Shamokin Dam, Pennsylvania

The Adam T. Bower Memorial Dam (formerly known as the Sunbury Fabridam) is the world's longest inflatable dam. The dam is located just below the confluence of the Western and Main Branches of the Susquehanna River, in Upper Augusta Township, between the town of Shamokin Dam and the city of Sunbury, Pennsylvania. The dam is 2,100 feet (640 m) long. When it is raised in the summer time, it creates the 3,000 acre (12 km²) Lake Augusta, which is used for recreation. The dam and lake are part of Shikellamy State Park. In 2001, the dam was renamed for Adam T. Bower, Chief Clerk of the Pennsylvania House of Representatives from 1967–68 and Director of Services during the Pennsylvania Constitutional Convention of 1967-68, by Act 2001-5 of the Pennsylvania General Assembly.There are plans underway to add a fish ladder to the dam. The fish ladder is primarily to allow the American shad to access the upper part of the Susquehanna. For the 2007 season the dam was slated to be deflated slowly over the period from August 20 through August 23. This earlier than usual lowering of the dam was to facilitate the replacement and repair of at least 3 of the synthetic bags which comprise the dam.

Shamokin Creek (also known as Great Shamokin Creek or Middle Branch Shamokin Creek) is a tributary of the Susquehanna River in Northumberland County, Pennsylvania, in the United States. It is approximately 32.4 miles (52.1 km) long and flows through Mount Carmel, Mount Carmel Township, Coal Township, Shamokin, Ralpho Township, Shamokin Township, Snydertown, Upper Augusta Township, and Sunbury. The watershed of the creek has an area of 137 square miles (350 km2). It experiences significant impacts by abandoned mine drainage and many abandoned mine drainage discharges are in its watershed. Various other impairments also affect parts of the creek's watershed. Shamokin Creek is in the Appalachian Mountains section of the Ridge and Valley physiographic province. Rock formations consisting of sandstone, shale, and anthracite deposits occur in the watershed. The main land uses in the watershed of Shamokin Creek are forested land and agricultural land, with barren land and urban land making up only a few percent of the watershed. However, in the upper 54 square miles (140 km2), forested land and mine spoils dominate, urban land is less prevalent, and agricultural land is virtually nonexistent. Coal mining was being done in the watershed of Shamokin Creek by the early 1800s. In the early 1900s, coal mining, foundries, iron works, nail production, agriculture, silk mills, and woolen mills were the main industries in the watershed. In the 1990s and 2000s, many grants for restoring the creek have been received by various organizations. The main stem of Shamokin Creek is designated as a Warmwater Fishery and a Migratory Fishery. The creek is devoid of fish life in its upper reaches, but several fish species have been observed further downstream. The upper reaches of the creek also lack macroinvertebrate life. The lower 21.6 miles (34.8 km) of the creek are navigable by canoe for part of the year. Pennsylvania State Game Lands Number 165 is also partially in the watershed.
