Ice jam floods form when river ice jams along with pinch points and sharp turns in rivers after breaking up during warm or rainy weather. The ice jam acts as a dam, backing water up into riverine communities. This episode investigates the science and impacts of these unusual floods through interviews near the Pennsylvania-New York-New Jersey tri-state. Guests include Tom Vicchiariello, Director of Emergency Management for Port Jervis, New York; Bill Clark, President of Matamoras-Westfall Historical Society; and George and Betty Reaggs, long-time residents of the area.
