Louisiana orders evacuation after Miss. dam threatened

Louisiana officials have ordered evacuation of low-lying areas along the Tangipahoa River because a dam at a state park lake in southwest Mississippi is in danger of failing.

Officials in Tangipahoa Parish, La., fear the water it would pour into the already swollen river would flood low-lying areas downstream from the park.

But Mississippi officials say they don't believe the volume of water in the 700-acre lake at Percy Quin State Park near McComb, Miss., would add enough flow to threaten communities downstream.
