CLIVE, Iowa (AP) — Time runs out this week for the winner of a $1 million Powerball prize to claim the money. Iowa Lottery officials say the winning ticket was bought April 11, 2018, at a Casey’s convenience store in the Des Moines suburb of Nevada. The ticket matched the first five numbers but missed the Powerball. The winner has a year to claim the prize. Lottery officials say that means the purchaser will need to get to lottery headquarters in Clive by 4 p.m. Thursday.

Even when Congress authorizes money, the local share of a major flood project is often more than a small town can pay for.
