered into the National Register of Historic Places at the local level of significance. The district, located on the shores of Keoka Lake in southern Oxford County, is comprised of a discreet cluster of residential, commercial and civic buildings erected between 1797 and 1939, with the majority of the buildings dating to the 19th century. Essentially encompassing the nucleated village of Waterford Flat, the district recognized the twenty seven properties for their architectural significance under Criterion C. In addition, one property, a former hydropathic spa and inn, achieved significance for its association with social/humanitarian history, and another house gained significance in the realm of literature as the boyhood home of Charles Farrar Brown, better known as Artemus Ward. However one significant residential building on the north side of the district was omitted in error. Built in approximately 1860, the Italianate style Wilkins/Stone Home harmonizes architecturally with the existing district; it also compliments the existing village structures with regard to expanding the understanding of industry and tourism in Waterford. The property housed a tannery during the last four decades of the 19th century, and starting in about 1906-07 the property evolved from a single family home to a boarding house catering to summer visitors to the village. The purpose of the newly listed Waterford Historic District Boundary Increase was to expand the physical boundaries of the district to include the Wilkins House/Stone Home, and to also introduce Industry as an area of significance under Criterion D.
