TMDL Projects for Low Dissolved Oxygen

Current TMDL projects for water bodies where conditions are not optimal for fish and other aquatic life due to low concentrations of dissolved oxygen.

Oxygen gas, which dissolves in water, is essential for the survival of aquatic life. While the amount of dissolved oxygen in water fluctuates naturally, various human activities can cause unusually or chronically low dissolved oxygen levels, which may harm fish and other aquatic organisms.
