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.

Separated from the rest of the Iowa Great Lakes, Big Spirit has a lot to offer. Big Spirit is actually located in Iowa and in Minnesota. This quiet setting offers a number of different lake views as well as access to fantastic fishing. While your are there, stop at the Spirit Lake Fish Hatchery. Every year they use gillnetting to catch and release walleye, muskie and pike using each fish to help breed a new batch of fish for the year. Often times the DNR catches very large fish and put them on display in one of their many fish tanks. The DNR professionals harvest fish eggs and release them after they hatch. Stop by and see the in the Spring, you will not be disappointed.
