One of the main tourist attractions in the southeast is Blue Lake. It is the most distinctive and stunning feature of the area. During the summer, it is noted for its deep blue color. The lake is morphologically and chemically distinct from the other lakes. It is also preserved as the town’s water source, keeping it in almost pristine condition.
Why Can This Lake Change Colors?
The following summarizes the prevailing idea from recent studies regarding the famed color change of the lake, from grey in winter to bright blue in summer.
Late November and early December see a brief period of color shift, which deepens during the summer. Blue Lake’s normally clear water turns a vivid shade of blue in the summer for two reasons.
First, more light reaches the Lake’s surface during the summer since the sun is higher in the sky than in the winter. As a result, more blue light is reflected back from the lake by tiny particles. Pure water tends to scatter light in the blue to the blue-green range, while tiny particles like calcium carbonate crystals and dissolved organic matter (tannins) scatter light in the yellow to the brown range.
Second, as the lake surface warms in the spring, dissolved carbon dioxide is released as a gas into the atmosphere, the pH rises, and the water’s calcite content is oversaturated, causing it to precipitate out. Small calcite crystals grow, and as they sink to the lake’s bottom, they catch organic waste, “cleaning” the water as they go. On the lake’s bottom, a fresh layer of calcite that is 3 mm thick and 1 mm thick of organic material accumulates every year.
It is commonly acknowledged that there is an annual calcium precipitation cycle that contributes to the lake’s clarity in the month of November before it turns blue.
