Iowa gambling revenues for fiscal year 2015 increased slightly thanks to a new casino property in Sioux City, but the decade long decline in admissions and revenues continued at Bettendorf's Isle of Capri riverboat.

Revenues for the fiscal year were down 2.4 percent to $68.5 million, while admissions at the Bettendorf casino dropped more than 8 percent to 848,000 gamblers during the 12-month period.
