The Peyton Slough Marsh Complex

McNabney and Moorhen Marshes

Mt. View Sanitary District’s (MVSD) treated effluent flows into a series of marshes, rather than a deep-water outfall as most treated wastewater does. These marshes, enhanced by the reclaimed effluent, are rich and diverse in wildlife and easily accessible to students, birders, researchers, and the general public. Biologists have identified 116 bird species 69 plant species, over 20 mammals and at least 34 species of aquatic invertebrates making their homes in the wetlands. At least 15 species of birds use the marsh complex for nesting.
