From the report "No quick fix for New Orleans' breached levees", updated at 11:12 p.m. ET Aug. 30, 2005:
As failing levees allowed the murky waters of Lake Pontchartrain to inundate the streets of New Orleans on Tuesday, one thing was becoming clearer: Staunching the flood tide was not likely to be a quick fix.
Confusion persisted for much of the day over where the levees in the below-sea-level city had been breached and how badly. But as evening fell, the most serious problem continued to be "a large section of the vital 17th Street Canal levee, where it connects to the brand new 'hurricane proof' Old Hammond Highway bridge," according to the Web site of the New Orleans Times-Picayune. Smaller breaches were reported elsewhere.
That also has a good aerial shot of the 17th Street bridge.
According to this:
But by Tuesday [Aug. 30], conditions began to deteriorate when the water began to steadily rise. Water lapped at the edge of the city's historic French Quarter after failed pumps and levees sent water from nearby Lake Pontchartrain coursing through the streets.
"It's a very slow rise, and it will remain so until we plug that breach. I think we can get it stabilized in a few hours," Terry Ebbert, New Orleans' homeland security chief told The Associated Press.
Despite that date on that page, that same quote appears in "Katrina devastation called 'overwhelming'" from 02:33 PM PDT on Tuesday, August 30, 2005.
Now, take a look at Josh's timeline here, which, as you can imagine, has a left-wing bias.
