I have two feature classes 1: Watersheds 2: LongestFlowPaths. I've created a new feature layer from Watersheds with a SQL expression where "Shape_Area" >= 80km². I need to create a feature layer from the LongestFlowPaths that match the selected Watersheds where i.e. "Watersheds.HydroID" = "LongestFlowpaths.DrainID". and create a Feature Layer. Any assistance in being able to construct this would be appreciated.
