Floodwaters affected yards of homes near Bethesda Park.

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 Waukesha Co Arpt (43.0400, -88.2400).
