Water Quality Parameters: Dissolved Oxygen

Dissolved oxygen, often referred to as DO, is simply the amount of oxygen that is dissolved in the water. It is measured in mg/L or ppm and is correlated with the water’s temperature to give a % saturation. When DO levels fall below 8 or 9, most trout and oxygen-sensitive aquatic insect populations like stoneflies […]

The MSP project is funded by an ESEA, Title II Part B Mathematics and Science Partnership Grant through the Montana Office of Public Instruction. MSP was developed by the Clark Fork Watershed Education Program and faculty from Montana Tech of The University of Montana and Montana State University, with support from other Montana University System Faculty.
