Santa Clara County. The preserve consists of the former Yacht Harbor area, the Palo Alto Airport, the Municipal Golf Course, the Duck Pond and public picnic area, the Baylands Athletic Center, the Sailing Station, the Lucy Evans Baylands Nature Interpretive Center, the Harriet Mundy Marsh and the Palo Alto Flood Basin. The flood basin is bordered by
Adobe Creek and
Matadero Creek and is maintained a couple feet below sea level in order to serve as a catchment basin in case of flooding in lower Palo Alto. At the northwest edge the Baylands extend past
San Francisquito Creek, although the creek used to flow into the Bay at the site of the former Yacht Club. In the late 1920s levees were constructed to re-route San Francisquito Creek away from its former mouth, to a sharp north turn for about half a mile, then to the northeast, before exiting to the Bay. Dredging of the former Yacht Club produced landfill for the filling of marshlands to construct the Palo Alto Airport and Municipal Golf Course. By 2004, filled areas such as the Palo Alto golf course and the
Palo Alto Airport had reduced the
