Question: how to calculate percent dissolved oxygen saturation?
Answer: Example: Determine the % saturation of dissolved oxygen in a stream given the following information: Temperature (13 C); DO (7.6 mg/L). Using the monogram above your answer would be about 72 - 75 depending on your line. Another method is to divide 7.6 by 10.6, which is the 100% solubility at 13 C, then multiply by 100.
