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.

Having lived in Okoboji all my life, there are a wealth of memories of Arnolds Park. I, like many of the locals, miss the nostalgia of the old Roof Garden, the fun house, the water slide and much, much more. With time comes change, and the amusement park continues to reinvent itself. Currently with over 20 rides to choose from, the family is sure to have a good time. The main attraction, The Legend Roller Coaster, is the 7th oldest coaster in the United States and apparently the 13th oldest in the world. Reaching speeds of up to 50 mph, the roller coaster has undergone substantial renovations in the last year. In front of the amusement park on West Lake is the Queen II excursion boat, and Pirate Jacks Bar. The sunsets here are unparalleled. If you have a chance to visit, make sure to check out the tipsy house, the three sons, and all of the shops. Just to the east is the green space, which provides great entertainment and in 2013 OAR came to play, which is a pretty big name for Okoboji.
