Referred to locally as the lake turning over the thermocline is a feature of lakes with deep water. The water on the top of the lake changes temperature much more variably during the year. On West Lake, it can reach as much as 75 degrees in July while the water below, greater than 35 or 40 feet deep is relatively stable around 45 degrees. In the fall and early winter, the top strata of the lake will cool to below 45 degrees, and then because it becomes denser, it will "sink" below the lower strata, thus, displacing it and making the lake "turn-over". In the deepest part of West Lake (near the 136ft mark), no light is availble, and hence little life is known whether fish or plant. Typically questions are raised as to why the surface water gets dirty for a short period of time in the fall, this this is the standard answer.

Bringing back the old Okoboji general store from 1884, the Okoboji Store has made a huge name for itself since it opened in 2015. The Okoboji Store is nearly always busy, thanks to their amazing food and drinks. They serve breakfast, lunch, and dinner, during the summer and fall. The restaurant also hosts some of the areas best live musicians, which is always a great time. But, the best part of the Okoboji Store is of course, the view of the lake. Its beautiful location is sure to keep anyone coming back for more.
