Volunteers complete aquatic invasive plant survey on the Upper Truckee River
Citizen scientist volunteers, supported by staff from the League to Save Lake Tahoe, Tahoe Resource Conservation District and California State Parks, have wrapped up a three-year effort to survey the Upper Truckee River for aquatic invasive plants. This effort will help prevent the spread of harmful invasive species during major upcoming restoration projects along the river, Lake Tahoe’s largest tributary.

This multi-year survey, conducted through the League’s Eyes on the Lake Program, mapped the location of two aquatic invasive plants: curlyleaf pondweed and Eurasian watermilfoil. These aquatic invasives pose one of the greatest threats to Lake Tahoe’s delicate ecology.

We are happy to report that the last two years' surveys identified no aquatic invasive plants on the Upper Truckee from the Highway 50 overpass in South Lake Tahoe to the Highway 50 crossing in Meyers!

The first year’s survey, however, mapped a significant infestation near the mouth of the Upper Truckee River. The League will be working with the California Tahoe Conservancy to make sure this infestation is addressed in connection with restoration of the Upper Truckee Marsh.

“It’s great to see community members engaged and empowered through citizen science efforts like this,” said Jen Greenberg, associate environmental planner with the California Tahoe Conservancy. “This extensive survey will help inform multi-million dollar restoration projects, including the Upper Truckee Marsh restoration.”

Want to get involved in future aquatic invasive plant surveys? You can join Eyes on the Lake , the League's volunteer citizen science program to help prevent the spread of aquatic invasive plants in Lake Tahoe. Or you can d ownload the Citizen Science app and start reporting the presence of aquatic invasive plants today.

Celebrating our Citizen Scientists
On October 17, nearly one hundred community members came out to celebrate our local citizen scientists and their invaluable volunteer work in helping to Keep Tahoe Blue. It was an evening filled with education, food, music and good company, where the League’s core volunteers and citizen science program participants were recognized by the League and our partner organizations, including the City of South Lake Tahoe, Desert Research Institute, El Dorado County, Tahoe Resource Conservation District and UC Davis Tahoe Environmental Research Center . Many thanks to our sponsors, Himmel Haus and Soul Panda, for hosting.

In addition to a well-deserved night of fun, attendees discovered how data and observations collected by everyday people while out enjoying Lake Tahoe provide valuable information to both the agencies tasked with protecting the Lake and the top research institutes studying Tahoe. 

This event rounds out a big year for one of our citizen science programs, the Pipe Keepers, not only in monitoring pipe outfalls and whole networks of pipe infrastructure around the Lake, but in assisting in a ground-breaking study led by the Desert Research Institute that is investigating microplastics in Lake Tahoe. Event guests enjoyed a presentation from DRI researchers, where they shared their first-in-the-field findings about microplastics in the Lake .

Despite Lake Tahoe being one of the most studied lakes in the world, there is still a lot we don’t know about the “Jewel of the Sierra” and much to be done to preserve this important public treasure for generations to come. The climate crisis only increases the urgency to act now. Fortunately, millions of people visit Lake Tahoe every year, and with access to emerging citizen science programs, these volunteers are proving how visitors can be part of the solution by collecting valuable data while out enjoying the Lake.

Say hello to Emily, our Citizen Scientist guru!
Every once in a while, the League is delighted to spotlight one of our fantastic team members. This time around, we’d like to give much due credit to our Citizen Science Program Coordinator, Emily Frey, yet another member of our amazing staff of Lake Tahoe champions.

If you’ve volunteered at one of the League’s events, chances are you’ve crossed paths with Emily and seen firsthand her passion for Keeping Tahoe Blue.

Emily is responsible for the coordination of our Eyes on the Lake, Pipe Keepers and Snapshot Day citizen science programs. Emily has been with the League since 2018 and plays an integral role in the League's efforts to improve and protect the water quality and natural resources of Lake Tahoe and its watershed.

Congratulations Emily, we're lucky to have you on the team!
