Forty years ago today, Hurricane Agnes moved from Pennsylvania into western New York, having wreaked havoc on much of the state. In Pittsburgh, the storm dumped 11 inches of rain during a three-day period.
Subsequent flooding pushed waters to 11 feet above flood stage on June 24, 1972, forcing Mayor Pete Flaherty to ask downtown business owners to secure their buildings and send their employees home.
Hit particularly hard was the Fort Pitt Museum, which was then administered by the state of Pennsylvania (today, it’s run by the Heinz History Center). Located near the confluence of Pittsburgh’s three rivers in Point State Park, the museum was under 4 feet of water during the flood.
According to a report later issued by the Pennsylvania Historical and Museum Commission, the site suffered an estimated $240,000 worth of damage. Fortunately, the museum’s curator was able to move most of the collection to a secure location in the hours preceding the flood.
