The area of Carbon County, Pennsylvania that is present-day Lehigh Township was considered to be part of Lausanne Township from 1808 until 1875. It was during that year that it became known as Lehigh Township.
In 1808, a tract of forested land near the Lehigh River was owned by members of the Moravian Church. In 1824, Lehigh Coal & Navigation Company executives purchased the lumber rights to that land and built four sawmills, housing for its workers and a town store on the land in order to establish a lumber harvesting operation to support the company's coal barge construction efforts. That first town was known as Lowrytown; it would later be known as Rockport.
