At this time, it is extremely important that residents do not drive on top of dikes within the city.  These dikes are clearly marked with barricades and/or gates indicating that vehicle access is not allowed.  Vehicle traffic has the ability to severely compromise the integrity of the dike which would pose a failure risk.  Anyone found driving around these barricades and/or gates will be charged with Driving Past Barricades; which can result in a court appearance and a fine of up to $600.00.

Sioux City Closes Some Tributary Flood Gates PDF Print E-mail
Wednesday, 08 June 2011 07:08

As the Missouri River level continues to rise, the City’s tributaries are seeing an increasing surface elevation. This elevation can rise to a level where it could back flow into the storm sewer system. While the City does not expect any river water to come out of the inlets or manholes, closing these gates will prevent river water from backing into the system. Both the Big Sioux River and the Floyd River have flood gate structures that can be closed to contain water in their respective channels. Staff has identified gates to be closed on both tributaries and additional gates will be closed as the river rises. The City is evaluating the pumping capacity needs to dewater low lying areas and securing the pumps to perform this task.
