90 Fun Facts About Lake Tahoe

The 1913 dam that controls Lake Tahoe's level stands at the lake's only outlet, in which town?

Tahoe City. The dam holds back only the top six feet of the lake, yet that thin layer is the largest reservoir in the whole Truckee River basin.

Lake Tahoe is the second-deepest lake in the United States, behind which other lake?

Crater Lake. Oregon's flooded volcano reaches 1,949 feet, about 300 more than Tahoe, yet Tahoe is still deeper than every one of the Great Lakes.

Which geological process created the basin that holds Lake Tahoe?

Faulting. The basin floor dropped between two rising blocks of crust, the main Sierra crest and the range to the east, so Tahoe is neither a blown-out volcano nor a river-cut valley.

Lake Tahoe is the largest lake of which kind in North America?

Alpine. Its surface sits 6,225 feet above the sea, yet the lake is so deep that its floor lies lower than the Nevada valley just across the mountains.

The Washoe people, Lake Tahoe's original inhabitants, traditionally gathered on its shores during which season?

Summer. Families fished and hunted by the lake in the warm months, then moved off to gather pine nuts in the fall and wintered in the lower valleys.

Which 1974 film shot its lakeside family-compound scenes at an estate on Lake Tahoe's west shore?

The Godfather Part II. The old Henry Kaiser estate played the Corleone compound, scene of the communion party and the attack on Michael, and Fredo's last fishing trip was filmed out on the lake.

Lake Tahoe holds enough water to cover the entire state of California to approximately what depth?

14 inches. That is about 39 trillion gallons, held in a lake only 22 miles long because its floor lies more than 1,600 feet down.

Lake Tahoe's first mapped name, Lake Bonpland, honoured a French botanist who explored South America with which naturalist?

Alexander von Humboldt. Aimé Bonpland travelled Latin America with him from 1799 to 1804, but his name never stuck to the lake, which maps soon called Bigler instead.

Approximately how old is Lake Tahoe?

2 million years. The basin itself is that old, though the outline visitors see today was only finished during the ice ages that came later.

In the 1910s, three attempts in Washington failed to give the Lake Tahoe Basin which protected status?

National park. Bills in 1912, 1913 and 1918 all failed, which left the shore open to the private building boom that followed the Second World War.

In 1955, Fred Rogers became the first person to do what at Lake Tahoe?

Swim its full length. The 29-year-old San Francisco bartender spent 19 hours in the water crossing from Kings Beach to the south shore, a swim a friend had called impossible.

Which interstate highway passes through Truckee, the usual freeway approach to Tahoe's north shore?

Interstate 80. It crosses the Sierra beside Donner Pass, named for the pioneer party that was snowbound there in the winter of 1846, before dropping to Truckee and the roads south to the lake.

What is the highest summit in the Lake Tahoe Basin?

Freel Peak. It belongs to the Carson Range rather than the main Sierra crest, yet it stands more than 1,000 feet higher than Mount Tallac.

What major environmental impact did the 1859 Comstock Lode discovery have on the Lake Tahoe Basin?

Large-scale deforestation. Loggers felled almost all of the basin's native forest between about 1860 and 1890 to timber the underground workings of the Comstock mines.

Which introduced fish, also known as mackinaw, is the prized big game fish of Tahoe's deep water?

Lake Trout. Despite the name it is a char, the largest of that family, and it was planted in Tahoe rather than being native to it.

John C. Fremont. He and his mapmaker glimpsed the lake from a peak to the south on 14 February 1844, in the middle of a desperate winter crossing of the Sierra.

Lava from which volcano dammed the Tahoe Basin's northern outlet and let the lake fill?

Mount Pluto. Its lava plugged the basin's outlet, and the water rose hundreds of feet above today's level before it found its present way out.

Emerald Bay lies in which corner of Lake Tahoe?

Southwest. The bay is so sheltered there that it sometimes freezes over in hard winters, something the open lake has never done.

Only the five Great Lakes hold more water than Lake Tahoe; which of them, the smallest by volume, comes closest?

Lake Erie. The shallowest Great Lake is only 210 feet deep at most, about an eighth of Tahoe's depth, but it spreads so wide that it still holds far more water.

Diving in Lake Tahoe is rated advanced because its altitude raises the risk of what?

At 6,225 feet the lower surface pressure shortens no-decompression limits, so diving Lake Tahoe raises the risk of decompression sickness and requires altitude-adjusted dive tables.

Which ski resort south of Lake Tahoe, reached by State Route 88, is known for deep snow and steep advanced terrain?

Kirkwood. It could open only in the early 1970s, once the state had begun ploughing Highway 88 through the winter.

Why does Lake Tahoe's main body never freeze over despite its 6,225-foot elevation?

Its huge thermal mass means so much water stores so much heat that the main body has never iced over, though sheltered bays such as Emerald Bay occasionally do.

What happens when a long drought drops Lake Tahoe below its natural rim?

Its outlet river stops flowing. Sixty-three streams feed Tahoe but only the Truckee drains it, so when the surface sinks under the 6,223-foot rim the river runs dry at the lake.

Apple. macOS Tahoe continued the company's habit of naming Mac software after California places, and gave the desktop a translucent 'Liquid Glass' look.

Which introduced salmon, a landlocked form that never goes to sea, is a popular catch in Tahoe?

Kokanee. They are landlocked sockeye, and the shrimp stocked in the 1960s to fatten them backfired by eating the lake's native water fleas almost to nothing.

Until 1934, Lake Tahoe's passenger steamers also carried which cargo on their daily circuit of the shore?

The mail. Letters were loaded each morning and dropped at the resort piers in turn, a round the side-wheeler Governor Stanford had cut to about eight hours in the 1870s.

Scandinavian. Lora Knight toured Scandinavia with her architect nephew for ideas, and the result, Vikingsholm, is rated among the finest examples of the style in the Americas.

Since the late 1960s, scientists have tracked Lake Tahoe's clarity by lowering what into the water until it disappears?

A white disk. The plate-sized Secchi disk stayed visible more than 100 feet down when readings began but only about 70 feet by the 2000s, with fine sediment from urban runoff largely to blame.

The 2007 Angora Fire, which destroyed more than 240 homes beside South Lake Tahoe, was started by what?

An illegal campfire. Investigators traced the blaze to a fire near Seneca Pond, where campfires were banned all year, and found no sign that it had been set on purpose.

Incline Village. It takes its name from the steep incline railway that once climbed 1,400 feet up the mountainside behind it.

Nevada's highest year-round Sierra pass, on State Route 431 above Tahoe's north-east shore, is named for which mountain?

Mount Rose. The road crests at 8,911 feet beside the peak, though the Mount Rose ski area it serves actually stands on neighbouring Slide Mountain.

Lake Tahoe is so wide that, seen from water level, the base of the far shore is hidden by what?

The curve of the Earth. Across the lake's 12-mile width the water bulges enough to hide about 100 feet of the opposite shore, and some 320 feet along its 22-mile length.

A landslide. The western rim of the basin collapsed into the water and left McKinney Bay as its scar; estimates of when range from about 12,000 to 50,000 years ago.

Lake Tahoe's beaches are the only known habitat of which rare plant?

Tahoe yellowcress (Rorippa subumbellata) grows only in the wet sand of Lake Tahoe's beaches between the low- and high-water marks, so lake levels decide its fate.

Each autumn, spawning salmon turn vermilion and run up which stream near South Lake Tahoe?

Taylor Creek. After spawning the salmon die, and their carcasses draw mink, bears and bald eagles to the stream each October.

Where does US Route 50 cross the Sierra crest on its way down to South Lake Tahoe?
