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.

However, with the addition of the YMCA, the racquet club was unsustainable and converted into retail.

The O'Farrell Sister is a historic Okoboji Tradition that one must check out for breakfast and lunch!

'Farrell Sisters History
The O'Farrell Sisters restaurant was born in 1949 at the bridge on Hwy 71, between East and West Lake Okoboji. Edna Mae and Arlene O'Farrell bought the business from Ike Kissinger who was running for Sheriff of Dickinson County.

In the early years the girls were open seven days a week and had a booming business in no time. The fried chicken dinners on Sunday evenings were especially popular. There were times when the line waiting to get in was so long they'd have to lock the door and would often run out of chicken!

In 1959 Arlene married and moved to Tallahassee, Florida with her husband Furman Henderson. Edna Mae and Ferne continued in the restaurant, moving to its present location that same year. This spot had a garden and chicken coup, which was moved to the house across the street.

Ferne died in 1974 and Edna Mae in 1978. Arlene sold the business to nieces Joyce Gapinski, Jo Ann Anderson, Charlotte Sarvie and Cheri Petersen (these are married names). The nieces successfully ran the restaurant from 1979 through 2003. After losing Jo Ann in 1997 and Cheri in 2002, Joyce and Charlotte decided to sell after the 2003 season.
