Certainly worth monitoring. The two largest losses of life in Pennsylvania due to dam failures occurred over a century ago. Most people have probably heard of the Johnstown flood caused by the failure of the dam upstream from that city. David McCollough wrote an excellent book on that disaster. The next-biggest, upstream of Austin, PA was the result of a paper mill's dam failure and killed 78 people (more details here: https://w.wiki/HJBV). Remnants of that dam remain to this day in a park-like setting.
