It was a historic year for Lake of the Ozarks when it comes to lake levels and flow. Two flooding events, one in July, the other in December, pushed the lake to levels not seen in decades. The difference between the lowest level of the year and the highest was over 10ft!
Even from just the thumbnail image below, we can see the standout times when levels and flow were at their extremes.
