operation was getting results approaching pumping out of Orleans, East Orleans and St. Bernard parishes. In the 17th Street Bridge area, watermarks on homes showed evidence of at least a six-foot drop in water levels. In Plaquemines Parish, five of ten permanent pumps are pushing over 4,100 cubic feet per second (116 m³/s). 27 of 104 permanent pumps and 43 temporary pumps were running, pushing more than 13,000 cubic feet per second (368 m³/s) out of the metropolitan New Orleans area. Corps crews in Saint Bernard Parish cut the roadway at Highway 48 to allow drainage to Pump Station 8. At Pump Stations 1, 4, 6 and 7, the Corps installed booms or floating oil barriers to protect facilities from oil hazards. The Corps continued to monitor the area. Crews also installed a temporary roof at Pump Station 7, enabling the station crew to begin necessary maintenance. The unwatering mission in St. Bernard Parish was expected to be completed within the next week. In East Orleans, four more portable pumps were to be added in support of Pump Station 15 to increase the overall capacity to 1,100 cubic feet per second (31 m³/s). For the first time, the Jahncke Pump Station ran at its full capacity of 1,200 cubic feet per second (34 m³/s). Citrus Pump Station and St. Charles Pump Station each were running at half capacity because the Citrus Pump Station has to pull power from a generator at one of the other two stations. Total possible capacity for these two stations is 1,750 cubic feet per second (50 m³/s). The Corps cleared the rock dike at Lake Shore Drive, removing sheet pile, and raising wire sheet to allow Pump Station 3 to continue pumping at a high rate. Corps personnel were monitoring both breach sites at London Avenue Canal around the clock. Corps contractors were expected to complete the road to the second London Avenue breach the following day. Halfway done By September 15, 2005, the inundation of the city had been reduced from 80% to 40%, although flooded areas were not expected to be habitable for a long while. In Orleans Parish, most of the Ninth Ward of New Orleans and the southern part of Orleans Parish were dry enough for normal recovery operations to begin. Water remained in the northern part of the parish and would be pumped out using Pump Stations 12 and 4,
