CLIVE – Having a world-record Powerball jackpot of nearly $1.6 billion proved to be a financial windfall for the Iowa Lottery.

Iowa’s state-run gambling enterprise posted its best year ever in fiscal 2016, with annual sales hitting a record $366.9 million, which generated a record $88 million in proceeds for the state treasury, according to preliminary figures released Tuesday by lottery officials.

Topping the $300 million sales plateau for the fifth straight year enabled lottery players to reap a record $221.8 million in prizes – including six winning tickets that topped the $1 million mark – and netted Iowa retailers $24.6 million in commissions, which also was a yearly record.

The largest prize claimed by an Iowa Lottery player in FY 16 was $2 million. That winner was Bryon Stewart of Onawa, who claimed his Powerball prize on Jan. 14. Five other tickets that were claimed won prizes of $1 million. One of those winners was Joel Dominguez of Sioux City, who claimed his Powerball prize on Jan. 11.

The Hy-Vee store at 20 Wilson Ave. SW in Cedar Rapids topped all Iowa retail outlets with more than $1.02 million in lottery ticket sales for the 12-month period ending June 30, according to lottery data.
