Due to the imminent failure of the Lake Tangipahoa Dam in Percy Quinn State Park in Mississippi, near the town of McComb, up to 60,000 people downstream in Louisiana need to immediately evacuate, Tangipahoa Parish President Gordon Burgess told local television station WWLTV.
A potential dam break occurred at Percy Quinn Park on the Tangipahoa River, south of McComb, Miss.
[Updated 12:10 p.m. ET] Pike County Civil Defense's latest Facebook update says: "Flood warning for the Tangipahoa River at Osyka. The dam at Lake Tangipahoa, better known as Percy Quin State Park, has been damaged by the torrential rains from Hurricane Isaac, but is intact, and is not leaking. We are monitoring it. All residents below the dam that live along the Tangipahoa River are being notified of the damage."
[Updated 12:07 p.m. ET] As of about 20 minutes ago, a National Guard helicopter was maintaining position over the dam to monitor its integrity, The Times-Picayune reports. As of 11:45 p.m., it was still holding, the New Orleans paper reported.

Interesting. I hope it's more MSM created "panic and doom" and not a real threat. Would suck to have a 6 foot wall of water tearing at you!

Due to the dam failure, water levels on the Tangipahoa River near Kentwood are expected to rise to 17 feet quickly. This is a very similar level to what was experienced in 1990 and 1983. If you were impacted by the floods of 1990 or 1983, leave the area immediately for higher ground.
