"Floods have continued to be a concern for Johnstown. Johnstown has experienced additional major flooding in subsequent years, including 1894, 1907, and 1924. The most significant flood of the first half of the 20th century was the St. Patrick's Day Flood of March 1936, which also reached Pittsburgh and became known as the Great Pittsburgh Flood of 1936.
More recently, on the night of July 19, 1977, a relentless storm reminiscent of 1889 bombarded the watershed above the city and the rivers began to rise. By dawn, the city was under water that reached as high as 8 feet (2.4 m). The seven counties disaster area suffered $200 million in property damage and 80 lost lives, 40 of which were caused by the Laurel Run Dam failure. Another 50,000 were rendered homeless as a result of the "100 year flood". Markers on one corner of City Hall at 401 Main Street show the height of the crests of the 1889, 1936, and 1977 floods."
