The Online Watershed Library (OWL) a searchable, online database of research articles, stormwater and watershed manuals and plans, assessment tools, regulatory information, and other watershed-related resources. OWL was developed to be a time-saver for watershed and stormwater practitioners as it provides users ready access to a well-organized database of relevant and up-to-date information on watershed and stormwater management.

All Center for Watershed Protection publications are provided free to the public through OWL. To search additional non-Center publications, users must be a current member of CWPA or an OWL subscriber. Due to copyright protection, not all publications included in OWL are available for download and in such circumstances, a link to the publication is provided.
