Baby salmon are dying by the thousands in one California river, and an entire run of endangered salmon could be wiped out in another.

Human-made lakes that supply water to millions could reach historic lows.SAN FRANCISCO -- Fishermen who make their living off adult salmon, once they enter the Pacific Ocean, are sounding the alarm as blistering heat waves and extended drought in the U.S. West raise water temperatures and imperil fish from Idaho to California.

Hudson said he has considered retiring and selling his 40-foot boat because “it’s going to get worse from here.” When Lake Shasta was formed in the 1940s, it blocked access to the cool mountain streams where fish traditionally spawned. To ensure their survival, the U.S. government is required to maintain river temperatures below 56 degrees Fahrenheit in spawning habitat because salmon eggs generally can't withstand anything warmer.

As a result, the state has been trucking millions of salmon raised at hatcheries to the ocean each year, bypassing the perilous downstream journey. State and federal hatcheries take other extraordinary measures to preserve the decimated salmon stocks, such as maintaining a genetic bank to prevent inbreeding at hatcheries and releasing them at critical life stages, when they can recognize and return to the water where they were born.
