Through Drainage basin and Reservoir

The American Red Cross, led by Clara Barton and with 50 volunteers, undertook a major disaster relief effort. Support for victims came from all over the United States and 18 foreign countries. After the flood, survivors suffered a series of legal defeats in their attempts to recover damages from the dam's owners. This led in the 20th century to American Tort law allowing, in some circumstances, strict liability rather than fault-based liability.

The events have been commemorated nationally as well as locally. The Johnstown Flood National Memorial was established in 1964. The National Historic Landmark District of the South Fork Fishing and Hunting Club was established in 1986. Both are administered by the National Park Service.

History

The city of Johnstown, Pennsylvania was founded in 1800 by Swiss immigrant Joseph Johns (anglicized from "Schantz") where the Stonycreek and Little Conemaugh rivers joined to form the Conemaugh River. It began to prosper with the building of the Pennsylvania Main Line Canal in 1836.

Construction of the Pennsylvania Railroad and the Cambria Iron Works in the 1850s brought further industry to town, and eventually led to abandonment of the canal. By 1889, Johnstown's industries had attracted numerous Welsh and German immigrants to work. With a population of 30,000, it was a growing industrial community known for the quality of its steel.

The high, steep hills of the narrow Conemaugh Valley and the Allegheny Mountains to the east restricted development of Johnstown, keeping it close to the riverfront areas. The valley received large amounts of runoff from rain and snowfall. The area surrounding the city is prone to flooding due to its location on the rivers, whose upstream watersheds include an extensive drainage basin of the Allegheny plateau. Adding to these factors, slag from the iron furnaces of the steel mills was dumped along the river to create more land for building and narrowed the riverbed. Developers' artificial narrowing of the riverbed to maximize early industries left the city even more flood-prone.

Immediately downstream of Johnstown, the Conemaugh River is hemmed in by steep mountainsides for about 10 miles (16 km). A roadside plaque alongside Pennsylvania Route 56, which follows this river, proclaims that this stretch of valley is the deepest river gorge in North America east of the Rocky Mountains.

South Fork Dam and Lake Conemaugh

High above the city, the Commonwealth of Pennsylvania built the earthenwork South Fork Dam between 1838 and 1853 as part of a cross-state canal system, the Main Line of Public Works. Johnstown was the eastern terminus of the Western Division Canal, supplied with water by Lake Conemaugh, the reservoir behind the dam.

As railroads superseded canal barge transport, the Commonwealth abandoned the canal and sold it to the Pennsylvania Railroad. The dam and lake were part of the purchase, and the railroad sold them to private interests.

Henry Clay Frick led a group of Pittsburgh speculators, including Benjamin Ruff, to purchase the abandoned reservoir, modify it, and convert it into a private resort lake as a property for their wealthy associates. Many were connected through business and social links to Carnegie Steel.

Development included lowering the dam to make its top wide enough to hold a road for a carriageway and putting a fish screen in the spillway. Workers lowered the dam, which had been 72 feet (22 m) high, by 3 feet (0.91 m). These alterations are thought to have increased the vulnerability of the dam. Moreover, a system of relief pipes and valves, a feature of the original dam which had previously been sold off for scrap, was not replaced. The club had no way of lowering the water level in the lake in case of an emergency.

The Pittsburgh speculators built cottages and a clubhouse to create the South Fork Fishing and Hunting Club, an exclusive and private mountain retreat. Membership grew to include more than fifty wealthy steel, coal, and railroad industrialists.

Lake Conemaugh at the club's site was 450 feet (140 m) in elevation above Johnstown. The lake was about 2 miles (3.2 km) long, about 1 mile (1.6 km) wide, and 60 feet (18 m) deep near the dam. The dam was 69 feet (21 m) high and 931 feet (284 m) long.
