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
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
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.
In many American communities, rivers irrigate the farms that
feed families, quench people’s thirst—rivers are the source of
more than two-thirds of the drinking water in the U.S.—sustain
wildlife habitat, and provide an economic boost for
communities. Yet only a very small portion of those waterways
are protected from threats ranging from pollution to damming,
which would wreck the water’s natural flow.
… California’s Regional Water Quality Control Boards
have authority to designate ONRWs but to date have done so for
only two bodies of water: Lake Tahoe and Mono Lake. However,
the state did initiate an analysis of the Smith River as
an ONRW but has not completed the effort. The Smith is a
Pacific salmon stronghold.
Lake Tahoe is known for its mesmerizing clear, blue water.
But there are multiple threats to the lake that may
someday change the color and worse, downgrade the quality
of the water. Some of the most difficult of these threats to
address are invasive species, specifically two types of
aquatic plants that are not native and are moving from an area
of the lake known as the Tahoe Keys into Lake Tahoe
itself. The plants are Eurasian watermilfoil and
Emerging technologies will be at the forefront of this summer’s
launch of the ten-year, multi-agency effort to address aquatic
invasive species (AIS) as laid out in The Lake Tahoe Region
Invasive Species Action Agenda. Published in late 2019,
Phase I of the Action Agenda aims to aggressively treat and
control-test mitigation measures of AIS in the Tahoe Keys from
2021-2025. The environmental assessment and control-testing
outcomes from Phase I will then guide the implementation of
Phase II’s reduction and eradication measures from 2026-2030.
Aquatic invasive species offer a complex and unique set of
challenges for experts looking to find the best mitigation
strategy for their Action Agenda.
The South Tahoe Public Utility District is seeking input as
they update the groundwater management plan for the greater
South Lake Tahoe area. Groundwater is the primary source of
drinking water for more than 90% of the public and private
water systems located throughout this area. Seeking input from
beneficial uses and users of groundwater ensures the region’s

The Nevada Division of Environmental Protection announced that
$1 million in Clean Water Act grant funds provided by the U.S
Environmental Protection Agency will be used to complete 11
projects, including two in Lake Tahoe, to reduce “nonpoint
source pollution” and improve water quality across the state.
In the Tahoe Keys—a neighborhood of houses and artificial
lagoons with easy boat access to Lake Tahoe, one of America’s
least polluted lakes—the water is not blue but a murky mass of
green, filled with invasive weeds. Dogs have died from swimming
in the canals, which is prone to toxic algae blooms. Activists
want to wall the Keys off from the lake. The neighborhood
association is proposing to tackle the problem with herbicides,
which have never been used before in Lake Tahoe.
Crews began work this month in the marsh system of Taylor and
Tallac creeks in the Southwest portion of the Tahoe Basin to
remove aquatic invasive plants from an abundant and impacted
marsh ecosystem, the Tahoe Regional Planning Agency announced.

A first-of-its-kind study in California has laid bare the
staggering scale of pollution from plastic microfibers in
synthetic clothing – one of the most widespread, yet largely
invisible, forms of plastic waste. The report, whose findings
were revealed exclusively by the Guardian, found that in 2019
an estimated 4,000 metric tons – or 13.3 quadrillion fibers –
were released into California’s natural environment.

Volunteer citizen scientists working with the League to Save
Lake Tahoe conducted surveys of Donner and Spooner lakes to
detect aquatic invasive species, and restored native wetland
habitat in Johnson Meadow in September. Both efforts are aimed
at preserving the Tahoe-Truckee region’s unique ecology.
U.S. and tribal officials are celebrating completion of a $34
million fish bypass system at a Nevada dam that will allow a
threatened trout species to return to some of its native
spawning grounds for the first time in more than a century.
Construction of the side channel with fish-friendly screens is
a major step toward someday enabling Lahontan cutthroat trout
to make the same 100-mile journey — from a desert lake
northeast of Reno to Lake Tahoe atop the Sierra — that they did
before the dam was built in 1905.
What is all this smoke from wildfires doing to Lake Tahoe
itself? I called Dr. Geoffrey Schladow, director of the UC
Davis Tahoe Environmental Research Center, to find out.
Schladow is part of a group of scientists that measure and
track Tahoe’s clarity. … To answer my question, Schladow gave
a standard scientist’s response: It’s complicated.
Groups in the Tahoe Basin are using new technology to fight
invasive species and decreasing lake clarity. Researchers at
University of Nevada, Reno and Tahoe Regional Planning Agency
have been testing a UV light equipped vessel to control aquatic

Growing up in Northern California, I spent my summers visiting
the Tahoe Basin, learning to appreciate the natural
environment. Those summers were filled with trips into the
remarkable backcountry, biking around the lake’s 72-mile
perimeter and swimming in its clear, blue water. It’s those
memories that I would carry with me each year into the Lake
The snow along the mountains of Nevada’s Great Basin trickle
down when the spring turns into summer. This produces a flurry
of wildlife and natural resources in our area ponds, rivers,

would collect thousands of trout from the late 1800’s to the
1900’s. Eventually, this would cause the near extinction of our
state’s native species, the Lahontan cutthroat trout.

beaches and chic coastal towns, the Golden State is also home
to many pristine lakes and reservoirs where visitors can soak
up the sun and cool off. CNN Travel takes a quick and
refreshing look at some of the best lakes in California.
Lake Tahoe’s fluctuating clarity got worse last year during an
especially cold and wet winter as sedimentation, algae growth
and a tiny invasive shrimp continued to pose restoration
challenges for the famed clear water of the mountain lake
straddling the California-Nevada line.
When it was measured last year, the clarity of the lake was
about 80 feet. … But, consider this, about 20 years ago, the
clarity of lake was 100 feet. That’s the trend scientists are
trying to reverse.
This new technology is an improvement on the existing bubble

Over the next 3 weeks a group of League to Save Lake Tahoe
citizen scientists will outfit their clothes driers with
special filters to capture particles from dryer vent emissions.
Dr. Monica Arienzo of the Desert Research Institute explained
that unexpected results from a remote snow sample led to a
curiosity in dryer emissions.
In June 2018, scientists first noticed that aspen trees around
the basin were looking more defoliated than usual… “It was
concerning because, from a landscape diversity perspective,
aspens are so priceless in terms of what they contribute up
here,” said Will Richardson, executive director of the Tahoe
Institute for Natural Science.
The Upper Truckee Marsh in South Lake Tahoe once covered 1,600
acres and is now around 600 acres. It suffered in recent
decades because of cattle ranching, channelizing of the river
and the development of a neighborhood called the Tahoe Keys in
the 1950s and ’60s.
The historic lighthouse at Rubicon Point was born out of
organized advocacy work in the early 1900s. The Lake Tahoe
Protective Association formed in response to a proposal to cut
the rim of Lake Tahoe at the Truckee River. The proposal was
floated by the Truckee River General Electric Company in 1912
as a means to keep water flowing out of Tahoe even when the
lake level dipped too low.
Clarity in Tahoe, the alpine jewel of Northern California known
for its crystaline waters, was measured to a depth of 62.7 feet
in 2019. That’s down nearly 8 feet from the year before, when
clarity clocked in at 70.9 feet, and stands as the
second-lowest figure since record-keeping began in 1968.
Unlike in recent years when researchers were able to point to a
dominant factor affecting lake clarity like drought or
higher-than-average precipitation, 2019 saw a range of
influences on Tahoe, including lake mixing for the first time
in several years, sediment, algae, and climate warming. Those
factors, according to the University of California, Davis Tahoe
Environmental Research Center, combined to cause a roughly
8-foot decrease in average clarity from the previous year’s
The American Water Works Association has recognized the Tahoe

During the past 107 years, daily air temperatures measured in
Tahoe City have increased. The average daily maximum
temperature has risen by 2.25 degrees Fahrenheit, and the
average daily minimum temperature has risen by 4.43 degrees.
According to the report, the number of days when air
temperatures averaged below freezing has declined by about 30
days since 1911, though year-to-year variability is high.
Water is indeed the most precious natural resource in the arid
West and from that perspective it should come as no surprise
that water-rights issues on Lake Tahoe and Truckee River have
been at the center of negotiation and controversy since
pioneers first settled the region.
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.
Participants joined us as we guided them on a virtual journey into the foothills and the mountains to examine water issues that happen upstream but have dramatic impacts downstream and throughout the state.
Good news, just in time for Memorial Day Weekend: The clarity
of the famed, cobalt-blue waters of Lake Tahoe improved
dramatically last year, with visibility increasing 10 feet from
the year before, a study released Thursday by scientists at UC
Davis found. The jump is the largest annual improvement in 50
years, since measurements at the iconic Sierra Nevada lake
began in 1968.
For the third year in a row, Lake Tahoe is expected to fill.
This is noteworthy for the sixth-largest lake in the United
States that flirted with record-low levels amid a five-year
drought that ended in 2017.
This bill calls for $150M in funding over the next ten years

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.
The U.S. Army Corps of Engineers has reached an agreement with
the Tahoe Regional Planning Agency to provide $1 million in
federal funding to help combat invasive aquatic species that

Lake Tahoe’s water level has remained high and the Tahoe City
dam has been releasing more water down the Truckee River. But
for one lakefront community, it’s not happening fast enough.
Lake Tahoe’s cold, deep waters have long been the source of

Lake Tahoe’s famously clear waters continue to warm, and the
surrounding forests face dire threats due to drought, disease
and insects, according to the annual Tahoe State of the Lake
report by researchers at UC Davis. The second deepest lake in
the United States after Crater Lake, Lake Tahoe has warmed by
half a degree Fahrenheit each year for the past four years — 14
times faster than the historic rate, the report said.
Tahoe is brimming, nearly full for the first time in 11 years,
and stunningly beautiful in all its blue-water glory.

been relying on citizen science to monitor drainage sites and
collect water samples around the lake.
As of Tuesday afternoon, lake level was at 6,228.18 feet, just
.92 inches from Lake Tahoe’s legal limit of 6,229.1 feet. The
Upper Truckee River was just shy of 8 ½ feet — about 2 feet
from flood stage.
UC Davis scientists from the Tahoe Environmental Research
Center have been measuring the lake’s water clarity for nearly
50 years. The latest data shows a big drop in how far down the
