Watson Township is and always has been a largely unpopulated area. It is mountainous and covered with a thriving second growth forest. During the late 1800s much of the land was stripped of its virgin forests. At the time central Pennsylvania, and the city of Williamsport was the center of the lumber industry in the United States. Trees were cut down and floated down Pine Creek, which flows through Watson Township. There were several sawmills along Pine Creek in the township. Other early attempts at industry included an iron forge. There were several deposits of iron ore in Watson Township. The ore proved to be of low quality and the investors in the iron furnaces struggled to turn a profit. The furnaces were abandoned and little evidence of their existence remains.
