Geoff Schladow, director of Tahoe Environmental Research Center, will give two presentations this month about what is going on beneath Tahoe’s surface.

The first is Nov. 5 at the North Tahoe Events Center in Kings Beach; the other is Nov. 6 at the Elks Point Fire Station in Round Hill. Both are from 6-7:30pm.

Schladow will share insights into Tahoe’s circulation pattern research, results of the NDEP-Tahoe Water Suppliers Association 2014 Risk Assessment Report, and water resource management implications.
