Flood Control

The Sunbury Flood Reduction System was designed and built by the US Army Corps of Engineers and completed in 1952. The System is a certified FEMA levee and provides protection on the Susquehanna River with 3+ feet of freeboard above the 100 year flood event of 556,000 cfs and provided protection of 620,000 cfs in 1972, which is about the maximum discharge the city will be protected against by utilizing the freeboard. A freeboard of 3 feet+ is also provided along Shamokin Creek against a discharge of 16,000 cfs occurring when the Susquehanna River is at 556,000 cfs.
