How the Seasons Affect Fishing on Shasta Lake
One reason Shasta Lake remains productive year-round is its ability to provide fish with the conditions they need during every season.
"Shasta Lake is a year-round fishery," guide Scott Caldwell says. "You can catch fish all year long."
The key is understanding how fish respond to changing water temperatures.
"In the wintertime, the water's very cold," Caldwell explains. "You can catch fish a lot more near the surface of the lake."
As spring transitions into summer, water temperatures begin to rise.
"Right now we're seeing temperatures anywhere from 70 to 76 degrees on the surface," Caldwell says. "What happens during this time is the fish start to migrate down deeper."
Cold-water species such as trout, salmon, and kokanee follow cooler water and baitfish into the depths.
"Most fish in lakes like to hang out in water that hovers around 50 to 55 degrees," Caldwell says. "That's kind of the honey zone."
During the hottest summer months, Caldwell often fishes for trout between 85 and 150 feet deep.
"The bait goes down, and the fish go with it," he says.
Bass behave differently.
"Bass don't mind the warm water," Caldwell explains. "Bass and sunfish don't seem to mind the warmer temperatures."
Fall brings another seasonal shift.
"As the temperature cools off, the fish come back up," Caldwell says.
Many fish also begin moving toward the lake's major tributaries.
"Shasta Lake has four big tributaries—the Sacramento, the McCloud, the Pit, and the Squaw," he says. "A lot of the fish go up those arms to do their deed in the fall."
Understanding these seasonal movements is one of the reasons local experience matters.
"You learn that by years of experience of fishing on the water," Caldwell says.
While conditions change dramatically throughout the year, fish remain catchable in every season.
"I've had good months every month," Caldwell says. "Just because it's freezing cold outside doesn't mean you can't have a good day on the lake."
Reading seasonal fish movement is the payoff of years on the water.
