The surface area draining to each debris flow traversal corridor is delineated from the confluence of the corridor with a fish-bearing stream. The delineated area defines a subbasin within the much larger 4th-field HUC analysis basin. Within each subbasis, the initiation sites for debris flows that can carry material to the fish-bearing stream at the subbasin mouth are mapped. These are the sediment source areas for that subbasin. Within each subbasin, the highest 33% of the mean annual deliveered sediment (source areas) is defined as the \"Sediment Source Areas\".<\/SPAN><\/P><\/DIV>", "extent":[[389059.4322583445,397005.02096187347],[690035.4297765397,697026.799428546]], "url":"https://gis.odf.oregon.gov/ags1/rest/services/Topography/DesignatedSedimentSourceArea/MapServer" }
