Snapshot Day is a citizen science water quality monitoring event that takes place every May with the goal of connecting the community with its watershed. Volunteers fan out across the Truckee River Watershed to take water samples from creeks, streams and smaller lakes, as well as Lake Tahoe itself, to get a snapshot of one moment in time of the water quality of the Tahoe-Truckee watershed.
What do volunteers monitor for at Snapshot Day?
Volunteers field test streams for dissolved oxygen, total dissolved solids, pH and temperature; and collect water samples for laboratory analysis of turbidity, nutrients and bacteria. Teams also conduct thorough visual assessments of each monitoring site, watching for sources of pollution or disturbance. The information gathered by volunteers is compiled into long-term datasets on water quality conditions within the watershed. Snapshot Day also provides baseline data that can be used in ongoing and future environmental projects.
