Be a part of citizen science at Lake Tahoe
with our new app!
Thanks to a newly updated "Citizen Science Tahoe" app that the League helped create along with the University of California, Davis' Tahoe Environmental Research Center (TERC) and the Desert Research Institute, it is easier than ever for League members and supporters to get involved in Lake Tahoe science and protection efforts.

The updated app now allows users to report on a host of Lake Tahoe beach conditions from algae to stormwater pollution. This spring and summer, users can participate in the League's "Eyes on the Lake" program and report sightings of aquatic invasive weeds like Eurasian watermilfoil or curlyleaf pondweed. This data feeds directly to the League’s team of experts who monitor and identify problem areas in Lake Tahoe, and then work to find innovative solutions to stop the spread of these invaders.

"Science is something that everyone can be a part of," said Zack Bradford, natural resources manager at the League. "Download the app and within minutes become part of a network of citizens working together to collect data and report significant findings that help us better understand and protect Lake Tahoe."

The new "Tahoe Citizen Science" app is available for download on the Apple App store, on Google Play and at citizensciencetahoe.org . Users of the original app will need to create a new account with email and password, or choose to report anonymously.

Lake Tahoe's clarity improved last year!
Lake Tahoe is known for its clear, blue, seemingly bottomless waters. Each year since 1968 researchers measure the Lake's famed clarity by lowering a white disk into the water and noting the depth at which it becomes invisible.

The League pays close attention to these measurements because our mission is to protect Lake Tahoe's water clarity and quality, for this and future generations. The annual report published by UC Davis researchers provides one valuable metric to gauge the health of the Lake.

The latest report found that the average clarity level in Lake Tahoe was 70.9 feet in 2018. That is a more than 10 foot increase from 2017, but is still a far cry from historic measurements of over 100 feet.

"We are thrilled to see Lake Tahoe's clarity improving from the all-time low of just 60 feet in 2017," said Darcie Goodman Collins, CEO of the League to Save Lake Tahoe. "These results encourage us to continue restoring critical habitat and improving our urban areas to keep pollution from entering our lake."

These latest results are encouraging and highlight the importance of continuing our work. The League, with the help of our members, works to protect Lake Tahoe from urban runoff and pollution through our Pipe Keepers citizen-science program and our transportation initiatives. We also restore critical meadow and marsh habitat with the help of our volunteers. These natural environments act as filters and further protect our Lake's clarity.
The time is now to help us protect the
Lake you love!

Volunteer Spotlight: Carolyn Robinson
Carolyn Robinson is standing on Kiva Beach beside Lake Tahoe. A group of five citizen-science volunteers are huddled around her as she directs them in various tasks to collect water quality data at their designated streamside location. The sky is cloudy but despite weather forecasts to the contrary no snow or rain is falling, and one of Carolyn’s team members is wading out into the cold stream water to collect a temperature reading. It comes back as 35 degrees Fahrenheit .

It is the 19 th Annual Snapshot Day in South Lake Tahoe. The event is one of the longest-running watershed monitoring events on the West Coast of the United States. On this one day in May each year, hundreds of volunteers disperse to collect data about the health of streams and lakes in the Tahoe-Truckee watershed, which includes Lake Tahoe.

Carolyn is once again a team leader. She has been a team leader for 14 years in a row, and the Soroptimist Club she is a member of has supported the event for over a decade. In more recent years the Soroptimist Club has donated funds to purchase new scientific equipment for citizen scientists to use on the day of the event.

"Having new equipment not only makes Snapshot Day more exciting for our citizen science volunteers, it also makes the data we collect more accurate," says Emily Frey, natural resources associate at the League. "Without the support of the Soroptimist Club over the years, this event wouldn’t have been successful."

Carolyn and the Soroptimist Club are deeply committed to protecting Lake Tahoe through volunteering and supporting collection of scientific data.

"I remember I read an article in the local paper about Snapshot Day and it just attracted my attention,” she says. What keeps her coming back year after year is the concept that an ordinary citizen like her who majored in English could go out and perform various experiments and collect samples. "The fact that the information we glean is used by various agencies to detect problems, it makes you feel so powerful in the efforts to Keep Tahoe Blue," she explained.

Prior to the event, Carolyn attended a team leader refresher training to re-familiarize herself with the correct ways to collect data during Snapshot Day. Then on the day of the event she was assigned a team of around five volunteers to help her successfully monitor a site, take photos and complete analyses.

Back on Kiva Beach, Carolyn and her team are staring closely at a timer as they wait for a small tablet to dissolve in a test tube sample of river water. A few minutes pass and their water sample does not change color, indicating that there is a low level of nitrogen present in it. This hands-on experience is what Carolyn loves most. "It’s just a fantastic day," she says. "The enthusiasm of all the people involved. You get caught up in it."
