Not true. Lake Pontchartrain is not a fresh water lake, it is connected to the Gulf and is probably brackish, there could be sharks there. Even if sharks are not normally in the lake they could have been forced there by the storm surge. A shark was reported swimming down Canal St. but that could have been a rumor or outright lie.

I know I've been 'corrected', Wikipedia states its a 'salt water' lake.

However Wikipedia has been known to slightly wrong on occasion. The USGS only says the water is "brackish", BUT that the lake is polluted as 'heck'.

I'm on a mission to find the salinity content :-)

Also, what about St. Bernard Parish, which is almost entirely under water and which directly faces the Gulf? When we start pumping water out in a steady stream of flow, basically, we are going to have a 1000 square mile chum slick.

it was probably just a lawyer - right now N.O. is the ultimate ambulance chase.
