Name: Geoduck Tracts

Display Field: TRACT_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer contains geoduck TRACTS which are areas where geoduck aggregations have been observed between -18 ft MLLW and -70 ft MLLW, and are of interest for commercial harvest. This layer does not represent a comprehensive distribution of geoduck populations in Washington State. These geoduck tract polygons have updates as recently as 2016, including updating 97 tracts (of "commercial" status in 2005) from a nearshore biomass project from July of 2005. Tract boundary updates may be done yearly for those tracts surveyed each field season or those that underwent Washington Department of Health (DOH) classification revisions. Many geoduck tract polygons in this layer are older polygons "hand-fitted" with a digitizer and are intended to represent the general tract vicinity. Some tract polygons are fitted to NOAA water depth contours, with estimated "side" boundaries. Some tracts which have been biologically surveyed since 1994 have contour lines plotted by DNR or WDFW using GPS and fathometer equipment. Tract boundaries generally fall between the -18' MLLW and -70' MLLW contours, but tracts surveyed pre-1990 were only surveyed to the -60' MLLW contour. Some tract areas have restricted nearshore contours which range between -18' and -35' (MLLW) due to the presence of eelgrass beds and/or herring spawning habitat. Please request a current description of a tract from WDFW if interested in the exact descriptions and current restrictions. Boundaries are updated during the winter when WDFW summarizes surveys and receives survey information from tribal geoduck managers, and classification revsions from DOH. DOH should be consulted for current geoduck tract health classifications, openings and closures. An X-bed marks a location where geoducks have been reported, but the boundaries are not accurate as those tracts have never been surveyed.
