Dock Street Dam
http://dbpedia.org/resource/Dock_Street_Dam an entity of type: Thing
Der Dock Street Dam ist ein Überfallwehr im Susquehanna River zwischen Harrisburg und im Bundesstaat Pennsylvania der USA. Es befindet sich zwischen der Philadelphia and Reading Railroad Bridge und der John Harris Bridge und staut den Susquehanna vor Harrisburg bei Niedrigwasser um circa 1,2 Meter auf. Bei höheren Wasserpegeln in den Wintermonaten kann die Krone des Wehres unterhalb des Unterwassers liegen, die Staustufe wird somit zu einem Grundwehr und stellt für auftretenden Eisgang kein Hindernis dar.

The Dock Street Dam is a low-head dam that crosses the Susquehanna River between the Shipoke neighborhood of Harrisburg, Pennsylvania, on the east shore and Lemoyne on the west shore. It is constructed of hollow reinforced concrete buttress dam and was built to create recreational depth as a 3-mile lake, provide floor control, prevent mosquitos, and minimize odors. Turbulence downstream of the dam contrasts sharply with the usually placid, lake-like river above the dam. In spite of the dam the Susquehanna is often just a few feet deep at Harrisburg. Proposals have been made to raise the height of the dam in order to enhance the river’s navigability and recreational potential, although the suggestion remains controversial. The present structure has been criticized as creating currents downs

Proposals have been made to raise the height of the dam in order to enhance the river’s navigability and recreational potential, although the suggestion remains controversial. The present structure has been criticized as creating currents downstream that can draw small boats upstream into the dam, an effect that has been cited in at least seventeen drownings. Since 1935, there have been over 30 documented fatalities because of the dam. Solutions have been proposed, including the piling of stone or concrete debris south of the dam to disrupt the current, but have not been implemented. Dock Street, which was between Hanna and Hemlock streets in the Shipoke neighborhood ran east from Front Street to Ninth Street, was eliminated when Interstate 83 and the John Harris Bridge were built.
