The National Weather Service has raised the crest of the Mississippi at Vicksburg by foot, from 51 feet to 52 feet.

The river is supposed to reach 52 feet — nine feet above the 43-foot flood stage — Jan. 16. Warren County Emergency Management Director John Elfer said a telephone conference with the National Weather Service and other local officials about the flood is set for 2 p.m. today.

“We are expecting a significant flood event,” Elfer said.

The 52-foot crest is five feet below the record 57.1-foot crest set in the 2011 spring Mississippi River flood. The record level was nine-tenths above the level set in the 1927 flood.

At 51 feet, Elfer said, water will be over Mississippi 465, the main road to Eagle Lake, forcing residents there to use the back levee road to get to Vicksburg and other areas. The levee on which the road runs, however, is being elevated and the road is closed in spots between Eagle Lake and Chotard Resort.

He said the high water should not make U.S. 61 north and south impassible, “but there will be flooding on the west side of the highway. Areas like LeTourneau will be under water.”

Closer to the city, high water will affect the Chickasaw community and areas in the Kings community and Ford Subdivision. At 52 feet, Elford said, the Kings community and Ford Subdivision in the northern part of the city off North Washington Street, will be under water, and at 41.5 feet water will begin to flood Chickasaw.

“It looks like it will be a long January,” Elfer said.

Other local areas impacted include:

• At 36.5 feet water begins to affect the Long Lake Community, and the low road to Kings Island becomes impassable.

• At 38.8 feet, the Vicksburg floodwall Gate at Crawford Street is closed.

• At 39.5 feet, Long Lake Road to Eagle Lake Road becomes impassable about 1 mile north of the Long Lake Community.

• At 40.5 feet, Shady Lane Drive becomes impassable, and Long Lake Road becomes impassable just north of Cypress Drive.
