Bettendorf's gambling casino posted a slight increase in revenue in fiscal 2016, but the number of gamblers frequenting the Isle of Capri riverboat fell to 823,000, a 16-year low.

The slight uptick in revenues and decline in casino gamblers at the local casino reflected a similar pattern statewide.

Adjusted gross revenues at the state's 19 casinos were up 1.5 percent to $1.437 billion for the fiscal year ended June 30, while admissions fell by .04 percent to 21,538,433 during the 12-month period.
