The 1936 Northeastern United States flood was a historic flood that occurred across the Northeastern United States, as well as the Mid-Atlantic region and Ohio, in March 1936. Record-setting flooding after a combination of a particularly precipitation-heavy winter and large amounts of rainfall in March caused severe damage across the region. Record heights were recorded in many rivers, including the Connecticut River, which peaked at 37.6 feet (11.5 m) in Hartford, the Merrimack River, the Pemigewasset River, and the Androscoggin River.
