The U.S. Bureau of Reclamation has cut water releases from 1,100 cubic feet per second down to 500 feet.
"That has exposed some of the fall run salmon nests or 'redds' as they're called, r-e-d-d."
Tom Ghoring is with the Sacramento Water Forum.
On Capital Public Radio's Insight with Beth Ruyak, Ghoring said early surveys show that reductions, prompted by the dry winter, have left 15 percent of salmon nests or "redds" out of water.
"We know that exposing them is harmful to them. An exposed redd doesn't necessarily kill the eggs buried in the redd, but some of the nearby redds that are still underwater may be harmed so much that they could die."

Reclamation officials say reducing water flows into the American River will help conserve the water supply stored behind Folsom Dam.
Insight will have more about how the lack of rain is impacting the region, coming up at 9 a.m.
Another dry winter worries California rice farmers who are planning for this year's crop. The state's harvest was down nearly 25 percent last year. And, it's not just water that worries growers.
California’s water supply continues to diminish. The water content in the Sierra snowpack is the worst it’s been this time of year since 1991. Water conservation rates are equally dismal, dropping dramatically in January.
(AP) - The California Department of Water Resources says it will carry out the winter's third survey of the Sierra Nevada's snowpack.
What little bit of rain California received in December and February was just enough to help reservoir storage. The Department of Water Resources announced it will increase water deliveries through the State Water Project.
The US Bureau of Reclamation says most farmers south of the Sacramento-San Joaquin Delta will face a second year with no water from the Central Valley Project. Some farmers and cities may receive more.
