About Us » Iowa Gaming History

In 1983, Iowa legislators signed the Pari-mutuel Wagering Act into law.

On April 1, 1991, Iowa opened the first riverboat casinos in the country. The three riverboats that premiered that day were the Dubuque Casino Belle; the Diamond Lady in Bettendorf; and The President in Dubuque. They were quickly followed by the launch of the Emerald Lady in Burlington on May 10, 1991.

Since then, successful riverboats and land-based casinos have emerged across the Iowa landscape to bring billions of dollars of economic impact to the state.

Gaming tax revenue generated since 1991.

As a catalyst for economic development casinos have collectively generated more than $6 billion in tax revenue for the state, which has been allocated for many visionary purposes and projects benefiting every citizen. This money funds important programs such as the Environment First Fund, RIIF, Iowa Skilled Workers, Vision Iowa and County Endowment Grants. See how taxes are spent here.
