Big Blue deserves better than a shoreline full of plastic. Whether we live here or drove up for a day on the lake, what we bring to the beach is ours to take home.
What the research shows
Microplastics are plastic pieces smaller than 5 millimeters. Sunlight, wind and waves can break larger plastic items into smaller fragments. UC Davis researchers have found microplastics in Lake Tahoe’s beach sand and water and are studying where those particles travel and collect.
The UC Davis Tahoe Environmental Research Center’s microplastics research explains the work. Finding plastic in the lake is reason to act, but it does not settle every question about its effects on freshwater wildlife or people. Those questions are still being studied.
Start with what we can carry out
Bring a refillable bottle. Keep loose wrappers and bags from blowing off the beach or boat. Take broken floats, fishing line and every bit of the day’s trash home. An overflowing bin is a reason to pack it out.
If you have time to lend a hand, ask a local cleanup team where help is needed. A little work on the shoreline beats walking past the same mess tomorrow.
Get involved with the lake cleanup
The Restoring the Lake Depths Foundation works on underwater cleanup. Removing larger litter matters, but a dive cleanup should not be described as filtering microplastics out of the whole lake.
Contact the foundation about volunteering or supporting its work. The team can tell you what is planned and where your help fits.
We get a lot from this place. Let’s give it some care in return.

Updated September 14, 2026: Research wording and foundation links have been corrected. An earlier version overstated what is known about health effects and described the cleanup work too broadly.
