A small rise in Mississippi River levels has prompted the U.S. Army Corps of Engineers New Orleans District to start levee inspections, according to a news release Thursday.

The corps started patrolling levees along the east bank of the river from Baton Rouge south and on the west bank from Donaldsonville to Venice. Inspections will be done twice a week until the river level drops below 11 feet at the river gauge in New Orleans.

The National Weather Service’s Lower Mississippi River Forecast Center long-term forecast shows river levels in New Orleans getting to a height of 12.9 feet on Feb. 15 before starting to fall below 11 feet on Feb. 20.

In Baton Rouge, the river stage on Thursday was 30.6 feet with a forecasted rise to 31.3 feet on Feb. 15 before river levels start to fall again.

Until river levels fall below 11 feet in New Orleans, certain work around the levees is prohibited, such as transport of heavy loads over the levees, disturbance of grass cover or subsurface work within 1,500 feet of the levee.
