Four more river county casinos in Mississippi were expected to re-open on Friday the 27th, bringing to ten the total number re-openings of the 16 river county casinos in Mississippi that were closed due to flooding, according to the Mississippi Gaming Commission.

In Tunica, Bally's, Fitzgerald's and Harrah's also were slated to reopen on Friday, as well as the Rainbow Casino in Vicksburg. The Tunica properties, which began closing on April 28, are the last of the county’s nine to re-open, making the county’s casinos fully open for business in time for the Memorial Day holiday weekend.

The full impact of the closings on the state’s gaming revenue is not yet known. Mississippi’s gaming revenues fell 11 percent to $189.3 million in April, down from $212.1 million in March. The casinos brought in $198.1 million in April 2010. On the Gulf Coast, revenues fell to $87.4 million in April, down from $92.5 million a year earlier. In Tunica, Greenville, Vicksburg and Natchez, revenues dipped to $101.9 million from $105.6 million in 2010.

Larry Gregory, executive director of the Mississippi Gaming Commission, told the Jackson Clarion-Ledger that the decline was mostly due to higher gas prices. "We're a drive-in market on the Coast and also on the river," he said. "People are not coming to the casinos as much when gas was $3 a gallon.”
