One of the longest-running watershed monitoring events on the West Coast returns Saturday.
The 19th annual Snapshot Day runs from 9 a.m. to noon May 18.
A collaborative effort between the League to Save Lake Tahoe, the Nevada Division of Environmental Protection, the Tahoe Water Suppliers Association and the Truckee River Watershed Council, the event aims to collect data — a snapshot — about the health of streams and lakes in the Tahoe-Truckee watershed.
