摘要：	After an extended dredging season prolonged by extreme low-water conditions in the fall and extending into the winter, dredging crews in the Memphis, Vicksburg and St. Louis engineer districts have wrapped up their work. In the Memphis district, the 36-member crew of the dredge Hurley had a record-breaking 273-day season, moving 14.5 million cubic yards of material between April 26 and January 13, when it returned to its home at the En-sley Engineer Yard in Memphis. A typical season sees the crew working from around May to September, Memphis District Navigation Branch Chief Matt Young said. Instead, the crew got underway in April, performing maintenance dredging where surveys the previous year had indicated some potentially problematic areas. However, starting about September 24, the Hurley started seeing the effects of low water on the Lower Mississippi. "Typically, when we dredge it is to maintain the channel or get ahead of it so there are no closures, but with these conditions we became more reactive, from near the end of September to about mid-January," Young said.
