In the Water Temperature graph, one can see the disturbance at the various temperature depths, which normally are fairly straight lines over time in season. This disturbance is due to a combination of water at various depths mixing and water flowing to and from the several basins within the lake.
Graph 2 shows the maximum and mean wind speeds during the storm. Notice the maximum of only 36 mph, but a near zero as the eye of the storm passed.
The Graph 3 indicates an impressive wind change, again as the storm passed.
The PDF above indicates water temperature and dissolved oxygen changes near the surface changes.
