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.

If you haven't been to West O, you need to go. With their state of the art brewery, and access to some of the best water in the world, their beer is nothing short of amazing. Their tasting room has a cool, industrial feel, and perfect for tasting their many types of beers. CocO Stout has been an award winning beer for years, and definitely worth a try! West O has been voted "Best Iowa Beer" by the Des Moines Register readers in 2016.

Trappers Bay is nestled along the north shore of Silver Lake. It is a nice quiet little spot to take the family for a weekend picnic or a day of fishing. Silver Lake is one of the few area lakes that has a walleye season year around. Before the big Walleye opener on the Iowa Great Lakes, you will find Trappers Bay lined with fishing the entire length, trying to land a big walleye. Trappers has many fishing spots to choose from, however, on either side of the bridge usually produces the best fishing. Make sure to get there early, or you will likely not get an ideal spot in the early spring. Try casting a twister tail, ripple shad, or use a floating jig tipped with a minnow or leach. Good Luck!
