Humorously illustrated with wry examples of Gray Larson's humor, this step by step guide to stream monitoring clearly explains how to set up and continue a program to measure polltants in and near a stream which affect its life cycle. Examples of data recording sheets are included, as well as extensive references and explanations of the sources and effects of various water pollutants. The importance of clean water and long range consequences of neglectful management are clarified. Simple enough for the everyday, any- and everyone remotely interested in preserving the environment will want their own copy.
