bicarbonate-dominated lake systems

Bicarbonate-dominated lake systems are freshwater bodies where dissolved bicarbonate ions (HCO₃⁻) are the main form of dissolved inorganic carbon. These lakes often occur in areas with high mineral content, such as regions with limestone bedrock, which dissolves and releases bicarbonate into the water. Such lakes typically have alkaline pH levels, promoting specific aquatic life adapted to these conditions. The dominance of bicarbonate influences water chemistry, nutrient availability, and biological processes, often resulting in clear waters with unique ecosystems characteristic of alkaline, carbonate-rich environments.
