Northwest Indiana casinos saw a drop in revenue during the month of July.

The region’s three casinos reported total revenues of $69 million for the month, a 4.3% decrease compared to the same time last year.

Hard Rock Northern Indiana, the area’s largest casino, reported a slight dip in earnings, bringing in just over $37 million.

While revenues were down across the board, the casinos remain a key part of the local economy.
