Information on Dissolved Oxygen:

Dissolved Oxygen (DO) is the amount of oxygen dissolved in the water. DO is a very important indicator of a water body's ability to support aquatic life. The amount of DO in water depends on several factors, including temperature (the colder the water, the more oxygen can be dissolved); the volume and velocity of water flowing in the water body; and the amount of organisms using oxygen for respiration. The amount of oxygen dissolved in water is expressed as a concentration, in milligrams per liter (mg/l) of water. The optimal DO for adult brown trout is 9-12 mg/l. Human activities that affect DO levels include the removal of riparian vegetation, runoff from roads, and sewage discharge.
