Winnings at Baton Rouge’s three riverboat casinos plunged in November, dropping 10.1 percent from what they brought in during November 2013.

The riverboats brought in $21.7 million in November, compared with almost $24.2 million in November 2013, according to figures released Thursday by State Police. This breaks a four-month streak of the Baton Rouge market recording a gain in winnings over the year before.

L’Auberge, the newest casino in the market, had the biggest drop in revenue, falling from $13.4 million in November 2013 to $11.7 million, a 12.6 percent drop. The riverboat still brought in more than the combined revenue generated by the Belle of Baton Rouge and Hollywood Casino.

The Belle, the oldest casino in the market, fared the best in November when compared with the year before. The downtown casino brought in nearly $4.8 million in November, down 3.4 percent from the $4.9 million it generated in 2013.

Hollywood Casino, the other downtown property, had a 9.9 percent drop in winnings. The casino generated $5.2 million in November, compared with almost $5.8 million in the year before.

Statewide, the 14 riverboats, four racetrack slot casinos and Harrah’s land-based casino brought in nearly $195.1 million in November, 5.5 percent worse than the $206.5 million the gambling halls won the year before.

Winnings in the New Orleans casino market dropped by 7.3 percent in November when compared with the year before. The three riverboats, Harrah’s land-based casino and slots at the Fair Grounds brought in $51.4 million. That compares with the nearly $55.5 million in winnings during November 2013.

The lone bright spot was Treasure Chest, which brought in $7.9 million in November, a 4 percent gain over the year before. Harrah’s, which accounts for the biggest share of the local casino market, was the biggest loser. The land-based casino brought in $26.8 million in November, down 13.6 percent from the year earlier.

Lake Charles was the only casino market in the state to post a gain in November, with winnings at the two riverboats and Delta Downs slots going up by 3 percent from $56.9 million to $58.6 million.

The city should post a similarly strong performance in December because the Golden Nugget riverboat casino opened for business last week.

Shreveport-Bossier City was down 10 percent, with the six riverboat casinos and the slots at the Harrah’s racetrack bringing in $56.3 million.

The Opelousas market, represented by the slots at Evangeline Downs, was down by 4.5 percent to $7.1 million.
