Millions of salmon being trucked to cooler waters amid California drought

The rivers that Chinook salmon use to migrate to the Pacific are drying up earlier than ever amid drought in California, so a massive operation is underway to transport the fish in tanker trucks.
Millions of young salmon are being trucked more than 100 miles to the San Francisco Bay to reach chillier waters, as severe drought engulfs much of California.
Ordinarily, the silver salmon are sent to the American River before heading toward the Pacific Ocean, but the river's heat is dangerous for the finned swimmers, Reuters reported. The high water temperatures and low water levels are a result of the ongoing drought plaguing the Golden State.

"We don't have any rain, so the water temperatures are going to be a little bit higher,” Feather River Hatchery manager Anna Kastner told AFP. “We're trying to give them the best chance possible."
Gov. Gavin Newsom declared a state of emergency in 41 of 58 counties in May as the drought parched much of the state and sent several major reservoirs well below normal capacity. The salmon haven’t embarked on a trip quite like this one since the 2014 drought.
The U.S. Drought Monitor estimates that more than 37 million people are living in drought-affected areas throughout the state. Conditions in about 94 percent of the state are considered severe, extreme or exceptional, according to the monitor.

Farmers in the state are fallowing their land, and government agencies are warning of fish kills on the Sacramento River. State regulators also started drafting an order to prevent farmers from pulling water from nearby rivers.
In 2014, researchers identified California’s drought as the worst in more than 1,000 years. That year, about 30 million Chinook salmon made their way from five fish hatcheries to waters that could lead them to the ocean, NPR reported.

Still, these trips could disrupt their natural behavior. Fish have an innate ability to “imprint,” or learn over time to identify their home water, so that they can return years later to spawn, NPR reported. A trip to new waters can be risky, but the last time these measures were enacted, an official in California’s department of fish and wildlife told NPR that the journey was worth it.
Mike Conroy, executive director of the Pacific Coast Federation of Fishermen's Associations, told Reuters that he is most concerned with the ramifications of the warming waters. He worries that every egg could die because of the rising temperatures.
For Kastner, there’s still lingering uncertainty.
"We want to make sure that we have the best available chance for this fish because we don't know what's going to happen,” Kastner said.
