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.

Miller's Bay, on the west side of West Lake is a popular spot for boaters in the summer to just go chill out, throw an anchor, and relax. On the weekends, this bay is filled with boats tied up to each other offering families the opportunity to have the kids swim, or you might find a bunch of party animals chugging beers and enjoying the summer sun. Either way, everyone is having a great time, and so if you are out and about, just know that Millers Bay is where boaters go in the summer to be where the party is at.
