Cordelia Slough is a 10.8-mile-long (17.4 km) tidal watercourse which discharges to the Suisun Slough, which in turn empties into Grizzly Bay in Solano County, California. The Suisun Slough, fed by the Green River and Red Top Creek, provides a productive habitat for a diversity of aquatic flora and fauna. In particular steelhead migrate up Cordelia Slough to spawn in its two tributaries.
Cordelia Bay is known for its species biodiversity and also for prevalence of endangered species such as Sacramento splittail, Pogonichthys macrolepidotus and the Salt Marsh Harvest Mouse.
Some areas which drain into Cordelia Slough from the north are subject to development pressure from the expanding population of the San Francisco Bay Area; correspondingly, there are increasing risks of adverse water quality due to urban surface runoff from such new development.Cordelia Slough is considered a subarea of the Grizzly Island Wildlife Area, which is a State of California designated Wildlife Area.
The Guadalupe River mainstem is an urban, northward flowing 14 miles (23 km) river in California whose much longer headwater creeks originate in the Santa Cruz Mountains. The river mainstem now begins on the Santa Clara Valley floor when Los Alamitos Creek exits Lake Almaden and joins Guadalupe Creek just downstream of Coleman Road in San Jose, California. From here it flows north through San Jose, where it receives Los Gatos Creek, a major tributary. The Guadalupe River serves as the eastern boundary of the City of Santa Clara and the western boundary of Alviso, and after coursing through San José, it empties into south San Francisco Bay at the Alviso Slough.
The Napa River is a river approximately 55 miles (89 km) long in the U.S. state of California.

The river mouth is at Vallejo, where the intertidal zone of fresh and salt waters flow into the Carquinez Strait and the San Pablo Bay.
Stevens Creek is a creek in Santa Clara County, California.

It then continues north for 12.5 miles through Cupertino, Los Altos, Sunnyvale and Mountain View before emptying into the San Francisco Bay at the Whisman Slough, near Google's main campus.
Located in northern California the Suisun Marsh has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of the San Francisco Bay tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento and San Joaquin rivers between Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary.

Sonoma Creek is a 33.4-mile-long (53.8 km) stream in northern California. It is one of two principal drainages of southern Sonoma County, California, with headwaters rising in the rugged hills of Sugarloaf Ridge State Park and discharging to San Pablo Bay, the northern arm of San Francisco Bay. The watershed drained by Sonoma Creek is roughly equivalent to the wine region of Sonoma Valley, an area of about 170 square miles (440 km2). The State of California has designated the Sonoma Creek watershed as a “Critical Coastal Water Resource”. To the east of this generally rectangular watershed is the Napa River watershed, and to the west are the Petaluma River and Tolay Creek watersheds.

To the southeast, the area of Mission Peak Regional Preserve around Mission Peak is included. Agua Caliente, Canada del Aliso, Mission, Morrison, Sabercat, Vargas, and Washington creeks drain the area of the watershed. They drain into Laguna Creek and eventually Mud Slough.
