The restrooms at Bushkill Access go under up to the skylights in 2006.
In 2004, 2005, and 2006 three "100-year" floods hit the park. Archeological sites were inundated, streams leapt out of their banks to find new courses, roads were undercut, and some riverbank sites were scraped off the map. Each flood registered third highest in recorded valley history, but was then ousted from its position by the next flood.
Photos of the damage now spread easily about through digital images on the web. The three floods, and their picture galleries, became known in the park as "Ivan the Terrible" (2004), "The Spring Flood" (2005), and, fittingly, "Strike Three" (2006).
