Citing damages of $605,000 so far, the Codington County Commission approved a disaster declaration because of flood damage to roads, bridges and other infrastructure in the county.
The declaration is the first step in getting federal money to help pay for repairs.
The county's emergency management director, Jim Sutton, said damage reports are still pending from some towns and townships. The highway superintendent said damage is more than $227,000 just to gravel roads.
It's the second straight year for a disaster declaration in Codington County.
