Trapper Slough
Map SatelliteTrapper Slough is one of the better examples of standing water in the Delta. The vegetation is primarily that of a freshwater marsh, with Juncus, non-native Arundo, and Salix spp. dominating. In the quiet open water there are lush growths of the non-native water hyacinth, Eichhornia crassipes, and yellow water weed, Ludwigia peploides.
Muskrats, Ondatra zibethica, are common here and there is a wide variety of birds. Many migratory ducks use the slough as a resting place. Water clarity in the slough is considerably better than the typical Delta condition.
Integrity: Levees on both sides define the slough. As it is highly productive and adjacent to a highway, it is subject to heavy fishing pressure.
Use: Private
