Fox River Status Update
July 1, 2014
Inflows to the Chain of Lakes are 1400 cfs based on the stream gages at Fox River near New Munster, Wisconsin and at Nippersink Creek near Spring Grove and are rising. The Chain of Lake stage is 4.7 feet at Fox Lake. Outflows from Stratton Dam are 2280 cfs with a tailwater stage of 3.2 feet. Flows at Algonquin Dam are 2870 cfs with a tailwater stage of 8.5 feet. Last night’s precipitation measured ¾” in Wisconsin, 1” at Stratton Dam, and 2” in Barrington. Therefore, the Fox River is rising more downstream of Stratton Dam then the Chain of Lakes is rising.
The National Weather Service (NWS) is predicting the Fox River near New Munster, WI will rise to a peak flow of 1260 cfs on July 2 and will remain below flood stage. No significant precipitation is forecasted for the next 4 days.
The sluice gates at Stratton Dam are opened and the hinged crest gate at Stratton is partially opened. The hinged crest gate Algonquin Dam is opened 2’ below the spillway crest. The gates will remain at the current settings. The Chain of Lakes and Fox River may rise 1” to 2” by July 3rd but will not reach bank full elevations.
