How can temperature affect surface water quality?

Temperature significantly influences both oxygen solubility and metabolic rates in aquatic systems, making it a critical factor in surface water quality. Warmer water holds less dissolved oxygen, which is vital for the survival of aquatic organisms, such as fish and invertebrates. As temperatures rise, metabolic rates of aquatic organisms also typically increase, leading to higher oxygen consumption. This can create an imbalance in the ecosystem, where the organisms require more oxygen than what is available, potentially resulting in hypoxic conditions.

Furthermore, temperature can impact the biological processes associated with nutrient cycling, affecting how nutrients are absorbed and utilized in the aquatic environment. This interplay between temperature, oxygen levels, and metabolic rates illustrates the essential role temperature plays in maintaining healthy surface water quality.
