The Fox River near New Munster, WI has crested at a stage of 17.47 feet and is slowly falling.

This water level is over 2’ of the previous flood of record.

The current best estimate forecast shows the following peak river/lake stages sometime in the Sunday to Monday timeframe.

Flooding of this magnitude has not been seen before.

Flood Warning continues for the Fox River at the Algonquin Tail water until further notice.

Flood stage is 9.5 feet, Minor flooding is occurring and Major flooding is forecasted.

The National Weather Service is forecasting up to 1” of rain over the Fox River watershed next 5 days.

The Fox River near New Munster is forecasted to continue to fall, but it will be over one week before it falls below flood stage.

This flow is higher than we have seen on the Chain, so our lake and river stage estimates are interpolated from our known information.

There is some uncertainty because we have no historic record to compare.

The river will continue to rise at the Algonquin Tailwater to near 12.7 feet by Tuesday (July 18th)
morning then begin falling.

The Nippersink Creek near Spring Grove has fallen out of flood stage.
