Laguna Creek Watershed
The Laguna Creek watershed consists of of land within northern California's Alameda County. The watershed drains the foothills of the Diablo Range south of Niles Canyon. 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. Water from winter and spring storms feed the creeks and the watershed. Natural springs along Mission Peak are also a source of water. Many of the creeks are dry when there is no rain. Background Morrison Creek and Mission Creek meet just before Mission Creek flows into Lake Elizabeth on the lake's southern shore. Much of what is now the Fremont Central Park was once the Stivers Lagoon. Water leaving the park divides between Laguna Creek and Irvington Creek. Irvington Creek is also known as Line G, or the Laguna Creek bypass flood cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Elizabeth (Fremont, California)
Lake Elizabeth, located in Central Park of Fremont, California, is a man made lake with a 2 mile walkway around the lake. When at average capacity, water rises to a depth of about seven feet.Average capacity ~= ~= 190 million U.S. gallons ~= 720 ML About Lake Elizabeth was named when it and the surrounding Central Park were dedicated to Fremont's sister city, Elizabeth, South Australia on March 22, 1969.

Valley Oak
''Quercus lobata'', commonly called the valley oak or roble, grows into the largest of California oaks. It is endemic to California, growing in interior valleys and foothills from Siskiyou County to San Diego County. Mature specimens may attain an age of up to 600 years. This deciduous oak requires year-round access to groundwater. Its thick, ridged bark is characteristic and resembles alligator hide. The valley oak's deeply lobed leaves assist in identification. Description The valley oak may surpass in height, with a sturdy trunk possibly exceeding in diameter. The "Henley Oak", in Covelo, California, is the tallest known valley oak, at . The branches have an irregular, spreading and arching appearance that produce a profound leafless silhouette in the clear winter sky. During autumn, the leaves turn a yellow to light orange color but become brown later in the season. In advancing age, the branches assume a drooping characteristic.

Leslie Salt Company
The Leslie Salt Company was a salt-producing company located in the San Francisco Bay Area, at the current locations of Newark, Hayward and other parts of the bay. Background They produced salt using salt evaporation ponds on the shores of the San Francisco Bay. By the 1940s, Leslie Salt under the dominant ownership of the Schilling family had become the largest private land owner in the Bay Area. By 1959, they were producing more than one million tons of salt annually, on over of bay salt ponds. They were purchased by Cargill in 1978.

San Francisco Bay Salt Ponds
The San Francisco Bay Salt Ponds are an approximately part of the San Francisco Bay that have been used as salt evaporation ponds since the California Gold Rush era. Most of the ponds were once wetlands in the cities of Redwood City, Newark, Hayward and other parts of the bay. Salt production goes back to when the Ohlone were the only people in the area. After the large influx of people to the area in the 1850s, industrial production began. At first, production was predominantly small family operations, but over time these were replaced by companies like the Oliver Salt Company in Mount Eden and Leslie Salt in Newark. Eventually, Cargill bought out the companies to become the dominant producer in the area. Since 2003, there has been a move to close the ponds and return the area to its natural state. This process may take as long as thirty years. Geography and fauna On the West Coast, the San Francisco Bay is one of two areas with the natural conditions from the sun and win ...

Slough (hydrology)
A slough ( or ) is a wetland, usually a swamp or shallow lake, often a backwater to a larger body of water. Water tends to be stagnant or may flow slowly on a seasonal basis. In North America, "slough" may refer to a side-channel from or feeding a river, or an inlet or natural channel only sporadically filled with water. An example of this is Finn Slough on the Fraser River, whose lower reaches have dozens of notable sloughs. Some sloughs, like Elkhorn Slough, used to be mouths of rivers, but have become stagnant because tectonic activity cut off the river's source. In the Sacramento River, Steamboat Slough was an alternate branch of the river, a preferred shortcut route for steamboats passing between Sacramento and San Francisco. Georgiana Slough was a steamboat route through the Sacramento–San Joaquin River Delta, from the Sacramento River to the San Joaquin River and Stockton. Plants and animals A slough, also called a tidal channel, is a channel in a wetland. Typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drawbridge, California
Drawbridge (formerly Saline City) is a ghost town with an abandoned railroad station located at the southern end of the San Francisco Bay, next to Station Island, now a part of the city of Fremont, California, United States. It is located on the Union Pacific Railroad south of downtown Fremont, at an elevation of 7 feet (2 m). Formerly used as a hunting village, it has been a ghost town since 1979 and is slowly sinking into the marshlands. It is now part of the Don Edwards San Francisco Bay National Wildlife Refuge and is illegal to visit. History Drawbridge was created by the narrow-gauge South Pacific Coast Railroad on Station Island in 1876 and consisted of one small cabin for the operator of the railroad's two drawbridges crossing Mud Slough and Coyote Creek to connect Newark with Alviso and San Jose. At one time 10 passenger trains stopped there per day, five going north and five going south. The drawbridges were removed long ago. The only path leading into Drawbrid ...

Debouch
In hydrology, a debouch (or debouche) is a place where runoff from a small, confined space discharges into a larger, broader body of water. The word is derived from the French verb ''déboucher'' (), which means "to unblock, to clear". The term also has a military usage. Geology In fluvial geomorphology, a debouch is a place where runoff from a small, confined space emerges into a larger, broader space. Common examples are when a stream runs into a river or when a river runs into an ocean. Debouching can generate massive amounts of sediment transport. When a narrow stream travels down a mountain pass into a basin, an alluvial fan will form from the mass deposit of the sediment. The four largest rivers (the Amazon, the Ganges-Brahmaputra, the Yangtze and the Yellow) are responsible for 20% of the global discharge of sediment in to the oceans by debouches. Geography In fluvial geography, a debouch is a place where a body of water pours forth from a narrow opening. Some examples ar ...
