Notice to Navigators: Illinois River

IRCA: IWW Lock Status Update ICE Conditions.pptx


Ice couplings are now REQUIRED for Dresden Island, Marseilles, Starved Rock, Peoria, and LaGrange locks.  The extended weather forecast for Peoria indicates that we will endure below-freezing temps until late next week.  Please ask your mariners to pass along any areas of gorging and other concerns so we can keep each other informed of prevailing circumstances.  Please see below and attached for more info.


Be safe,

Here is an updated slide for current ice conditions at our sites.  Ice has formed at all sites with the exception of Brandon Road and floating mooring bits are tied up Marseilles and Starved Rock.
