High BOD is generally an indication of the level of material in a water that can be broken down by micoorganisms, usually caused by pollution. The term "high" BOD is relative and can vary based on the type of water body you are examining.

From wikipedia

BOD - biochemical (biological) oxygen demand is a test used to measure the concentration of biodegradable organic matter present in a sample of water. It can be used to infer the general quality of the water and its degree of pollution by biodegradable organic matter. It is used in water quality management and assessment, Ecology and environmental science. BOD is not an accurate quantitative test and should be considered as providing an indicator of the quality of a water body.
