Sacramento and San Joaquin Rivers in California listed endangered

The Sacramento and San Joaquin Rivers, two of the longest rivers in California, have been listed today as the USA's most endangered waterways, because of bad water management and really poor flood planning.

The American Rivers association chose these two rivers because if they collapse then 25 million Californians could be affected from lack of water supply, the captial could flood, and the freshwater delta where the two rivers meet would be damaged beyond repair.

The organisation took nominations from environmental groups and considered the value of the river to the people that need it and the threat it could pose if it failed, in order to make their decision. The state however said that the report did not give enough consideration to their efforts to restore the river's health in their report.
