The Atlas of Oregon Lakes is a resource for the public, resource management agencies, and scientists to enhance management and enjoyment of our lakes. The online atlas is an updated version of the popular Atlas of Oregon Lakes published in 1985.

The online atlas highlights lake and reservoir water data stored within the Pacific Northwest Water Quality Data Exchange (PNWWQX). The PNWWQX collaborates between a variety of information management projects to facilitate the aggregation of and access to a comprehensive source of data related to water quality in the Pacific Northwest. The PNWWQX was initiated by funds allocated from the EPA Exchange Network Grant program.

The online Atlas of Oregon Lakes was developed by Portland State University's Center for Lakes and Reservoirs, Center for Spatial Analysis and Research, Nohad A. Toulan School of Urban Studies and Planning, and Academic and Research Computing. Funding was provided through an EPA Exchange Network Grant administered by Oregon DEQ and through contributions from Portland State University.
