The city of Ottawa made the decision yesterday afternoon about 3 to shut the flood gates over the Marais Des Cygnes river in downtown Ottawa. The rains yesterday have swollen the Ol’Mary to near capacity and Ottawa public works director Michael Haeffle says, “Out of concern for public safety it was necessary to close them.” He is concerned with the tremendous pressure the water is putting on the bridge and didn’t want additional pressure from vehicle traffic to add to the stress. The river is forecast to crest at 34.9 feet, but Haeffle believes it could be higher. City policy says, “The gates will be shut when the river reaches 33 feet. Haeffle says, “I didn’t want to wait until last minute. Drivers will need to find an alternative route when using Main Street and Highway 59. There will be signs posted for detours to direct you around the area.” KOFO will keep you informed as to when the gates will be reopened.
