Springton Dam is owned and operated by AQUA Pennsylvania Inc.
The reservoir is part of the drinking water supply network serving the Philadelphia area.
A flood reassessment revealed that the spillway and the return channel were incapable of discharging the revised design flood.
The dam owner decided to lower the spillway crest, while maintaining the top of the crest at its original level by installing fusegates, and to enlarge the spillway channel.
