Water Monitoring

Water monitoring is the only method of knowing the exact water quality of the Swatara Creek. The Susquehanna River Basin Commission has a constant monitoring station installed at Swatara Watershed Park, 1929 Blacks Bridge Road, Annville, PA. Data from this station can be viewed at the following link.

In addition, citizen scientists sample and test water at the park monthly through the Alliance for Aquatic Resource Monitoring initiative through Dickinson College.

Historic Data:

Water Quality:  Over the years, due to its size, the Swatara Creek was impacted by a number of consumer and residential activities that contributed to an overall decline in water quality.   As a result, a fixed sampling station known as WQN 211 (0352030) was established at the mouth of the Swatara Creek to monitor basin quality on a monthly basis.
