Dissolved Oxygen (mg/L)

Dissolved oxygen is consumed in the water by respiration and decompostion. It is replenished mainly by the atmosphere and also by photosynthesis. Also, water temperature is a key factor in the regulation of water's oxygen levels. Warm water contains a less oxygen concentration than cold water. If concentrations get too high, though, the dissolved oxygen can become toxic.
