At the 8/26/2026 TRPA meeting, at least two public commenters
(one,
two)
raised concerns about the potential human health risks of smoke from glyphosate-treated vegetation, and a
Governing Board member mentioned the damage that
wildfire smoke
can cause to the lake.
In this August 2 interview,
Dr. Michelle Perro discussed concerns about smoke from glyphosate-treated vegetation.
Even low-intensity,
prescribed burns may pose risks to lake ecology and public health.
This issue should be studied further before any large-scale spraying in the ecologically sensitive and well-populated Lake Tahoe Basin.
“We're spraying a chemical on public land that no regulator has ever fully modeled for what happens when it burns.
Nobody has measured what's in that smoke. That's not science-based policy. That's an experiment on the public without consent."
— Michelle Perro, MD
1) The EPA Approval
Listen to the Environmental Working Group's perspective.
2) The Safety Study Retraction
Read about it in this
NY Times article.
3) What about the other species?
The EPA found that glyphosate is likely to injure or kill 93% of endangered species. Read about it in this
Center for Biological Diversity press release: PDF

Web.
Or watch this short video.
And then please ask: what about other species?
1) Water Monitoring Is Too Late
Consider
this testimony
from the July 17, 2026, meeting of the TRPA/MLWS Oversight Committee.
Water quality monitoring only detects contamination after the fact. And a mountain cannot be unsprayed.
2) Lesson From Lassen
This video by Protect Lassen
(north of Tahoe) reflects significant frustration with water monitoring
there. Note that Tahoe will not have aerial application, but ground applications will still occur across up to 3,600 acres of lake watershed.

3) Concerns About Transparency
USFS, TRPA, and Keep Tahoe Blue—what is the nature of their
working relationships, and what safeguards are in place to ensure independent decision-making?
Are there any funding, governance, or institutional dynamics that could affect independent
decision-making related to Basin protection? Why is monitoring being emphasized to the public
if monitoring only detects contamination after it has already occurred? These questions deserve clear answers.
1) Worker Welfare
Watch this short video
for a glimpse into the conditions to which workers may be exposed.
2) TRPA Oversight Committee
Listen to
this testimony
from the July 17, 2026, meeting of the TRPA/MLWS Oversight Committee for an overview of concerns about the Tahoe economy and
worker welfare.
Notes: 1) public comments reflect personal opinions, 2) legal recourse has been limited
but not eliminated by the decision, 3) this audio excerpt from the
TRPA Oversight meeting is reposted here to
document the public comment, support public-interest discussion, and make the relevant portion of
a public meeting easier to access.
3) Regarding Legal Recourse
For information about the June 2026 Supreme Court decision that limits certain legal recourse
if/when a worker gets sick, you can read this
NPR article

This song is free to share, and lyrics are free to take/use/improve in your own song.
NOTE: This song contains some exaggerations (e.g. nobody is going to wear hazmat suits, and glyphosate won't be visible in your hair) and speculation on potentials (wind picking up dust from the sprayed areas seems likely, but it's only a potential).
*This song may NOT be shared unless you include a note clarifying that certain lyrics are exaggerations and speculation, not literal.
COMING SOON
Song about the irony of needing a permit for yard projects, but not for spraying herbicides with soil/water/health risks across 2,400–3,600 acres of public forest near Lake Tahoe.

6225 = Elevation of Lake Tahoe
1962 = Year that Silent Spring was published
2026 = Year public awareness grew of plan to spray 2,400–3,600 acres of Tahoe forest with glyphosate and other synthetic herbicides.
Silent Spring is a landmark environmental science book that explores the dangers of pesticides and their harmful effects on wildlife, ecosystems, and human health. Its biologist author documented how indiscriminate pesticide use was poisoning water, soil, and wildlife — killing birds, fish, and insects — and challenged claims that pesticides were safe. The title "Silent Spring" refers to a future the author feared where spring would arrive without birdsong.
This song is coming. In the meantime, we've included a field recording of the Tahoe Caldor area recorded 6/10/2026.

July TRPA Oversight Committee meeting. Luckily, we have an audio recording — albeit low quality — of the meeting's important public comments.
Sorry for the quality.

On June 11, 2026, ProtectTahoe.com held its first "Town Hall" meeting at AleWorX at the Y. They allowed us to make an audio recording.
Two flyers were handed out, which we made scans of:
The Tahoe Regional Planning Agency (TRPA), which was created in large part to protect the Tahoe Basin,
has agreements called Memoranda of Understanding (MOUs) that exempt certain activities from permitting requirements,
such as routine work. One such agreement is with the Forest Service. A key unresolved question is whether
large-scale herbicide spraying by the Forest Service is exempt from TRPA review. At least four public comments
have raised this question:
1) TRPA Oversight Committee — 7/17/2026
This first known comment
was made at the July 17, 2026, meeting of the TRPA Oversight Committee in Stateline.
2) TRPA Oversight Committee — 8/20/2026
This second comment
was made at the August 20, 2026, meeting of the TRPA Oversight Committee in Carson City.
The written comment referenced in the audio can be found
here (PDF).
3) TRPA EIP Committee — 8/26/2026 #1
This third comment
was made at the August 26, 2026, meeting of the TRPA Environmental Improvement Program Committee in Stateline.
The written comment referenced in the audio can be found here (PDF).
4) TRPA EIP Committee — 8/26/2026 #2
This fourth comment
was made at the same meeting as Comment #3.

1) Digital Map
Although the Forest Service has said that herbicide will only be sprayed on a "subset of the area proposed for reforestation,"
we're not aware of any map showing where that subset is. However, we've created a digital map of the work area within which
the 2,400 to 3,600 acres lie, which should give you a general idea. You can view that map at
TahoeSprayAlert.org/map
2) Forest Service Maps
The Forest Service has PDF maps available here.
The PDF maps are harder to use, but they should be considered the authoritative source maps on which our digital map is based.
Note that they also do not show the exact spray area.
