Bodies of Water on Both Sides of Great Central Valley, California, USA

USA – October 7th, 2012

Several bodies of water can be seen on both sides of the Great Central Valley in the state of California, USA. On the right side of the image are Lake Tahoe (center, right) and Pyramid Lake (above, right). Both lakes are connected by the Truckee River, which is the sole outlet of Lake Tahoe and drains part of the high Sierra Nevada, emptying into Pyramid Lake in the Great Basin. Its waters are an important source of irrigation along its valley and adjacent valleys.

In the lower left quadrant is the San Francisco Bay, a shallow, productive estuary through which water draining from approximately forty percent of California, flowing in the Sacramento and San Joaquin rivers from the Sierra Nevada mountains, enters the Pacific Ocean.

Specifically, both rivers flow into Suisun Bay, which flows through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. However, the entire group of interconnected bays is often referred to as “San Francisco Bay”.

Lakes Near California-Nevada Border, USA

California, USA - March 10th, 2009

Arid tan terrain near the Nevada-California border, USA, gives way to the snow-covered Sierra Nevada mountains, which slope down into the fertile green San Joaquin Valley and finally to the Pacific Ocean.

The moutainous land in the upper right quadrant is interrupted by several dark blue lakes. At the very top is Pyramid Lake, an endorheic salt lake, approximately 188 square miles (487 km²) in area, in the Great Basin in the northwestern part of the US state of Nevada.

One of the largest lakes in the United States, it is located along the east side of the Virginia Mountains with a surface elevation of about 3,790 feet (1,155 m). It is fed by the Truckee River, which enters the lake from its southern end. It has no outlet, with water leaving only by evaporation, or sub-surface seepage. The salinity is approximately 1/6th of sea water.

The large body of water to the South is Lake Tahoe, in the Sierra Nevada mountains along the border between California and Nevada.

Freshwater Lake Tahoe is the largest alpine lake in the United States. Its depth is 514 m making it the USA’s second-deepest. The lake is known for the clarity of its water and the panorama of surrounding mountains on all sides.

Two smaller lakes are visible to the East: Walker Lake (above) and Mono Lake (below). The former is a natural lake, 50.3 mi² (130 km²) in area, in the Great Basin in western Nevada, along the eastern side of the Wassuk Range. It is 18 mi (29 km) long and 7 mi (11 km) wide. The lake is fed from the north by the Walker River and has no natural outlet except absorption and evaporation.

The latter, Mono Lake, is an alkaline and hypersaline lake in California that is a critical nesting habitat for several bird species and is an unusually productive ecosystem.
