The Unique Geology of Torch Lake Michigan<\/h2>\n

Torch Lake Michigan is a stunning 18,770 acre lake situated in Antrim, Kalkaska and Grand Traverse counties at the convergence of several other bodies of water. It is the second largest of its kind in Michigan and is well known for its extraordinary clarity and beauty. Tourists flock to the area to enjoy the aquamarine colored lake that takes its name from the shape of its shoreline, resembling an ancient ‘torch’. So why is Torch Lake Michigan so clear and inviting? <\/p>\n

Unique Limestone Geological Formation<\/h2>\n

A massive geological formation known as the Traverse Limestone underlies the waters of Torch Lake. This formation is not only responsible for the lake’s exceptional clarity but also the unique marine life found in its depths. The Traverse Limestone formation is approximately 300 million years old, and this geologic structure helps to keep rivers, streams and lakes clear because the limestone acts like a filter, trapping sediment and other particles before they enter the water. Furthermore, the limestone acts as an effective base for aquatic plants and it is these that give Torch Lake its beautiful emerald green cast and pristine clarity throughout the warmer months.<\/p>\n

Regular Monitoring By The Department Of Natural Resources<\/h2>\n

To ensure the waters of Torch Lake remain healthy, the Michigan Department of Natural Resources monitors them on a regular basis. Their efforts focus on controlling soil erosion from sources such as agricultural fields, gravel roads and residential development, as this erosion can cause turbidity in the water. Most of the Lake is zoned for single family residential use and local ordinances focus on avoiding development that would deteriorate the lake.<\/p>\n

Algae Blooms and Runoff Connection<\/h2>\n

One of the biggest threats to Torch Lake’s clarity is algal blooms, caused when runoff from nearby farms, yards and golf courses introduces phosphorus into the lake. Studies have shown the phosphorus this runoff contains stimulates the growth of certain types of algae, creating huge, unpleasant blooms. Unfortunately, these blooms contribute to the lake’s already poor clarity, reducing light penetration and affecting the lake’s ecosystem.<\/p>\n
