The main contributors to the flow are precipitation and groundwater discharge. The creek is fed by various tributaries, including Manada Creek and Quittapahilla Creek. There are also several dams along the creek, including the DeHart Dam and the Hershey Dam.

Interestingly, the Swatara Creek was once heavily polluted due to industrial waste, but efforts to clean it up have led to improvements in water quality and increased fish populations.
