Summary
This update is being released due to a possible issue with the readings at the Fox Lake gage. The current
forecast uses the gage reading for Nippersink Lake. This has resulted in an increase to predicted lake
levels. Inflows are still forecasted to peak on Friday at over 6000 cubic feet per second (Figure 1). The
lakes are predicted to crest at approximately 5.94’ (Figure 2); the Lower River is still forecasted to peak
at approximately 5.40’ for the McHenry Tailwater gage (Figure 3), now on Tuesday, April 9th. It is
currently anticipated that all areas of the system will be at or very near Minor Flood Stage.
