Cold temps sould lead to fluctuating water levels; unstable ice.
Springfield, IL - The Illinois Dept of Natural Resources is warning of potential weather-related dangers around the Hennepin Canal. The frigid weather is leading to water fluctuations on the canal in the Rock Falls area. This may lead to air pockets under the ice on the Heenepin Canal, creating ice bridges that may break out under pressure. IDNR Conservation Police recommended all visitors stay off the ice until water levels stabilize. Signs posted around the canal state that when snowmobiling is allowed, operating snowmobiles on the canal is "at your own risk." Snowmobiling is only permitted on state property when at least four inches of snow cover is present. Visitors are encouraged to exercise extreme caution and stay off the ice.
