Lake Tahoe from space (north is to the right)

The Lake Tahoe Basin was formed by a geologic block (normal) faulting about 2 million years ago. A geologic block fault is a fracture in the earth's crust causing blocks of land to move up or down. Uplifted blocks created the Carson Range on the east and the Sierra Nevada on the west. Down-dropped blocks (a graben) created the Lake Tahoe Basin in between.[1] Image File history File links Download high resolution version (3032x2064, 2138 KB) Source: [1] Image courtesy of the Image Analysis Laboratory, NASA Johnson Space Center. ...

Soils of the basin come primarily from andesitic volcanic rocks and granodiorite, with minor areas of metamorphic rock. Some of the valley bottoms and lower hill slopes are mantled with glacial moraines, or glacial outwash material derived from the parent rock. Cryopsamments, Cryumbrepts, rockland, rock outcrops and rubble and stony colluvium account for over 70% of the land area in the basin (see USA soil taxonomy).

Given the great depth of Lake Tahoe, and the locations of the normal faults within the deepest portions of the lake, modeling suggests that earthquakes on these faults can trigger tsunamis. Wave heights of these tsunamis are predicted to be on the order of 3 to 10 m in height, capable of traversing the lake in just a few minutes.[7] A massive collapse of the western edge of the basin that formed McKinney Bay around 50,000 years ago is thought to have generated tsunami/seiche wave with height approaching 100 m.[8] For other uses, see Tsunami (disambiguation). ...

Climate

Mean annual precipitation ranges from over 55 inches (1400 mm) in watersheds on the west side of the basin to about 26 inches (660 mm) near the lake on the east side of the basin. Most of the precipitation falls as snow between November and April, although rainstorms combined with rapid snowmelt account for the largest floods. There is a pronounced annual runoff of snowmelt in late spring and early summer, the timing of which varies from year to year. In some years, summertime monsoon storms from the Great Basin bring intense rainfall, especially to high elevations on the east side of the basin. For other uses, see Monsoon (disambiguation). ...

Ecology

Vegetation in the basin is dominated by a mixed conifer forest of Jeffrey pine (P. Jeffreyi), lodgepole pine (P. murrayana), white fir (Abies concolor), and red fir (A. magnifica). The basin also contains significant areas of wet meadows and riparian areas, dry meadows, brush fields (with Arctostaphylos and Ceanothus) and rock outcrop areas, especially at higher elevations. Ceanothus is capable of fixing nitrogen, but mountain alder (Alnus tenuifolia), which grows along many of the basin’s streams, springs and seeps, fixes far greater quantities, and contributes measurably to nitrate-N concentrations in some small streams.

Human history

Native peoples

The area around Lake Tahoe was originally inhabited by the Washoe tribe of Native Americans. Lake Tahoe was the center and heart of Washoe Indian territory, including the upper valleys of the Walker, Carson, and Truckee Rivers.

Exploration

Lt. John C. Frémont and Kit Carson were the first non-indigenous people to see Lake Tahoe, during Fremont's second exploratory expedition. John Calhoun Johnson, Sierra explorer and founder of "Johnson's Cutoff" (now Hwy 50), was the first white man to see Meeks Bay and from a peak above the lake he named "Fallen Leaf Lake, California" after his Indian guide. His first job in the west was in the government service, carrying the mail on snowshoes from Placerville to Nevada City, during which time he named the lake "Lake Bigler" in honor of California’s governor John Bigler. In 1853 William Eddy, the surveyor general of California, identified Tahoe as Lake Bigler. In 1862 the U.S. Department of the Interior first introduced the name Tahoe. Both names were used until well into the next century. The lake didn't receive its official and final designation as Lake Tahoe until 1945. John Charles Frémont (January 21, 1813 – July 13, 1890), was an American military officer, explorer, the first candidate of the Republican Party for the office of President of the United States, and the first presidential candidate of a major party to run on a platform in opposition to slavery. ...

Mining era

Upon discovery of gold in the South Fork of the American River in 1848, thousands of gold seekers going west passed near the basin on their way to the gold fields. European civilization first made its mark in the Lake Tahoe basin with the 1858 discovery of the Comstock Lode, a silver deposit just 15 miles (24 km) to the east in Virginia City, Nevada. From 1858 until about 1890, logging in the basin supplied large timbers to shore up the underground workings of the Comstock mines. The logging was so extensive that loggers cut down almost all of the native forest. In 1864, Tahoe City was founded as a resort community for Virginia City, the first recognition of the basin’s potential as a destination resort area.[10] GOLD refers to one of the following: GOLD (IEEE) is an IEEE program designed to garner more student members at the university level (Graduates of the Last Decade). ...

Development

Public appreciation of the Tahoe basin grew, and during the 1912, 1913, and 1918 congressional sessions, congressmen tried unsuccessfully to designate the basin as a national park. During the first half of the 20th century, development around the lake consisted of a few vacation homes. The post-World War II population and building boom, followed by construction of gambling casinos in the Nevada part of the basin during the mid-1950s, and completion of the interstate highway links for the 1960 Squaw Valley Olympics, resulted in a dramatic increase in development within the basin. From 1960 to 1980, the permanent residential population increased from about 10,000 to greater than 50,000, and the summer population grew from about 10,000 to about 90,000.[10] Since the 1980s, development has slowed due to controls on land use. // Dates of Sessions 1911-1913 Major Political Events New Mexico was admitted to the Union on 6 January 1912; Arizona was admitted on 14 February 1912, the last of the 48 contiguous states to join the Union. ...

Environmental issues

Water quality

In spite of land-use planning and export of treated sewage effluent from the basin, the lake is becoming increasingly eutrophic (having an excessive richness of nutrients), with primary productivity increasing by more than 5% annually, and clarity decreasing at an average rate of 0.25 meters per year. Fine sediment, much of it resulting from land disturbance in the basin, accounts for about half of the loss in clarity. Charles Goldman from UC Davis was directly responsible for prompting Tahoe officials to pump all sewage effluent from the basin when Tahoe was being greatly developed in the 1950s. Goldman made local officials understand that even treated sewage would greatly affect the water quality of Lake Tahoe.[12] Sewage is the mainly liquid waste containing some solids produced by humans which typically consists of washing water, faeces, urine, laundry waste and other material which goes down drains and toilets from households and industry. ... Eutrophication is apparent northern part of the Caspian Sea as imaged from orbit. ... This article or section cites very few or no references or sources. ... The University of California, Davis, commonly abbreviated to UC Davis or UCD is one of the ten University of California campuses. ...


Until the early 1980s, nutrient-limitation studies showed that primary productivity in the lake was nitrogen-limited. Now, after a half-century of accelerated nitrogen input (much of it from direct atmospheric deposition), the lake is phosphorus-limited. Because the volume of the lake is so large (156 km³) and its hydraulic residence time so long (about 650 years), its eutrophication may be essentially irreversible.


Lake Tahoe never freezes. Since 1970, it has mixed to a depth of at least 400 m a total of 6 or 7 times. Dissolved oxygen is relatively high from top to bottom.


Analysis of the temperature records in Lake Tahoe has shown that the lake warmed (between 1969 and 2002) at an average rate of 0.015 °C per year. The warming is caused primarily by increasing air temperatures, and secondarily by increasing downward long-wave radiation. The warming trend is reducing the frequency of deep mixing in the lake, and may have important effects on water clarity and nutrient cycling.

Ecosystem changes

Since the 1960s, the Lake's food web and zooplankton populations have undergone major changes. In 1963–65, opossum shrimp (Mysis relicta) were introduced to enhance the food supply for the introduced Kokanee salmon (Onchorhynchus nerka). The shrimp began feeding on the Lake's cladocerans (Daphnia and Bosmina), and their populations virtually disappeared by 1971. The shrimp provide a food resource for salmon and trout, but also compete with juvenile fish for zooplankton. Since the 1970s, the cladoceran populations have somewhat recovered, but not to former levels.


Lake Tahoe is actually a tributary watershed drainage element within the Truckee River Basin, and its sole outlet is the Truckee River, which continues on to discharge to Pyramid Lake. Because of the sensitivity of Truckee River water quality (involving two protected species, the cui-ui sucker fish and the Lahontan cutthroat trout), this drainage basin has been studied extensively. The primary investigations were stimulated by the U.S. Environmental Protection Agency, who funded the development of the DSSAM model to analyze water quality below Lake Tahoe.

Until recently, construction on the banks of the Lake had been largely under the control of wealthy real estate developers. Construction activities have resulted in a clouding of the lake's blue waters.

Since 1980, the Lake Tahoe Interagency Monitoring Program (LTIMP) has been measuring stream discharge and concentrations of nutrients and sediment in up to 10 tributary streams in the Lake Tahoe Basin, California-Nevada. The objectives of the LTIMP are to acquire and disseminate the water quality information necessary to support science-based environmental planning and decision making in the basin. The LTIMP is a cooperative program with support from 12 federal and state agencies with interests in the Tahoe Basin. This data set, together with more recently acquired data on urban runoff water quality, is being used by the Lahontan Regional Water Quality Control Board to develop a program (mandated by the Clean Water Act) to limit the flux of nutrients and fine sediment to the Lake.

Miscellaneous facts

  • Although Lake Tahoe is a natural lake, it is also used for water storage by the Truckee-Carson Irrigation District (TCID). The lake level is controlled by a dam at the lake's only outlet, the Truckee River, at Tahoe City. The dam only increases the lake's capacity by 732,000 acre feet (903,000,000 m³) and it only controls the top 6 feet (2 m) of the lake.
  • Vehicles Impact Lake Clarity - During peak season, cars and trucks driving in the Tahoe Basin account for 1 million vehicle miles per day, traveling on roads surrounding the 72-mile lake.
  • Fannette Island is the lake's only island. It is also protected by Emerald Bay State Park.
  • The North Shore features the Cal Neva Resort (once owned by Frank Sinatra) which has a marked state line running through it (even through its swimming pool).
  • Mark Twain accidentally started a forest fire in Lake Tahoe as described in Chapter XXIII of Roughing It. Twain used dramatic license in many of his books-whether he really started a fire is open to debate. He also remarked that due to its remarkable clarity and vivid blue hue, boating on the lake was akin to floating on the air.
  • In the motion picture The Godfather Part II, the Corleone family lived in a compound on the shores of the Nevada side of Lake Tahoe. In a famous scene from the final minutes of the film, Fredo Corleone is taken out onto the lake for a fishing trip, only to be executed for treachery, on the orders of his brother Michael (Al Pacino), who watches from the shore.
