Notice to Navigators: Illinois River

IRCA: Peoria Lock and Dam Update


The series of ice jams between Peoria and Henry seems to be broken up and flowing now, which will provide the water that Peoria Lock needed to continue safely passing tows over the nav pass.  This is good news for transiting Peoria Lock, but tows and fleets should now be on the lookout for flowing ice and creek debris/drift.  Please see below from Doug Morgan concerning Peoria Lock.

River levels have been slowly on the rise since our meeting yesterday.  We have gained 7 tenths since then and are approaching a half foot over our upper wicket raise point threshold and still climbing.

Unless the river above the lock suddenly experienced a significant ice jam­ that shut most of the water off I can say we are in the clear of passing navigation through the lock chamber.

Thank you to you and the locking committee for your coordination, cooperation and flexibility as we experienced yet another curveball thrown at us by the Illinois Waterway.
