Matthew 7:27

Some know them as levees and others call them dikes, but the large embankments along the river were not always here. The oldest and most extensively used method of flood control, levees keep raging floodwaters from racing through people's homes and businesses. To make a levee, tons of earth and other fill material are placed and compacted to form a watertight earthen dam. Grass sod planted on the slopes prevents the soil from washing away. In sections where the river current may cause erosion, the sloping river side of the levee is armored or protected with a layer of stone called riprap.

Building levees is a science. Designing a successful levee means taking into account the river's path, foundation conditions, the kind of materials used to construct the levee embankment and armoring, if needed. Levees differ in height depending upon the severity of local flooding, costs, environmental impacts and other factors. The US Army Corps of Engineers, Baltimore District, built the first levees along the Susquehanna River in the late 1930s, following the Wyoming Valley's devastating 1936 flood. Tropical Storm Agnes in 1972 led the Corps to enlarge them and add
