During most recent winters, there has been a battle between heat and cold, freeze and thaw. One of the features of a Raymore Park winter thaw is the flooding of the wild area across from the parking lot. An increased river flow usually caused by rain, raises river levels and cracks the ice cover. The ice then progressively forms a moving dam and flood which moves gently downstream. In a couple of decades of observing the before and after, I have never seen the process in motion. This January, after the recent thaw, the ice stalled before the river widens above the weir and no doubt will produce some spectacular flooding and subsequent erosion when the next strong rain event occurs.
Considering the cold weather prior to the thaw, the ice is surprisingly thin. The approaching ‘PolarVortex II’ will no doubt consolidate the present ice dam.
