Values in this field were generally obtained from the names in the “An Inventory and Classification of U.S. West Coast Estuaries” (Heady, et. al, 2014), although there are exceptions. Estuaries added to the PMEP estuary list utilized official or commonly used estuary names, the name of the major river or creek connecting with the estuary, or used local landmarks in the absence of another name source.

Note that some values repeat (estuaries were split), some values are NULL (estuaries added to PMEP's list since the report). Values range from 1 (San Juan Islands and Georgia Strait Basin) to 303 (Tijuana River estuary).

This effort developed a comprehensive inventory of U.S. West Coast estuaries by tallying 691 coastal confluences for Washington, Oregon and California. This report also applied the physiographic setting of the Coastal and Marine Ecological Classification Standard (CMECS) to these estuaries. This initial list of estuaries was then reduced to 303 estuaries for the foundational report "Nursery Functions of U.S. West Coast Estuaries: The State of Knowledge for Juveniles of Focal Invertebrate and Fish Species" (Hughes et al 2014), based on a decision tree to limit the estuaries to those that likely support nursery habitat for West Coast marine and anadromous species. From this list of 303 estuaries, PMEP conducted an internal process to refine the list of estuaries. This process included subdividing areas of the Salish Sea (previously grouped into 7 estuary "subbasins") into individual estuaries (n=166), removing certain estuaries (usually based on limited potential to provide current or future fish habitat), subdividing larger estuaries, merging estuaries together, and adding a limited number of estuaries. The area with the most change in this process was the Salish Sea region. PMEP utilized the technical report from the Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) titled "2012-01 Strategies for Nearshore Protection and Restoration in Puget Sound" in an effort to include all "high potential" sites identified in Appendix B of the report in the list of Salish Sea estuaries. Nearly 150 estuaries in the Salish Sea PMEP ecoregion were identified and explicitly included in PMEP's mapping products by cross-referencing the PSNERP technical report's high-potential sites. The current number of PMEP estuaries is 444.
