IRCA: IWW Lock Status Update ICE Conditions.pptx


Please see below and attached for ILWW ice conditions and ice coupling requirements at Peoria and LaGrange Locks (when LaGrange begins locking).  Ice couplings are recommended for Dresden Island, Marseilles, and Starved Rock Locks, but not required at this time.


I will forward any updates as I receive them.

Here is the inaugural slide for ice season 2022!  Hopefully it’s a short one.  Ice has formed in the lakes above at and above Peoria and creating an ice coupling requirement at Peoria Lock.  LaGrange is expected to raise their dam in the next couple of days and with the forecasted overnight lows and the dam slowing the river down ice conditions will develop rapidly and an ice coupling requirement will be in effect.


If you have any questions, feel free to reach out to me at any time.
