PMEP is a consortium of organizations focused on West Coast fish habitat in the region's estuaries and nearshore marine waters.This point layer represents estuaries present within PMEP's spatial data system. This layer was developed by members of PMEP, based partly on previous estuary inventory efforts as well as the goals of PMEP. Currently, there are 444 estuaries present in this layer, covering the West Coast of the contiguous United States. Estuaries were included based on their current or future potential to provide habitat for fish species. It is possible that this list will expand or contract over time, as determined by the needs of PMEP.

It also synthesized information on juvenile nursery requirements of 15 focal species and whether juveniles of those species have been documented in these estuaries. It compiled this information in a report and associated geodatabase. 20120201 Citation: Cereghino, P., J. Toft, C. Simenstad, E. Iverson, S. Campbell, C. Behrens, J. Burke. 2012.

PMEP_EstuaryID unique identifier for each estuary included in the PMEP estuary inventory PMEP 1000 - 1999 ID range for ‘Salish Sea’ PMEP Region estuaries. These IDs were originally assigned in a general clock-wise order, from Points Roberts (1000) to Sail River (1165). PMEP 2000 - 2999 ID range for ‘Washington, Oregon, Northern California Coast’ PMEP Region estuaries. These IDs were originally assigned in a north to south order, from the Waatch River in Washington (2000) to the Bear River in Northern California (2109). PMEP 3000 - 3999 ID range for ‘Central California’ PMEP Region estuaries. These IDs were originally assigned in a north to south order within California, from McNutt Gulch (3000) to Jalama Creek (3106). PMEP 4000 - 4999 ID range for ‘Southern California Bight’ PMEP Region estuaries. These IDs were originally assigned in a north to south order within Southern California, from Canada de la Gaviota Creek (4000) to the Tijuana River (4060). PMEP Estuary_Name The name of the estuary. 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. PMEP These data are based on geographic names. PMEP_Region The PMEP Region (or ecoregion) which the estuary is located in. These areas were originally based on a dataset from The Nature Conservancy called "Marine Ecoregions of the World" (MEOW), but were refined based on the needs of PMEP. PMEP Salish Sea All watersheds draining into Salish Sea from within Washington State, along with the estuarine/marine areas of Puget Sound and the Strait of Juan de Fuca out to Cape Flattery within the U.S. Maritime Boundary. PMEP Washington, Oregon, Northern California Coast All Watershed Boundary Dataset (WBD) Subbasins draining into the Pacific Ocean from within Washington State (excluding the Salish Sea), Oregon and Northern California, from Cape Flattery (Washington) south to Bear River in Northern California. The exception to this standard is the inland extent of the Columbia River/Willamette River, which is based on WBD watersheds (HUC 10) overlapping the mapped estuary extent. The seaward extent of this region is based on a 200 meter depth contour. PMEP Central California All Watershed Boundary Dataset (WBD) Subbasins draining into the Pacific Ocean from within California, from Bear River in Northern California south to Jalama Creek, near Point Conception California. The exception to this standard is the inland extent of the Sacramento-San Joaquin Delta, which is based on WBD watersheds (HUC 10) overlapping the mapped estuary extent. The seaward extent of this region is based on a 200 meter depth contour. PMEP Southern California Bight All Watershed Boundary Dataset (WBD) Subbasins draining into the Pacific Ocean from within Southern California, from Jalama Creek, near Point Conceoption, south to the U.S.-Mexico border. The seaward extent of this region is based on a 200 meter depth contour. PMEP CMECS_Class Landscape-level geomorphological features from the coast to mid-ocean spreading centers. These large features can cross tectonic settings, and they can be delineated at a scale of 1:1,000,000 (or greater) using bathymetric maps and other remote sensing data. Each setting will normally contain a wide variety of the smaller geoform features. Coastal and Marine Ecological Classification Standard (CMECS), Federal Geographic Data Committee, 2012 Embayment/Bay A water body with some level of enclosure by land at different spatial scales. These can be wide, curving indentations in the coast, arms of the sea, or bodies of water almost surrounded by land. These features can be small—with considerable freshwater and terrestrial influence—or large and generally oceanic in character. CMECS Lagoonal Estuary This class of estuary tends to be shallow, highly enclosed, and have reduced exchange with the ocean. They often experience high evaporation, and they tend to be quiescent in terms of wind, current, and wave energy. Lagoonal estuaries usually have a very high surface in terms of wind, current, and wave energy. Lagoonal estuaries usually have a very high surface-to-volume ratio, a low-to-moderate watershed-to-water-area ratio, and can have a high wetland-to-water ratio. The flushing times tend to be long relative to riverine estuaries and embayments because the restricted exchange with the marine-end member and the reduced river input lengthen residence times. As such, there tends to be more benthic-pelagic interaction, enhanced by generally shallow bathymetry. Additionally, exchange with surrounding landscapes (often riparian wetland and palustrine systems) tends to be enhanced and more highly coupled than in other types of estuaries. Occasionally, a lagoon may be produced by the temporary sealing of a river estuary by a barrier. Such lagoons are usually seasonal and exist until the river breaches the barrier; these lagoons occur in regions of low or sporadic rainfall. CMECS Riverine Estuary This class of estuary tends to be linear and seasonally turbid (especially in upper reaches), and it can be subjected to high current speeds. These estuaries are sedimentary and depositional, so they may be associated with a delta, bar, barrier island, and other depositional features. These estuaries also tend to be highly flushed (with a wide and variable salinity range) and seasonally stratified. Riverine estuaries have moderate surface-to-volume ratios with a high watershed-to-water-area ratio—and they can have very high wetland-to-water-area ratios as well. These estuaries are often characterized by a V-shaped channel configuration and a salt wedge. CMECS Major River Delta The nearly flat, alluvial tract of land at the mouth of a river, which commonly forms a triangular or fan-shaped plain. It is crossed by many distributaries, and the delta is the result of sediment accumulation from the river. Deltas are distinguished from alluvial fans by their flatter slope. Examples of this feature type include the Mississippi Delta, the Nile Delta, and the Ganges Delta. All deltas are dynamic areas of mixed-water flow and salinity. CMECS Data_Source The organization, or organizations, whom provided spatial data for the estuary extent. PMEP OCMP Oregon Coastal Management Program (Oregon Department of Land Conservation and Development) PMEP PMEP Pacific Marine and Estuarine Fish Habitat Partnership PMEP System_Order This field links PMEP estuaries to the foundational report titled, "Nursery Functions of U.S. West Coast Estuaries: The State of Knowledge for Juveniles of Focal Invertebrate and Fish Species" (Hughes et al 2014). 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). Link to Report: http://research.pbsci.ucsc.edu/eeb/bbhughes/wp-content/uploads/2014/12/Hughes_etal_2014_NurseryFunction_TNC.pdf PMEP 1 303 Estuary_Hectares The area of the current and historical tidal wetlands of the estuary, in hectares, as calculated using Custom West Coast Albers projection. This value comes directly from the companion layer "PMEP West Coast USA Current and Historic Estuary Extent". Note that “mouth connection area” extents are not included in this value. PMEP These data are calculated based on the feature geometry of the companion PMEP Estuary Extent dataset.
