Talk about it

OSHKOSH - Folks on Lake Winnebago near Oshkosh could see some rare flooding – but it’s expected to be minor. And forecasters say it will only affect low-lying areas consisting mostly of boat-docks and back yards.

The National Weather Service said the lake’s flood stage at Oshkosh is three-and-a-half feet, and it was at that level at one this morning. A flood advisory is in effect until tomorrow morning on Lake Winnebago at Oshkosh. Also, a flood warning continues on the Fox River near Berlin, where four-inches of rain fell a week ago. The river was a foot-and-a-quarter above its flood stage at four this morning. But again, only minor floods are expected. Forecasters expect the Fox to maintain its current level at least through tomorrow morning.

Some parts of Wisconsin had 10 straight days of rain which ended earlier this week. Dry weather is predicted for a second straight day, with sunny skies statewide and warmer temperatures with highs in the 60’s-and-70’s.

Eighteen communities in east-central Wisconsin have reported sewage overflows or related problems as the result of last week’s heavy rains. In Ripon, officials said over two-million gallons of partially-treated wastewater were spilled into Silver Creek last Thursday. The city told the DNR it was trying to prevent flooding at its sewage treatment plant due to heavy flows. In Denmark, near Green Bay, about 150,000 gallons of partially-treated sewage was pumped into Denmark Creek during three hours of overflows. The community had one-point-eight inches of rain the previous 24 hours. Kewaunee said 150,000 of sewage flowed into the Kewaunee River to prevent basement backups. Berlin reported two sanitary sewer overflows on a day when it recorded over four-inches of rain. Parts of east central Wisconsin had four-and-a-half inches of rain on May third. Fond du Lac said it had one overflow incident three days later, when another big thunderstorm hit.
