LAKE TAHOE (JUNE 29, 2021) –– With a paddle in one hand and a smartphone in the other, Emily Frey leaned over the hull of her kayak to snap a photo of an aquatic plant fragment floating on Tahoe’s deep blue waters. The photo is part of a report she submitted through the recently updated Citizen Science Tahoe app – a free, mobile-ready tool to crowdsource the collection of important scientific data at Lake Tahoe. In the midst of Tahoe’s busy summer season, and with the Fourth of July weekend approaching, the app update is well-timed to engage thousands of visitors in protecting Tahoe’s environment by quickly and easily reporting observations of aquatic invasive species, litter, water quality, algae, and more.

“With the Citizen Science Tahoe app, anyone can help Keep Tahoe Blue by taking a few minutes to report what you see at the lake,” said Frey, Citizen Science Program Coordinator for the League to Save Lake Tahoe. “While you’re paddling, hiking, or just lounging, pop open the app and report cloudy water, algae, invasive species, or litter on the beach. Tahoe scientists can’t have their eyes on the Lake at all times, but together we can.”

The app was developed by the UC Davis Tahoe Environmental Research Center (TERC) in 2015 to collect citizen science data as ground-truthing for Lake Tahoe’s real-time nearshore monitoring network. The League to Save Lake Tahoe (Keep Tahoe Blue) and Desert Research Institute (DRI) joined shortly after, adding a range of new surveys offered through the app. This summer, the team welcomed three additional partners: Clean Up the Lake, the Tahoe Water Suppliers Association, and Take Care Tahoe.

“The Citizen Science Tahoe app is growing, which is great news for Lake Tahoe and everyone who enjoys it,” said Heather Segale, Education and Outreach Director with the UC Davis Tahoe Environmental Research Center. “When ‘citizen scientist’ volunteers – visitors, locals, and everyone in between – submit data through the app, it advances our understanding of Lake Tahoe and informs research and advocacy efforts to better preserve this special place.”

With the addition of new partners, the app is even more useful. As Clean Up the Lake continues to protect Tahoe’s nearshore underwater environment, the organization is using the app to record litter found on the shoreline that may end up in the Lake if not picked up or reported. Take Care Tahoe community ambassadors are reporting issues they see at Tahoe’s most popular recreation areas, along with the interactions they have when helping visitors explore Tahoe’s outdoors responsibly. Visitors can use the app to find or report water refill stations thanks to the Tahoe Water Suppliers Association.

“Citizen science is accelerating our understanding of how and when Tahoe gets its water, whether as rain, snow or a wintry mix,” said Meghan Collins, Education Program Manager at the Desert Research Institute in Reno. “Millions of people depend on Tahoe for their water supply. The Citizen Science Tahoe app allows Tahoe-lovers to advance science and practice environmental stewardship all year long.”

The Citizen Science Tahoe app’s recent updates have made it more flexible for scientists, and quicker and easier for users. Visit citizensciencetahoe.org to get started. The upgraded app doesn’t need to be downloaded, and you don’t even need to use your cellular data. Simply wait to upload images once you’re connected to Wi-Fi. This makes the app easy to use in even the most remote locations.
