Current conditions and measurements taken along the Tippecanoe River and Lake Freeman appear to be approaching potential Abnormal River Conditions (ARC).
At this time, lake levels have not been impacted, nor do the current flow rates serve as a predictor that abnormal river conditions will necessarily occur or that lake levels will be impacted.
An ARC event is not triggered until the USGS Buffalo gauge shows a discharge reading of 410 cfs or lower (24-hour average) or Winamac discharges read 300 cfs or less (24-hour average).
Should flows upstream from Lake Freeman continue to decrease, NIPSCO will follow the protocols provided in the Updated Technical Assistance Letter (TAL) issued by US Fish and Wildlife Service (USFWS) on September 7th, 2018, resulting in the following actions:
· NIPSCO will maintain a discharge rate of either: 1.39 times the flow of the previous 24-hour daily average flow measured at the USGS Buffalo gauge or 500 cfs through the Oakdale Dam, whichever is less
· White County EMA alert will be issued to those subscribed for the service
· NIPSCO and White County EMA will issue a joint safety press release
· An update alert will be posted on www.nipscohydro.com
We will continue to keep you posted with any updates.
