Okoboji Boat Works is home to "The Fish Shack" and "The Inconvenience Store". Formerly a marina of thriving boat sales since 1890, OBW now offers up many different rentals, a 24 hour gas dock, excursion boats, and more. I remember the days as a child of fishing for crappie and blue gill here and along the docks of Smith's Bay. Though the scenery has changed, the outstanding fishing has not.

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.

The harbor is a man made inlet located on the north end of West Lake. A board walk surrounds the harbor and this is one of the most tranquil parts of the lake. Homeowners in the harbor have a more affordable way to have access to West Lake, and still get to enjoy the clean waters West Lake has to offer. Homes in the Harbor typically range from about $350k to as much as $700k.
