San Pablo Bay
San Pablo Bay is a tidal estuary that forms the northern extension of San Francisco Bay in the East Bay and North Bay regions of the San Francisco Bay Area in northern California. Most of the Bay is shallow; however, there is a deep water channel approximately in the middle of the bay, which allows access to major ports in Sacramento, Stockton, Benicia, and Martinez; and other smaller ports on the Sacramento–San Joaquin River Delta. Geography San Pablo Bay was named after Rancho San Pablo, a Spanish land grant given to colonial Alta California settlers in 1815, on the bay at the site of the present-day city of San Pablo. The bay is approximately across and has an area of approximately . The bay receives the waters of the Sacramento and San Joaquin rivers, via Suisun Bay and the Carquinez Strait on its northeast end, and it connects to the Pacific Ocean via the San Francisco Bay on its southern end. The bay is heavily silted from the contributions of the two rivers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peninsulas
A peninsula (; ) is a landform that extends from a mainland and is surrounded by water on most, but not all of its borders. A peninsula is also sometimes defined as a piece of land bordered by water on three of its sides. Peninsulas exist on all continents. The size of a peninsula can range from tiny to very large. The largest peninsula in the world is the Arabian Peninsula. Peninsulas form due to a variety of causes. Etymology Peninsula derives , which is translated as 'peninsula'. itself was derived , or together, 'almost an island'. The word entered English in the 16th century. Definitions A peninsula is usually defined as a piece of land surrounded on most, but not all sides, but is sometimes instead defined as a piece of land bordered by water on three of its sides. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napa River
The Napa River is a river approximately long in the U.S. state of California. It drains a famous wine-growing region called the Napa Valley, in the mountains north of the San Francisco Bay. Milliken Creek and Mt. Veeder watersheds are a few of its many tributaries. 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. Course The Napa River rises in northwestern Napa County just south of the summit of Mt. St. Helena in the Mayacamas Mountains of the California Coast Ranges. The source begins as seasonal Kimball Canyon Creek in Robert Louis Stevenson State Park at an elevation of which descends the southern slope of Mt. St. Helena to Kimball Canyon Dam. It flows south for 4 miles (6 km), entering the head of the slender Napa Valley north of Calistoga. In the valley, it flows southeast past Calistoga, St Helena, Rutherford, Oakville and through Napa, its head of navigation. Downstream ...

Petaluma River
The Petaluma River is a river in the California counties of Sonoma and Marin that becomes a tidal slough for most of its length. The headwaters are in the area southwest of Cotati. The flow is generally southward through Petaluma's old town, where the waterway becomes navigable, and then flows another through tidal marshes before emptying into the northwest corner of San Pablo Bay. History The word Petaluma may derive from the Miwok words ''pe’ta'', flat, and ''luma'', back. The Miwok people lived in Sonoma County for more than 2500 years. Petaluma was the name of a village on a low hill east of Petaluma creek and north east of the present day town of Petaluma. The first recorded exploration of the Petaluma River was by Captain Fernando Quiros in October, 1776. While other members of his Spanish expedition collected adobe and timber for the new Presidio of San Francisco and for the Mission San Francisco de Asís (Mission Dolores), Quiros and his sailors tried unsuccessfully ...

San Rafael Creek
San Rafael Creek is a watercourse in Marin County, California, United States that discharges to San Rafael Bay, a small embayment of the San Francisco Bay. The mouth of San Rafael Creek is a channelized estuary through an industrial area. San Rafael Creek has a designation under Federal Law Section 303(d) as impaired by diazinon, the principal pollutant causing impairment designations for streams discharging to San Pablo Bay, which is the northern arm of San Francisco Bay. In September 2007, the organization Save The Bay designated San Rafael Creek as one of the top ten "worst trash hot spot" waterways flowing into the San Francisco Bay. The channel portion of San Rafael Creek below the Grand Street Bridge is dredged on a regular maintenance schedule to keep the shallow draft channel navigable. Dredge spoils are disposed of at a site near Alcatraz Island. Most of the soils in the lower watershed are clays and bay mud, resulting in a low transmissivity of groundwater. Typical vert ...

Napa Sonoma Marsh
The Napa Sonoma Marsh is a wetland at the northern edge of San Pablo Bay, which is a northern arm of the San Francisco Bay in California, United States. This marsh has an area of 48,000 acres (194 km2), of which 13,000 acres (53 km2) are abandoned salt evaporation ponds. The United States Government has designated 13,000 acres (53 km2) in the Napa Sonoma Marsh as the San Pablo Bay National Wildlife Refuge. The marsh is fed by Sonoma Creek (which drains the Sonoma Valley), Tolay Creek (originating in the Tolay Lake basin), and the Napa River (which drains the Napa Valley). Although the marsh extends north as far as State Route 12, as a practical matter, most of the marsh is only accessible by boat. The marsh is a productive estuarine ecosystem providing habitat for a wide diversity of flora and fauna, including numerous rare and endangered species such as the California clapper rail and California freshwater shrimp. Because of its rich avafaunal content, the Napa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Valley (California)
The Central Valley is a broad, elongated, flat valley that dominates the interior of California. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast of the state. It covers approximately , about 11% of California's land area.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Carquinez Strait
The Carquinez Strait (; Spanish: ''Estrecho de Carquinez'') is a narrow tidal strait in Northern California. It is part of the tidal estuary of the Sacramento and the San Joaquin rivers as they drain into the San Francisco Bay. The strait is long and connects Suisun Bay, which receives the waters of the combined rivers, with San Pablo Bay, a northern extension of the San Francisco Bay. The strait formed in prehistoric times, near the close of one of the past ice ages, when the Central Valley was a vast inland lake. Melting ice from the Sierra Nevada raised the water level while seismic activity created a new outlet to the Pacific Ocean, draining the lake into the ocean and exposing the valley floors. History Andrei Sarna-Wojcicki, a geologist emeritus of the US Geological Survey (USGS), estimates that the Carquinez Strait was likely formed about 640,000 to 700,000 years ago, while much of modern California was emerging from an ice age.
