Upper San Leandro Reservoir
Upper San Leandro Reservoir is an artificial lake in Alameda County, California, Alameda County and Contra Costa County, California which provides water for the East Bay Municipal Utility District (EBMUD). It is impounded by the earth-filled San Leandro Dam on San Leandro Creek, located at the southeast end of the lake. Although it receives some runoff from its local watershed, most of the water is imported via the Mokelumne Aqueduct. The reservoir has a capacity of about , though its normal volume is about . The reservoir name includes "Upper" to distinguish it from Lake Chabot, several miles downstream, which was originally known as "Lower San Leandro Reservoir". Original dam The reservoir was originally formed in 1926 when the first San Leandro Dam was completed, and it was first filled by the Mokelumne Aqueduct in 1929. It inundated a long section of the San Leandro Creek valley, including the towns of Valle Vista and Redwood. The original dam was constructed between 1924 and ...

San Leandro, California
San Leandro ( Spanish for " St. Leander") is a city in Alameda County, California, United States. It is located in the East Bay of the San Francisco Bay Area; between Oakland to the northwest, and Ashland, Castro Valley, and Hayward to the southeast. The population was 91,008 as of the 2020 census.

Reservoirs In Contra Costa County, California
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the ...

Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent ex ...

Hydraulic Fill
Hydraulic fill is a means of selectively emplacing soil or other materials using a stream of water. It is also a term used to describe the materials thus emplaced. Gravity, coupled with velocity control, is used to effect the selected deposition of the material. Borrow pits containing suitable material are accessible at an elevation such that the earth can be sluiced to the fill after being washed from the bank by high-pressure nozzles. Hydraulic fill is likely to be the most economic method of construction. Even when the source material lacks sufficient elevation, it can be elevated to the sluice by a dredge pump. In the construction of a hydraulic fill dam, the edges of the dam are defined by low embankments or dykes which are built upward as the fill progresses. The sluices are carried parallel to, and just inside of, these dykes. The sluices discharge their water-earth mixture at intervals, the water fanning out and flowing towards the central pool which is maintained a ...

Lake Chabot
Lake Chabot is a man-made lake covering in Alameda County, California, United States. Part of the lake lies within Oakland city limits, but most of it lies in unincorporated Castro Valley, just east of San Leandro. It was formed by the damming of San Leandro Creek. The lake was completed in 1875 to serve as a primary source of water for the East Bay. The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Lake Chabot based on levels of mercury found in fish caught here. History The Lake Chabot dam was built in 1874-1875 as a primary source for water in the East Bay. At that time, the dam and reservoir were known simply as the San Leandro Reservoir. It was renamed Lower San Leandro Reservoir when another dam was built on the same creek upstream of the original lake, creating Upper San Leandro Reservoir. Chabot Dam was designated as a California Historic Civil Engineering Landmark by the American Society of Civil Engineers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mokelumne Aqueduct
The Mokelumne Aqueduct is a water conveyance system in central California, United States. The aqueduct is supplied by the Mokelumne River and provides water to 35 municipalities in the East Bay in the San Francisco Bay Area. The aqueduct and the associated dams, pipelines, treatment plants and hydroelectric system are owned and operated by the East Bay Municipal Utility District (EBMUD) and provide over 90 percent of the water used by the agency. The aqueduct is the sole water supply for about 1.4 million people in the East Bay. Under present water rights agreements, EBMUD can withdraw up to 325 million gallons (1,230,000 m3) per day, or per year, from the Mokelumne River. In addition, up to 98 million gallons (371,000 m3) per day or per year can be supplied via a branch from the Sacramento River. However, this supply is expected only to be used in the driest 35% of years. History In the early 20th century, due to a lack of reliable local water, Bay Area cities began to l ...
