It is approximately 4.8 miles (7.7 km) long and flows through Conyngham Township in Columbia County and Mount Carmel Township in Northumberland County.^[1] The watershed of the creek has an area of 5.73 square miles (14.8 km²). The entirety of the creek is designated as an impaired waterbody due to metals from abandoned mine drainage. It is acidic, but its pH has been increasing. Underground mine complexes occur within the watershed. The creek has a permeable streambed and experiences flow loss.

A colliery historically discharged waste water into North Branch Shamokin Creek. A number of bridges have been constructed over the creek. Its drainage basin is designated as a Coldwater Fishery and a Migratory Fishery. However, the creek is incapable of supporting aquatic life, including fish and macroinvertebrates.
