Water Level Predictions from the NOAA

The City of Columbus Junction and local businessmen held a meeting this morning at 8:15 to discuss potential flooding. Estimates from the NOAA still have the river cresting at approximately 27 feet, which would put the river below the level of the road and Columbus Junction Levees. Those predictions do not take into account any future increases in flow rate from the Coralville Reservoir. Increases in the flow rate from the Coralville Dam will increase throughout this week and into next. It becomes a question then of how much the reservoir’s opening will affect water levels, and also whether any potential rain moving through the area could change water levels.

Pre-emptive measures have already been taken, in case the river does reach worse case scenario. Cole Construction and Jay Kemp of Kemp & Sons  have placed dirt on top of the levee, effectively raising the height of the levee 3-5 feet. Large (3 feet by 3 feet by 3 feet) sand bags are also in place, in case Highway 92 would need to be blocked off. The city is erring on the side of caution, but does not recommend evacuations at this time. If you have any questions regarding the flood or safety, feel free to call the City at (319)728-7971. Meetings are also being held twice a day, at 8:15 AM and 1:30 at City Hall to discuss preparations. Anyone is welcome to come.

Also, an important reminder: Do NOT drive through running water or an inch or more of standing water on roads. It is dangerous, and should be avoided at all costs.
