The Unique Geology of Torch Lake Michigan
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?
Unique Limestone Geological Formation
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.
Regular Monitoring By The Department Of Natural Resources
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.
Algae Blooms and Runoff Connection
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.
Strict Regulations
Because Torch Lake is such an asset to the Michigan lakes community, strict regulations surrounding the lake have been put in place. Motorized vessels are not allowed on the lake, and all boats must have drains plu-plugged to avoid unhealthy runoff from entering the lake. All boats are also required to have their hulls inspected prior to entering the lake and they must be free of visible plant material as this could introduce dangerous invasive species into the lake.
Legacy of Conservation
The Michigan Department of Natural Resources works closely with the Torch Lake Protection Association, an organization dedicated to preserving the lake’s excellent water quality. Efforts undertaken by the Association and the Michigan Department of Natural Resources include reducing invasive species, addressing the phosphorus and sediment run-off issue, and ongoing water testing and monitoring. Furthermore, the Lake is patrolled by Department of Natural Resources officers to ensure regulations and conservation efforts are upheld.
Other Environmentally Conscious Practices For Torch Lake
Other practices putting into place in order to protect Torch Lake include prohibiting the disposal of soaps, detergents and other cleaning products directly into the lake. To avoid such run-off, residential homeowners are encouraged to use biodegradable products that help to keep the lake clarity at its best. Additionally, Lakefront residents have been encouraged to take part in research projects, such as riparian buffer zone establishments, in order to promote natural shoreline protection. This help to keep the shoreline clear of debris and prevent trees from becoming overgrown and contributing to turbidity.
The Local Torch Lake Economy
Torch Lake is not only beneficial to its surrounding environment but also to the local economy. Each summer, thousands flock to the lake to enjoy its beauty and partake in the many activities on offer, such as fishing, boating, swimming, camping and hiking. Tourism provides a valuable income to the region and encourages people to learn more about the Lake and its environmental importance.
The Magnificent Color of Torch Lake
Despite its deep depth, Torch Lake remains crystal clear in part due to its flora and fauna. On most days visitors will enjoy the breathtaking aquamarine color of the Lake which is a result of the refraction of sunlight as it passes through both its surface and the organic particles it contains. The result is a deep, mesmerizing color that captivates tourists each and every time.
The Health of Torch Lake
Residents of the surrounding counties can be grateful for the exceptional health of Torch Lake, which is due to recent conservation efforts that have been set in place to help maintain its clear, debris-free shores and waters. Research projects determined that run-off from fertilizers and other soil erosion sources had began to impair the Lake’s clarity and threatened its pristine beauty. As such, local authorities have worked diligently in order to protect and revive Torch Lake, with exceptional results.
The Grand Traverse Bay and Torch Lake Connection
Torch Lake is connected to the Grand Traverse Bay by the Clam River and is an important body of water that feeds the extensive Great Lakes system. This connection helps to increase the amount of fresh water entering the Bay, which in turn helps to maintain sensible water levels and clarity. By limiting river inflow and outlet flow, Torch Lake helps to keep the bay relatively consistent in terms of temperature and clarity.
Conclusion
Torch Lake Michigan is a magnificent lake situated in Michigan’s Antrim, Kalkaska and Grand Traverse counties. Its incredible clarity and health is largely due to the distinctive geologic formation of the Traverse Limestone located beneath its waters, as well as the numerous local conservation efforts aiming to preserve its beauty. The remarkable aquamarine coloration of the Lake is a sight to behold and its connection to the Grand Traverse Bay helps to keep the characteristically clear waters of central Michigan free of debris.
