The buildings are largely vacant; however, part of the revamped 14" mill operates in the northern end of the former 13" mill and shear shop. Importantly, the original Southwark steam engine remains in place in the old 36" plate mill, though it has not operated since the 1920s.

  • The 1889 Johnstown, Pennsylvania Flood - a Physics-Based Simulation
    21 The 1889 Johnstown, Pennsylvania Flood - A physics-based Simulation Steven N. Ward Institute of Geophysics and Planetary Physics University of California, Santa Cruz, USA 1. Introduction 1.1 Thumbnail review of the 1889 flood. In 1889 Johnstown Pennsylvania was an industrial workingman’s town, sited on a flat triangle of ground at the confluence of the Little Conemaugh and Stoney Creek Rivers (Figure 1). Johnstown and its neighbors in the valley—Cambria, Woodvale and E. Conemaugh—housed 30,000 residents. Years of industrialization narrowed and channelized the valley’s three rivers to a fraction of their natural widths (Figure 2). As a consequence, nearly every spring Johnstown flooded. Even so, the water was little more than aggravation to town folk who simply relocated carpets and furniture to upper floors to wait out the water’s retreat. On May 30 and 31, 1889 the upper reaches of the Little Conemaugh and Stoney Creek basins experienced the strongest rains in anyone’s memory. The Conemaugh River at Johnstown rose from 1 foot to 23 feet in just over 24 hours. By mid-day on the 31st, water crept over most of the lower town reaching to Central Park. Although everyone agreed that this flood was worse than usual, residents nonchalant about the affair, yet again moved carpets and furniture upstairs. Like floods of the past, the 1889 one would have faded from history if not for South Fork Lake, 24 km up the Little Conemaugh River and 140 meters higher than Johnstown (Figure 1). Also swollen by the strong rains, South Fork Lake rose steadily throughout May 31 and water began running out its spillways at mid-day.

  • Adventures in Flood Control: the Johnstown, Pennsylvania Story
    ADVENTURES IN FLOOD CONTROL: THE JOHNSTOWN, PENNSYLVANIA STORY Joseph P. Kozlovac Urban Areas as Environments April 19, 1995 The city of Johnstown throughout its history has had an unusually high occurrence of flooding. This small Pennsylvania city is located in the south western part of Cambria County which is about 58 miles east of Pittsburgh, the closest neighboring major urban center. The city of Johnstown has an elevation of 1165 feet above mean sea level (as measured in the vicinity known as "The Point".) and is 440 above the city of Pittsburgh. For over a century Johnstowners have been greeted all over the globe in this fashion; "So you are from Johnstown, Pennsylvania! I know that town. That's the place they have the floods."1 Thus Johnstown has been given the notorious name of "The Flood City" by many outsiders. Most of these individuals if questioned about this dubious title invariably bring up the catastrophic flood of 1889 as the origin of this name, however Johnstown's flooding history dates back to at least 1808. One of the factors which contribute to the frequent flooding in Johnstown is its location. The city of Johnstown is situated at the bottom of a relatively narrow, steep-sided valley which to some degree is reminiscent of a funnel. The downtown area lies between Stony Creek and the Little Conemaugh River, which then converge at the point to form the Conemaugh River, one of the Allegheny River's chief tributaries. Stony Creek has several principal tributaries and the Little Conemaugh River has two; The North Branch and the South Fork.

  • Updated 9/2003 Watershed Restoration Action
    Updated 9/2003 Watershed Restoration Action Strategy (WRAS) State Water Plan Subbasin 18E Stonycreek River and Little Conemaugh River Watersheds Somerset and Cambria Counties Introduction Subbasin 18E consists of Stonycreek River and Little Conemaugh River watersheds, part of the Allegheny River basin. The total drainage area is approximately 658 square miles and contains 1049 streams flowing for a total of 1209 stream miles. Stonycreek River is 43.4 miles long and drains 467 square miles or approximately 71% of the subbasin. The average slope is 38 feet per mile. Stonycreek River meets the Little Conemaugh River in the City of Johnstown to form the Conemaugh River, which becomes the Kiskeminetas River in its lower reaches. The Little Conemaugh River is 29.2 miles long and drains 190 square miles or about 29% of the watershed. The average slope is 53 feet per mile. Six watersheds within the subbasin have drainage areas over 30 square miles: South Fork Little Conemaugh River, North Branch Little Conemaugh River, Bens Creek, Shade Creek, Paint Creek, and Quemahoning Creek. The subbasin is part of HUC Area 5010007, Conemaugh River, a Category I, FY99/2000 Priority watershed in the Unified Watershed Assessment. Geology/Topography/Soils: The subbasin is an area of high relief, steep mountains and deep river gorges. The subbasin originates on the Allegheny Front, the western edge of the Appalachian Mountains and the divide between the Susquehanna River and Ohio River basins, at elevations over 2,900 feet. The entire subbasin is within the Central Appalachians Ecoregion. This ecoregion is divided into two parts, the Forested Hills and Mountains (69a) that is restricted to the ridge tops at the eastern and western edges of the basin and the Uplands and Valleys of Mixed Land Use (69b) in the remainder of the subbasin.
