The Delta Cross Channel gates were closed Tuesday around 10 a.m. to cut the connection between the Sacramento and Mokelumne rivers. The closure is an experiment that officials hope will increase the number of fall chinook salmon migrating from the ocean back to their spawning grounds along the Mokelumne.
With stronger currents coming from the Sacramento River where it connects with the Mokelumne, the salmon can become confused and get lost in the various channels. By cutting off the flow of stronger currents, it will be easier for salmon to migrate and eventually return to the hatchery.
