A GRADUAL INCREASE IN FLOW EXPECTED FROM THE MORGANZA SPILLWAY
OVER THE NEXT FEW DAYS...

A RECORD BREAKING FLOOD WAVE CONTINUES TO TRAVEL SOUTH ALONG THE
MISSISSIPPI RIVER...WITH SIGNIFICANT IMPACTS EXPECTED ALONG THE
ATCHAFALAYA RIVER. THE LATEST RIVER FORECASTS FROM THE LOWER
MISSISSIPPI RIVER FORECAST CENTER ACCOUNT FOR A FULL OPENING OF
THE BONNET CARRE SPILLWAY LOCATED IN ST. CHARLES PARISH...WHICH
OCCURRED ON MONDAY MAY 9.

IN ADDITION...THE MORGANZA SPILLWAY IN POINTE COUPEE PARISH HAS
BEEN PARTIALLY OPENED TO REDUCE THE LEVEL OF FLOODING ON THE
MISSISSIPPI RIVER. OFFICIALS WILL GRADUALLY INCREASE THE NUMBER
OF BAYS OPEN ON THE SPILLWAY OVER THE NEXT SEVERAL DAYS. THE
OFFICIAL FORECASTS FOR THE ATCHAFALAYA BASIN NOW REFLECT THE
PROJECTED OPENING OF MORGANZA AT 20 PERCENT CAPACITY.
HOWEVER...IF THE OPENING OF MORE GATES IS REQUIRED...FORECASTS
CRESTS WILL BE ADJUSTED ACCORDINGLY.

THE FOLLOWING TABLE LISTS THE OFFICIAL FORECAST FOR THE
ATCHAFALAYA RIVER. DUE TO SOME ADJUSTMENTS IN THE STREAMFLOWS ON
THE RED RIVER...THE FORECAST CRESTS FOR UPPER PORTIONS OF THE
ATCHAFALAYA RIVER (ABOVE BUTTE LA ROSE) HAVE BEEN LOWERED
SLIGHTLY.

IT SHOULD BE NOTED THAT WHILE THE OFFICIAL FLOOD STAGES ARE
LISTED BELOW...MOST POPULATION CENTERS ARE PROTECTED BY FLOOD
CONTROL LEVEES TO MUCH HIGHER LEVELS.

IN ADDITION IT SHOULD ALSO BE NOTED THAT SOME LOCATIONS MAY
EXPERIENCE FLOODING BEFORE FLOOD STAGE IS REACHED. IF YOU ARE A
PROPERTY OWNER ON THE UNPROTECTED SIDE OF THE LEVEE...PLEASE LOOK
AT THE FORECAST AND DETERMINE IF YOUR PROPERTY IS AT RISK OF
FLOODING.
