Caption: The average daily dissolved oxygen (D.O.) of the A Canal in 1992 is displayed above. Note that D.O. levels fluctuate from super-saturated (>12 mg/l) in February of 1992 to a low of less than 4 mg/l in late October. High D.O. is generally associated with algae blooms and severe D.O. sags are usually as a result of algae die-offs in Upper Klamath Lake. Since the origin of the A Canal is at the outlet of Upper Klamath lake, the D.O. data may be somewhat representative of the out-flow into Link River. Please note, however, that data probes may catch live or dead algae which may yield skewed results. Click on Info Links for more information on this topic. The data summarized above was collected with a Hydrolab data probe deployed by the staff of the Bureau of Reclamation.
