Join us for the 25th Annual Tahoe Truckee Snapshot Day!

Snapshot Day is an annual water quality monitoring event held each May. Groups of volunteers fan out across the Truckee River Watershed to take samples from creeks, streams, and lakes—including Lake Tahoe—to capture a snapshot of Tahoe’s water quality at a moment in time.

Volunteers of all ages and skill levels are encouraged to join us as we sample various sites around South Lake Tahoe for things like dissolved oxygen, pH, nutrients and more! Volunteers can sign up to join an existing team, create a team with family and friends, or be a Team Lead at their site. Team Leads will receive training prior to the event on how to most accurately collect the needed data for the day so they can guide their team of citizen scientists to success! To learn more about Snapshot Day and to view the 2024 map and Annual Snapshot Day Report, click here.
