(Lawrenceburg, Ind.) - New revenue numbers are in for Indiana’s casinos, perhaps showing the effects of new casinos opening in Ohio.

In July, southeast Indiana’s three riverboats – Hollywood Casino in Lawrenceburg, Belterra Casino Resort & Spa in Switzerland County, and Rising Star Casino in Rising Sun combined for $53,966,596 in revenue. The number is a nearly $8 million, or 12.9 percent, decrease from July of 2011.

Since last year, two casinos have opened in Ohio. The Hollywood Casino Columbus, Ohio will open in the early fourth quarter of 2012, followed by a fourth casino in nearby Cincinnati scheduled to welcome the public to its gaming tables in 2013. As a possible side-effect, July attendance at the three area riverboats totaled 547,002, a decline of 13 percent from the same month a year ago.

Each of the casinos experienced similar downfalls in their numbers. Hollywood Casino took in $33.3 million in revenue, a 13.4 percent drop, while the number of visitors at the casino dove 17.8 percent to 284,385 in July.

Belterra Casino revenues were off about 15 percent to $12.6 million. Attendance weakened by 5.5 percent to 150,209.

Rising Star Casino in Rising Sun saw revenues fall 6.5 percent to $7.9 million. The riverboat took a 10.3 percent hit in attendance to 112,398.

Statewide, numbers at Indiana’s 13 casinos did not see as large an impact from Ohio in July. Revenues fell 8.8 percent to 225,302,814. There were 2.22 million visitors, down 3.9 percent.
