In this engaging program, the complexity of the Ontario Stream Assessment Protocol is summarized to highlight those measurements that are most integral to the efficient management of a watershed by conservation authorities. Students spend the morning at our ponds in order to collect benthic macroinvertebrates and appreciate what their relative populations can reveal about the health of their aquatic habitat. In the afternoon, students travel to our headwater stream for an introduction to abiotic stream measurements and the use of rating curves for flood forecasting. Students demonstrate their learning by completing a gallery walk of stations along the stream in the Ganaraska Forest.
