“A combination of factors, including a longstanding drought in the area, and the Corps slowing releasing water into the Morganza, to give wildlife a chance to escape, has slowed the water down,” said Scott Lincoln, a hydrologist and forecaster for the National Weather Service.
The flood is now expected to crest at Butte LaRose at the midpoint of the river basin on May 27 at 24.5 feet, and at Morgan City near the Gulf on May 29 at 11 feet. The slower arrival of the flood has given officials and residents more time to prepare.
“We’ve been here for generations, family after family after family, and hurricanes and floods are something you learn to live with,” said Amanda Frederick, who lives in the community of Stephensville, just north of Morgan City in St. Martin Parish.
Sandwiched between two canals, the subdivision where she lives last flooded in 1993. In 2008, Hurricane Gustav tore shingles off her roof, demolished her backyard fence and shed, and broke windows with flying debris.
To prepare for the coming flood, this week Frederick hand-packed 600 nylons bags provided by the parish with sand and has built a three foot-tall mini levee ringing her house.
“We’re expecting about two feet of water in our yards here, so it could be a lot worse, but it’s still a lot of work to keep it out,” she said.
Up the Atchafalaya, residents of Butte LaRose faced a mandatory evacuation order Saturday morning, leaving the hamlet a ghost town. In the nearby town of Henderson, zydeco dance halls that would be packed on normal weekends stand empty.
