TWIN FALLS, Idaho - A slow-moving weather system in south-central Idaho that the National Weather Service is calling a 100-year storm dumped nearly 3 inches of rain on Twin Falls and caused widespread flooding.
Twin Falls City Manager Travis Rothweiler tells The Times-News that the city's drainage system on Wednesday became overwhelmed, causing flooded streets, homes and businesses.
Rothweiler says sewage backed up into seven homes in the city, and that state and federal agencies have been notified.
He says the city's drinking water that comes from far underground remains safe.
Lithia Chrysler Jeep Dodge General Manager James Kieffer says floodwater damaged 50 vehicles.
Mudslides occurred in the Snake River Canyon and Rock Creek Canyon, taking out part of Rock Creek Park.
Officials haven't supplied damage estimates for the city.
