"The GGSA is glad the Cross Channel Gates will be closed for 10 to 14 days because baby fall run king salmon are currently migrating from the Sacramento River to the ocean," said Golden Gate Salmon Association President Victor Gonella.

A fleet of 100 robots floated down the Sacramento River on Wednesday to demonstrate their ability to measure the pace of the river's flow and to navigate the delta's water.
