McNabney Marsh Shorebird Nesting Raft ProjectMuch of the suitable ground nesting habitat in McNabney Marsh has been lost in the 138-acre wetland. Because of subsidence (sinking of the marsh plain) and a constriction at the Union Pacific Railroad Bridge on Peyton Slough, McNabney Marsh doesn’t adequately drain when the tide gates are open. With these constraints, tide gate operations create challenges for ground-nesting shorebirds and…
The MVSD Western Pond Turtle StudyA baseline population study conducted in 2009 revealed that some 90 to 120 adult western pond turtles depend on habitat provided by MVSD’s Moorhen Marsh. This 21-acre freshwater wetland was constructed in the 1970s to provide valuable aquatic habitat for native fish and wildlife. The marsh receives 1.2 million gallons daily of advanced secondarily treated effluent as its primary water source.

The resulting Moorhen Marsh saved the District’s rate payers millions of dollars by eliminating the need for a deep water outfall while establishing a 21-acre habitat that benefits numerous aquatic and terrestrial species. Almost…
Wetlands Nesting Box ProjectMVSD has installed nesting boxes for the following bird species in the marsh system:
River Otter StudyUsing a series of cameras, we determined how river otters use the District’s wetlands and how many otters the wetlands support.
