Fox River Stratton Operations Status Update

 

CURRENT CONDITIONS :  February 8, 2019

 

CURRENT CONDITIONS
 
Most of the Fox River watershed received about 0.1” to ¼” of precipitation as shown on Figure 1. Measured inflows on the Fox River near New Munster, WI are 2480 cfs and appears to be cresting; flows on Nippersink Creek near Spring Grove are 699 cfs and appears to be cresting. The Fox Lake stage is 4.38 ft and the Stratton Dam Tailwater stage is 4.23 ft. The Fox River at the Algonquin Dam Tailwater stage is 8.91 ft. Please note that the freezing air temperatures may affect the river gages.

 

FORECAST
 
The National Weather Service (NWS) is predicting frozen precipitation for the next 5 days in the Fox River watershed. Figure 2 shows that the Fox River watershed may receive ¼” to ½” of precipitation in the next 5 days. The NWS is forecasting the Fox River at Algonquin Tailwater will crest at a stage of 9.2 feet on February 10th with a flow of 3400 cfs.

 

SYSTEM CONDITIONS AND OPERATIONS
 
The sluice gates and the hinged crest gate at Stratton Dam are opened. The hinged crest gate at Algonquin Dam is partially opened. Estimates indicate that the Stratton Dam tailwater may crest at 4.6’ and the Chain of Lakes may crest at 4.7’ on February 11th. Our goal is to continue moving as much flow as possible the next few days without impacting homes.
