In 1877 Omaha's Carter Lake was formed by a massive flood which altered the course of the Missouri River. The Great Flood of 1881 filled the Omaha and Council Bluffs with water for almost a month, causing two fatalities and millions of dollars in damage. As many as 1,000 people were displaced by a flood in 1943, which sent the Missouri River, Carter Lake, and the old Florence Lake into peoples' homes and businesses throughout East Omaha. The flood of April 13, 1952 led to 40,000 people being evacuated from East Omaha and Carter Lake. President Harry S. Truman personally visited the scene of the flooding in Omaha and officially declared it a disaster area.

Several neighborhoods in central Omaha and North Omaha were severely damaged by the Easter Sunday tornado of 1913, which destroyed many businesses and neighborhoods. More than 200 people died during the event. The Omaha Tornado of 1975 moved across 10 miles (16 km) of streets and residences, crossing the city's busiest intersection at 72nd & Dodge. Three people were killed and 133 reported injured. Over 4,000 buildings were damaged and 287 were destroyed. In terms of damage, it was the costliest tornado in American history to that date, with insurance costs estimated at up to $1.1 billion (in 1975 dollars).
