In 1936, there was a big rainstorm in Pittsburgh that lasted for days. This caused the rivers in Pittsburgh to overflow and flood the city. When the water rose, it went into people's homes and businesses, destroying everything in its path. Many people had to leave their homes and go to higher ground to stay safe.
The flood was really bad because there were a lot of hills in Pittsburgh, and the water came down from the hills really fast, like a big river. People tried to stop the water with sandbags, but there was just too much water. People also tried to get around in boats, but it was too dangerous.
The flood lasted for a few days and when it was over, it left behind a lot of damage. The houses and buildings that were flooded had to be cleaned up and fixed. People also had to try to find their belongings that were lost in the water. It was a difficult time for the people of Pittsburgh, but they came together to help each other and work towards rebuilding their city.
