Flood Waters Receding

According to the National Weather Service Advanced Hydrologic Prediction Service, at 10:30 a.m. on Wednesday, August 5 the Little Lehigh Creek had fallen below flood stage near Allentown at 4.34 feet.  Flood stage is 5 feet.  It fell below the 8 foot flood stage in Allentown at 5:00 a.m. Wednesday.

In terms of storm water volume, Tropical Storm Isaias exceeded a record set during 1972’s Hurricane Agnes. That storm pushed the Little Lehigh Creek near Allentown to record levels, a mark that was beaten Tuesday, when the Little Lehigh crested at 12.76 feet, considered major flood stage.

According to the National Weather Service, The Little Lehigh at Allentown’s 10th Street Bridge was at 12.2 feet at 6:00 p.m. on Tuesday, putting flooding into the major severity category.

At 11.0 feet portions of Little Lehigh Parkway pathways are damaged or destroyed.
