What is the Delta?

This short video is intended to serve as an introduction to the Sacramento and San Joaquin Delta, and is the first in a series of four short videos highlighting USGS science in the San Francisco Bay and Sacramento-San Joaquin Delta Estuary. This video serves to orient the viewer to physical characteristics of the Delta, the challenges facing it, and the work the USGS is doing, in coordination with our partners, to understand and characterize the Delta ecosystem.
