The Drought's Hidden Victim: California's Native Fish

Last summer, a narrow, rock-rimmed stretch of the Sacramento River near here turned into a mass graveyard for baby salmon.

..

Upstream releases of water from Shasta Dam were so warm that virtually an entire generation of endangered winter-run Chinook was wiped out. The eggs never hatched, or if they did, the emerging young soon died.

..

A similar disaster could unfold this summer. And if the drought drags on for another year or two, wild populations of some of the state's most prized fish are likely to vanish.

..

"We're going to be losing most of our salmon and steelhead if things continue," said UC Davis professor emeritus Peter Moyle, a leading authority on California's native fish. Also in danger are the long-suffering delta smelt, whose numbers have plunged to what he called "the last of the last."

..

"It would be a major extinction event," Moyle warned.

..

The drought's toll on California has been measured mostly in terms of idled cropland, dried up domestic wells and brown lawns. Less visible but more devastating has been damage to native fish that struggle for survival in the best of times.

..

Four years of drought and the accompanying relaxation of environmental standards by state regulators have compounded the harm of dams and diversions that long ago thwarted fish migration and destroyed habitat.

..

Spawning winter-run Chinook would never choose to hang out on the outskirts of Redding on a day when the city baked in 111-degree heat. They would prefer to swim in the cold, spring-fed waters of the McCloud and other Sacramento tributaries to the north.

..

But for about 70 years, those historic spawning grounds have been out of salmon reach, blocked by the towering concrete face of Shasta and the buttresses of its smaller sibling, Keswick Dam.

..

"This is as far as fish can go on the Sacramento main stem," fishery biologist Ryan Revnak said as he steered his boat upriver toward Keswick, which regulates flows from Shasta's hydropower plant.

..

Revnak, who works for the Pacific States Marine Fisheries Commission, pointed out the gravel beds where the salmon built their nests, called redds. A female, close to death after laying her eggs, hovered in shallow water near the bank. A dead male, his procreative work also done, floated by.

..

Salmon eggs and emerging fry need cold water to survive. The river temperature shouldn't top 56 degrees. Last year in the spawning grounds below Keswick, it climbed above 62 degrees. Only 5% of the 2014 brood stock lived.
