Water Quality

Why sample water from Lakes?

This question could be best answered in part by another question: why have a medical examination if one is in good health? Sampling of lake water helps to prevent or identify several problems. It also helps direct actions to maintain or improve the health of lakes. How do we know if the layer of cold water at the bottom of the lakes (hypolimnion) is well oxygenated or if there is a lack of oxygen (anoxia)? Does the lake contain a lot of phosphorus and what does that mean? Here is a quick checklist that will allow you to summarize each of the sampling parameters, sampling technique, source and effects on water quality and how to read the results.
