Tangascootack Creek is a tributary of the West Branch Susquehanna River in Clinton County, Pennsylvania in the United States. Tangascootack Creek stretches for 8.48mi through Bald Eagle, Beech Creek and Colebrook Townships. Its watershed covers 36.5 square miles. Among its tributaries are North Fork Tangascootack Creek and Muddy Run, and there is also a swamp called Bear Swamp near the headwaters. Coal mining, including strip mining, was common in the watershed throughout the 1800s and 1900s. The creek experiences acid mine drainage, much of which comes from Muddy Run.The watershed is mostly forest and sparsely populated. Historically, the area supports industry in agriculture, lumbering, and coal and iron mining. Native American crucibles have been discovered along the Creek.Minerals in the watershed are mostly bituminous coal, fireclay, sandstone and slate. The daily loads of aluminum and manganese are both many times higher than the creek's total maximum daily load. The conductance of the creek ranges from 93.7 to 549 micro-siemens per centimeter. The creek is one of the most downstream tributaries of the West Branch Susquehanna River contributing acid mine drainage to it.
