The I M Canal Aqueduct over Nettle Creek in Morris, Illinois collapsed in 2013. Little has been done to repair the structure since that time. It is estimated that the cost to repair the aqueduct will cost 5 million dollars. In November of 2018, $250,000 was allocated for the clean up.
Because of the issue with the aqueduct, Gebhardt Park has suffered and the canal running through it has become overgrown with weeds.
