What the National Weather Service wrote

The Rock River at Newville rose to Moderate flood stage. Flood waters surrounded some homes near East Mallwood Drive and were into yards and roads across eastern Newville. Floodwaters affected a riverside restaurant and its parking lot on the south side of the river.

The wider storm

There was extensive river flooding along the Wisconsin River, Fox River, and Rock River in southern Wisconsin in April. The river levels were above normal after 5 inches of rain fell over the 5 days, and then another episode of heavy rain of 3 to 5 inches occurred on April 17th. In addition, vegetation was still fairly dormant so the grass was not able to soak up much of the rainfall.

Began near Charlie Bluff (42.8100, -88.9800).
