Vegetation grows abundantly on a once-flooded region of the Santa Ynez River. Located 5 ft adjacent from this picture is the actual flowing region of the stream. It is impressive to see the abrupt change in vegetation near stream environments.

The USGS maintains and monitors hundreds of streamgages across California, as well as across the Nation. Nearly all data collected by the USGS is made public and most in near real-time. Cities can use the data for flood mitigation and water supply.
