Dissolved Oxygen

Dissolved oxygen is an essential element for the maintenance of healthy lakes and rivers. Oxygen is both produced and consumed in a river. It is produced or enters a river through diffusion from the surrounding air and as a product of photosynthesis from aquatic plants. Fast-moving water dissolves more oxygen than still water, as the churning motion mixes the air into water. Oxygen is consumed or removed from a river through respiration by aquatic plants and animals and decomposition of organic matter by microorganisms. Dissolved oxygen is lowest in the early morning as the processes that consume oxygen—respiration and decomposition—have continued through the night while photosynthesis has stopped. Dissolved oxygen also is lowest during the summer months since water temperature is higher in the summer and warm water holds less oxygen than cold water.
