As many as 50,000 residents of Louisiana’s Tangipahoa Parish were evacuated today as waters from Isaac, now downgraded to a tropical depression, threatened to breach a dam in Mississippi’s Percy Quinn State Park. Officials began a controlled release of water to keep the dam from failing.
The town of Kentwood was evacuated after a flyover by Louisiana Gov. Bobby Jindal and Tangipahoa Parish President Gordon Burgess. Officials estimated that flood waters could hit homes with 60 to 90 minutes in the event of a dam failure.
