Ontario Stream Assessment Protocol (OSAP)

The Ontario Stream Assessment Protocol (OSAP) is a provincially recognized protocol that contains standardized sets of methods that allows both professionals and volunteers alike to identify sites, evaluate benthic macroinvertebrates, fish communities, physical habitat and water temperature in wadeable streams.

The OSAP methodology allows for data to be standardized and ensures that the methods of collection are repeatable and comparable from stream to stream across the province. The advantage of this data is that it has been designed to be shared and can be used for multiple purposes and is stored in a common database that has multiple users.
