The New Orleans casino market saw its winnings fall by 7.1 percent in January because of a drop in winnings at Harrah’s and the slots at the Fair Grounds.

The market’s gambling establishments brought in nearly $47.8 million during the month, according to figures released by State Police. That compares with $51.4 million during January 2015.

Winnings in every market statewide were down from the previous year, as just a handful of properties brought in more money than they did in January 2015.

Revenue at Harrah’s dropped by 14.1 percent from $26.2 million to $22.5 million.

The casino has blamed its revenue declines on the New Orleans smoking ban, which forces gamblers to leave slot machines and table games for a cigarette.

Winnings at the Fair Grounds dropped by 14.8 percent to $3.5 million from $4 million.

The drops offset gains at the two Jefferson Parish riverboats, which have seen business go up since the New Orleans smoking ban took effect. Treasure Chest saw its winnings go from $8.1 million in January 2015 to nearly $8.5 million, a 4.4 percent gain.

Boomtown New Orleans winnings went up 3.9 percent to almost $9.1 million from $8.7 million.

The Amelia Belle had a 3.9 percent decrease in winning from nearly $4.4 million in January 2015 to nearly $4.2 million.

Statewide, the 15 riverboats, four racetrack slots casinos and Harrah’s New Orleans brought in $207.1 million in January, a 5.8 percent drop from the January 2015 total of $219.9 million.

The biggest percentage decrease in the state happened in Lake Charles, where the winnings at the city’s three riverboats and Delta Downs racetrack were $71.3 million, an 8.9 percent drop from $78.2 million.

Casino winnings at the Baton Rouge riverboats dropped by 1.3 percent in January.
