The San Francisco Bay Delta is formed where the San Joaquin and Sacramento Rivers join in Northern California. The delta is an important resource for both fisherman and farmers. However, as with many rivers systems, far more water has been diverted from these rivers for irrigation than is needed for the farming, and the fish populations are being devastated. In this compelling video by the NRDC, we learn that salmon populations dropped from 1.4 million to 39,000 between 2002 and 2009, a 90% collapse. But action is being taken, and awareness of the problem is being raised, in part by videos such as this one above.
