Latham Slough

Map     Satellite

Latham Slough is a typical Delta slough, with open, shallow to medium-depth channels winding through low berms or islands containing freshwater-marsh vegetation.

In the more stable locations the large islands and levees have thickets of willow, Salix sp., occasionally mixed with buttonbush, Cephalanthus occidentalis, and stands of cottonwood, Populus fremontii. The freshwater marshes have particularly rich growths of Juncus sp., as well as tule, Scirpus sp. Isolated, but locally abundant, are growths of the Ludwigia repens and the exotic water-hyacinth, Eichhornia crassipes.

Though migratory waterfowl and, occasionally, fish occur here seasonally, most of the animal life is resident, with good populations of red-wing blackbirds, Agelaius phoeniceus, and other marsh birds, muskrats, Ondatra zibethica, and raccoons, Procyon lotor, among others. The endangered giant garter snake, Thamnophis couchi gigas, may occur here.

Integrity: The slough is bordered by levees, and the marsh areas are secondary to agriculture; thus they may be affected by dredging and other aspects of farming and levee maintenance.

Use: Research, educational, observational, light recreation. Portions private.
