AVOCA ISLAND, La. (AP) — The Louisiana National Guard is building protective barriers around Avoca Island as water levels in the Mississippi River rise.

On Friday, the National Guard said its units had begun transporting 12,550 linear feet of protective levee barriers to Avoca Island, which lies east of Morgan City in St. Mary Parish.

Meanwhile, the National Guard has also been working to erect protective levees in Krotz Springs in St. Landry Parish.

The National Guard says more than 250 of its personnel are involved preparing the state for flooding.

The Army Corps of Engineers is considering to open the Morganza Spillway, which would send swollen Mississippi River water into the Atchafalaya Basin.
