California keeps one of the last true opening days in the West. The general trout opener is the last Saturday in April, it is an event in the eastern Sierra, and the rest of the state is a patchwork of district rules underneath it.
Every season we have verified in California
One block per rule, because a single species can be on two calendars in the same state depending on the water. The band under each heading is the legal season; the row under it is what our own data says the fish are doing.
Trout — General trout season, inland waters
The opener landed on April 25 in 2026, April 26 in 2025 and April 27 in 2024 — the last Saturday in April each time. Plenty of low-elevation waters are open all year underneath that rule, and district regulations vary enough that CDFW tells anglers to check the specific water rather than the date. The opener is a Sierra tradition more than a statewide switch.
- Limit
- 5 a day on most lakes, rivers and streams, with a 10-fish possession limit.

What the water is doing while the season is open
This is the part an agency page will not tell you. The temperature row above is the seasonal curve we use for the 19 of 58 California waters we track on a western two story profile, and it is why an opening date and a fishable date are not the same thing. A season that opens while the water is still in the forties is a legal invitation, not a biological one: the fish are there, they are just not eating on your schedule yet. Cross the legal band against the activity row before you book the day off.

The licence is a separate question
An open season is not permission to fish. California requires a licence from age 16, and residents pay from $64.54 against $174.14 for visitors. What a California licence costs and where to buy it →
Questions
When does fishing season open in California?
It depends on the species: trout opens april 25, 2026. Every date on this page was read off CDFW on 2026-09-14.
Do I need a licence to fish in California?
Yes. California requires a fishing licence from age 16, from $64.54 for residents. A season being open is not permission to fish: the licence is separate and so are the size and bag limits.
Are these California dates going to change?
Some of them, and the page says which. Dates written as a rule in the regulations are calculated here for 2026, so they follow the rule rather than going stale. Dates the agency sets each year are shown as exactly that, with no calendar band, because inventing one would be worse than leaving it empty.
