World renowned for its crystal clear, azure water, Lake Tahoe
straddles the Nevada-California border. However, the lake’s
clarity has declined in the last 40 years due to accumulated
effects of development.
At 1,645 feet, Lake Tahoe is the second deepest lake in the
United States and the 10th deepest in the world. Lake Tahoe sits
6,225 feet above sea level, and is 22 miles long and 12 miles
wide.
Approximately 40 percent of the Tahoe Basin’s rain and snow fall
directly into the lake, contributing to Lake Tahoe’s legendary
clarity. The remaining precipitation drains through granitic
soils, which are relatively sterile and create a good filtering
system.
The lake’s vitality is threatened by several factors
including invasive species (trout and bass), stormwater
runoff and increasing temperatures as a part of ongoing climate
change. Meanwhile, drought conditions have led the lake to be the
driest it has been in a century.
Officials at Pyramid Lake say starting Oct. 1, watercraft
inspections will become mandatory for any craft using the lake.
The new regulation was approved by the Pyramid Lake Paiute
Tribal Council to strengthen protections against the invasive
mussels already seen in the Lake Tahoe area. The council says
the adaptability of the Golden Mussels makes them a serious
threat to the lake and its surrounding bodies of water.
Starting Oct. 1, all motorized and/or trailered watercraft must
be inspected prior to launch at the lake.
The California Tahoe Conservancy held a board meeting on
Thursday, Sept. 18, at Lake Tahoe Community College, but not
before a tour around two project sites. … The board’s first
stop at the Upper Truckee River Restoration demonstrated prior
efforts, which removed fill from wetlands, constructed a storm
water basin to improve water quality, and built new trails to
the river at the Elks Club site. … Restoring the Upper
Truckee River Watershed is a significant focus for the
conservancy due to its significance as the largest and most
environmentally consequential watershed draining to Lake Tahoe.
On Wednesday, the Tahoe City Public Utility District celebrated
the Grand Opening of the West Lake Tahoe Regional Water
Treatment Plant. … The plant can currently deliver one
million gallons of water per day and may be further expanded to
reach more customers from Tahoma to Timberland. The utility
district stated that the approximately $30 million project was
made possible by grant funding as well as a loan from the CA
State Water Resources Control Board.
Keep Tahoe Blue, The Tyre Collective, and Desert Research
Institute (DRI) announced a groundbreaking collaboration with
the Emerald Bay Shuttle and its operator, Downtowner, that
brings together science, technology, and alternative
transportation to protect Lake Tahoe’s world-renowned water
clarity. … The pilot program employs The Tyre
Collective’s proprietary technology — discrete, compact devices
affixed to a vehicle’s undercarriage — to capture harmful tire
wear particles directly at the wheel.
The cobalt waters of Lake Tahoe have long captivated the
public, helping drive the area’s massive tourism industry and
even attracting urban legends about what lies in the cold,
shadowy depths. Theories have ranged from an aquatic creature
named Tessie to perfectly preserved bodies dumped by the mafia
decades ago. This week, Tahoe enthusiasts got to take in a much
rarer view of the lake. On Friday, thousands of people tuned in
to see a remotely operated vehicle travel down to the bottom of
one of the country’s deepest lakes, at more than 1,500ft below
the water.
The Tahoe Fund will livestream the journey of Deep Emerald, a
custom-built remotely operated vehicle as it explores Lake
Tahoe’s 1,570-foot depths. This event is a partnership between
the Tahoe Fund and the Restoring the Lake Depths Foundation,
allowing anyone to witness the ROV’s expedition on Friday
through the Tahoe Fund’s website starting at 9:30 a.m. The two
organizations say the event is the first-ever livestream to
show the bottom of the lake.
It was a gorgeous June Saturday on Lake Tahoe, but the day
turned stormy in minutes when a torrent of winds whipped up
choppy waters that terrified boaters. Eight people died. The
Times looked at videos, radar and satellite imagery, and
interviewed over 30 people, including meteorologists, local
officials and boaters who were on the lake that day. The
investigation revealed a rare set of circumstances that led to
the unexpectedly dangerous day.
Lake Tahoe’s clear waters are benefiting from a record-breaking
effort to reduce pollution, according to a new report from
California and Nevada. The report by the Lahontan Regional
Water Quality Control Board found that an estimated 727,000
pounds of fine sediment; more than 5,800 pounds of nitrogen;
and nearly 2,100 pounds of phosphorus were prevented from
reaching the lake in 2024 — all annual record highs since the
program began tracking these statistics in 2016. These
pollutants can fuel algae growth and harm the lake’s clarity.
On average, more than 60 percent of
California’s developed water supply originates in the Sierra
Nevada and the southern spur of the Cascade Range. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.
This tour ventured into the Sierra to examine water issues
that happen upstream but have dramatic impacts downstream and
throughout the state.
Sixty percent of California’s developed water supply
originates high in the Sierra Nevada mountains. Our water
supply is largely dependent on the health of our Sierra forests,
which are suffering from ecosystem degradation, drought,
wildfires and widespread tree mortality.

water issues that happen upstream but have dramatic impacts
downstream and throughout the state.

Lake
Tahoe, the iconic high Sierra water body that straddles
California and Nevada, has sat for more than 10,000 years at the
heart of the Washoe tribe’s territory. In fact, the name Tahoe
came from the tribal word dá’aw, meaning lake.
The lake’s English name was the source of debate for about 100
years after it was first “discovered” in 1844 by people of
European descent when Gen. John C. Fremont’s expedition made its
way into the region. Not long after, a man who carried mail on
snowshoes from Placerville to Nevada City named it Lake Bigler in
honor of John Bigler, who served as California’s third governor.
But because Bigler was an ardent secessionist, the federal
Interior Department during the Civil War introduced the name
Tahoe in 1862. Meanwhile, California kept it as Lake Bigler and
didn’t officially recognize the name as Lake Tahoe until 1945.

definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado

Lake Tahoe is one of the world’s most beautiful yet vulnerable
lakes. Renowned for its remarkable clarity, Tahoe straddles the
Nevada-California border, stretching 22 miles long and 12 miles
wide in a granitic bowl high in the Sierra Nevada.
Tahoe sits 6,225 feet above sea level. Its deepest point is 1,645
feet, making it the second-deepest lake in the nation, after
Oregon’s Crater Lake, and the tenth deepest in the world.
Lake Tahoe is one of the Sierra Nevada’s crown jewels, renowned
for its breathtaking clarity. The high-altitude, clear blue lake
and its surrounding basin, which lie on the California-Nevada
state line, is a spectacular natural resource that provides
environmental, economic, recreational and aesthetic benefits.
