MADISON, Wis. (AP) — Flood damage to public roads, bridges, dams and other structures in southern Wisconsin this month is estimated at more than $15 million.

The Wisconsin State Journal reports that the state Emergency Operations Center said Tuesday that Gov. Scott Walker has declared 20 counties to be in a state of emergency.

The damage to public infrastructure was worst in Racine County, with almost $4 million in damage, while Lafayette County reported about $3.5 million in damage.

Meanwhile, Iowa Gov. Kim Reynolds has issued a disaster proclamation for four counties in northern and eastern Iowa ravaged by severe weather, heavy rains and flash flooding.

The governor's office said Tuesday that the proclamation covers Chickasaw, Dubuque, Floyd and Kossuth counties affected by weather Friday and Saturday.
