The rescuers could do nothing except to try to determine where the flow might take the boy. Pompa called the village road superintendent, Bob Kesler, to the scene to help map out the sewers.
Pompa and Kesler were standing on top of a manhole cover about 9m away from the ditch when Pompa saw the boy's fingers pop through an opening in the cover.
The boy had found air pocket just beneath the manhole cover and was hanging onto a ladder leading up to the manhole.
The firefighters wrenched the cover open. Pompa and Kesler lifted the boy to safety.
"He was hollering and talking to us and he was able to reach up for us," Pompa said.
The boy was taken to the hospital, and authorities said he was alert and conscious after his ordeal. Pompa said he never got the boy's name.
"I just thank God he was alive and he'd made it that long," Pompa said. "It could have gone a million different ways but this one way it worked out for him."
A string of storms began moving through the region last week, flooding streets and farm fields and cutting power. One man was killed in Madison as he tried to escape from a flooded ditch last week.
State emergency officials said 20 counties have been affected by flooding over the last 10 days. Governor Scott Walker on Wednesday declared a statewide emergency, directing state agencies and the Wisconsin National Guard to assist local authorities as needed. The declaration also is the first formal step toward requesting federal assistance.
Hardest hit has been Wisconsin's southwestern corner. Up to 28cm fell in the region Tuesday to yesterday, forcing evacuations in La Crosse, Vernon and Monroe counties.
