The 1979 Easter flood was among the most costly and devastating floods ever to occur in Mississippi, with $500-700 million in damages. This is equivalent to $1.65 billion in present-day terms. It was the result of the Pearl River being overwhelmed by severe rain upstream. Floodwaters sent the Pearl 15 feet above flood stage. More than 17,000 residents of Jackson, Flowood, Pearl, Richland and other communities were forced from their homes. The flooding of the Pearl River placed most of Jackson, the state's capital city, under water.

The river
The Pearl River is 490 miles long. It begins in Winston County, Mississippi and ends at the Mississippi Sound. Northeast of Jackson, the man-made Ross Barnett Reservoir is formed by a dam in the Pearl River. It flooded due to abnormally high rainfall in the preceding months (up to 150% more than usual). The water level reached a record-setting 43.28 feet on April 17, 1979.
