Visitors to Lake Garrison may notice the rich, amber-brown color of the water and wonder whether it is safe for swimming. This distinctive hue, often described as “Cedar Water,” is completely natural and perfectly safe. While it may appear unusual to those accustomed to clear, blue lakes, there is no need for concern. This coloration is a hallmark of the lake’s unique ecosystem and does not indicate pollution or unsafe conditions.

The color of Lake Garrison’s water comes primarily from tannins, which are naturally occurring compounds released from surrounding vegetation such as cedar trees, oak leaves, and other plant matter. When leaves and plant material decompose, tannins are released into the water, giving it a tea-like appearance. This is the same phenomenon observed in many rivers, ponds, and lakes in forested areas across the United States. Tannins are harmless to humans and animals and do not affect water quality in any way that would make swimming unsafe.

It is important to note that the presence of tannins actually contributes to a healthy aquatic ecosystem. Tannins help maintain the natural acidity of the water, which supports a diverse range of aquatic plants and wildlife. Fish, amphibians, and other wildlife thrive in these conditions, creating a balanced and vibrant ecosystem. Swimmers can enjoy Lake Garrison with full confidence that the water is clean and safe, despite its unusual color.

Lake Garrison undergoes weekly water quality monitoring to ensure that it meets safety standards for recreational use. Testing for bacteria and other indicators confirms that the lake is safe for swimming, boating, and other recreational activities. No studies have linked the tea-colored water to any health risks. On the contrary, the lake’s water quality consistently meets or exceeds the standards set by state and local health authorities.

While the color may seem unusual, visitors can take comfort in knowing that Cedar Water is not dirty; it is a natural feature of the lake. Swimmers are encouraged to appreciate the lake’s unique character and enjoy the numerous benefits it offers.

For families and individuals seeking a refreshing and safe outdoor experience, Lake Garrison provides an exceptional opportunity to connect with nature in a pristine setting.
