The WSJ has a roundup of the coverage of the various breaches:
...Yet it wasn't until Tuesday that most people across the country, apparently including Mr. Chertoff, realized that any levees at all had been breached. Did media outlets get it wrong, as Mr. Chertoff claimed? Some did, some didn't.
A look at news reports of the events of Aug. 29 paints a picture of confusion, miscommunication and conflicting information among some government officials and news media. Several major news outlets, including Viacom Inc.'s CBS network and National Public Radio reported the breaking of the Industrial Canal and flooding on Monday, although not all of the reports acknowledged the extent of the devastation. The Wall Street Journal reported the Industrial Canal breach but no others...
Yet some government officials certainly appeared aware of a breach and said so on network television. At 7:33 a.m. on Monday, Aug. 29, Gov. Kathleen B. Blanco said on NBC, "I believe the water has breached the levee system, and is -- is coming in."
In its Aug. 29 online edition, the New Orleans Times-Picayune first reported a breach in the 17th Street Canal levee at 2 p.m., citing City Hall officials. No other major news outlets picked up that report. The newspaper's Web site also reported massive flooding near the Industrial Canal, writing that city officials "fielded at least 100 calls from people in distress in the Lower 9th Ward and eastern New Orleans." At about 2:30, it reported that the Industrial Canal had been breached, citing a National Weather Service report.
But in the hours immediately following the storm, some news organizations seemed to play down the damage in New Orleans. Introducing "World News Tonight" on Aug. 29, anchor Charles Gibson said: "In New Orleans, entire neighborhoods are underwater, but the levees held. The nightmare scenario of an entire city underwater did not happen."
...Officials with the U.S. Army Corp. of Engineers said last week that one canal breach came to the attention of corps personnel early Monday, Aug. 29 and another by midday. But the "fog of war" and "massive logistical problems with communications in the hours after the storm hit" created some confusion, said John Rickey, a spokesman for the corps.
No major newspaper printed a headline that literally said New Orleans "dodged a bullet," as Mr. Chertoff claimed. But some did say the city had escaped a direct hit -- which was true, but misleading -- while others focused on the levees along the Mississippi River. Meanwhile, it was the levees along canals extending south from Lake Pontchartrain that gave way...
