The Great Saint Patrick's Day Flood

The Great Saint Patrick's Day Flood is a novella for children by the American writer Mildred S. Flaherty based on events of the Pittsburgh Flood of 1936 in Pittsburgh, Pennsylvania.

Set in March, the Allegheny, Monongahela, and Ohio Rivers are rising. Eleven-year-old Billy Flynn and his seven-year-old brother Tommy are happy when school is cancelled. The boys' excitement soon turns to fear and awe as the rivers overflow their banks and people are forced to flee from their homes and work. Soon they experience life as they've never known it, discovering real courage and honor along the way.
