As noted in a previous column, The National Weather Service Forecast Center’s Mississippi River Flood History posted a timely item. In 1543, Hernando De Soto experienced a 40-day flood near what is now Memphis. In 1788, a hurricane caused severe flooding, which also marked the arrival of Acadian exiles at Fort Bute, Manchac and Baton Rouge. Another spring-flooding episode occurred in 1825, known as the last inundation of New Orleans on the lower Mississippi River. During the greatest flood in history, Secretary of Commerce Herbert Hoover was elected president and enacted legislation to implement flood control projects. One year later, work on the Bonnet Carré Spillway began, with a capacity flow to match Niagara Falls. Fastcast: Nice.
