Folsom Lake is being drained, which helps some, while proving dangerous for others.
Sarah Johnston was watching her children play at the beach at Lake Natoma. She said she became protective of her children after hearing about the many recent drownings and increased water flows.
Federal water managers decided to release several thousand of cubic feet per second of water from dams and lakes upstream.
"My kids think you're being controlling, but they don't know that the farther they go out, the stronger the current is," Johnston said. "So I always have eyes on them at all times."
While parents and young kids have to be on higher alert because of the higher flows, fishermen are finding it beneficial.
"They're catching 10 to 20 fish a day," Fisherman's Warehouse owner, Alan Fong said.
The federal decision spawned from their concerns about endangered salmon. By flushing more water out, it increases the water temperature and decreases saline levels, which allows the fish to spawn and go upstream.
"The water is so warm and the conditions are so bad, they are flushing it so they can make it better for the fish," Fong said.
There is a law that requires water managers to prioritize so that animals do not become endangered or become extinct.
With the Nimbus Hatchery opening for salmon fishing last Thursday, combined with higher river flows, Fong said business is better. But not so much for humans, who are seemingly giving away what could be our precious water, for the fish.
"Cutting back, no watering lawns, try to take a shower in one song, all that, but they are releasing the water, anticipating the El Nino that is supposed to be coming this year, that's going to fill our lakes back up, I hope," Fong said.
