In the Niagara River, the waters of Niagara Falls can sometimes take on a mysteriously mesmerizing green tint, a phenomenon known as "green water." This enchanting color is a result of the water's composition, specifically the presence of dissolved minerals like limestone and calcium carbonate.
These minerals have the remarkable ability to reflect sunlight, casting a greenish glow upon the water's surface. Furthermore, the presence of algae and other aquatic plants can also contribute to the verdant hue. It's worth noting that the water's color can vary, influenced by factors such as weather patterns, the time of year, and the flow of the water itself.
