Fish Stocking Schedule vs. Confirmed Report: What California's Two Data Sources Mean
99.5% of California's stocking data here comes from a forward-looking schedule, not a confirmed report. Here's what that distinction actually means.
Almost all of the California stocking data on this site — 4,406 of 4,429 records, or 99.5% — comes from CDFW's Fish Planting Schedule, a forward-looking plan of intended stockings, not an after-the-fact confirmation. Only 23 records come from CDFW's separate "Recently Stocked Waters" feed, which reports what was actually planted.
Key takeaways
- California's stocking data on this site comes from two separate CDFW sources — the Fish Planting Schedule (ds2897) and Recently Stocked Waters (ds778) — and they're not the same kind of data.
- 4,406 of California's 4,429 records (99.5%) come from the Fish Planting Schedule — CDFW's own documentation describes it as "intended plans for fish plants," built to help anglers plan trips, not a guarantee of what already happened.
- Only 23 records come from Recently Stocked Waters, CDFW's after-the-fact confirmation feed, which by its own documentation reports "generalized" locations stocked in the current year and two preceding years.
- Counterintuitively, the schedule feed is more date-precise in this dataset — week-level for all 4,406 records — than the confirmed-report feed, which is year-level only for all 23 of its records.
- Every record on this site shows its specific source label, so you can always tell whether a given California stocking is a planned date or a confirmed one.
Two Different Kinds of "Stocked"
It's easy to assume every line in a stocking dataset means the same thing: a truck showed up and fish went in the water. California's own data shows that's not quite right. A planting *schedule* represents an agency's plan — built ahead of time to help anglers plan trips — and like any schedule, it's subject to real-world logistics. A *stocked waters* report, by contrast, documents water that has already been planted. Both are legitimate, useful data. They're just answering different questions.
California's Fish Planting Schedule (ds2897)
This is the source behind the overwhelming majority of California's data on this site: 4,406 records, every one of them precise to the week, spanning mid-2024 through mid-2026 in our dataset. CDFW describes this feed's purpose directly — its Annual Provisional Stocking Document "provides public notice of CDFW's intended plans for fish plants for the current year to assist anglers in planning future fishing and recreational trips," and the department maintains a dynamic, regularly updated public search tool built on the same underlying data.
Practically, that means a scheduled date is CDFW's plan for that water — genuinely useful for deciding which week to fish, but not a locked-in guarantee. Like any schedule, it can shift. Check closer to your trip date rather than treating a schedule set weeks out as final.
California's Recently Stocked Waters (ds778)
This feed is much smaller in our dataset — just 23 records — covering real, named waters including Crowley Lake, Florence Lake, Frenchman Reservoir, and Boca Reservoir. CDFW's own metadata describes each feature here as representing a "general location," not a specific stocking site — and notes that when a single water has multiple planting locations during a stocking event, only one is represented. In our data, none of these 23 records carry a specific date beyond the year, which is coarser than the week-level precision on the schedule feed above — a reminder that "confirmed" doesn't automatically mean "more detailed."
How to Tell Which One You're Looking At
Every stocking record on this site carries a source label naming exactly where it came from — CDFW's Fish Planting Schedule or its Recently Stocked Waters feed — so you're never guessing which kind of data you're looking at.

Frequently asked
Is California's fish stocking data a guarantee that a lake was actually stocked?
Not always. About 99.5% of California's records on this site come from CDFW's Fish Planting Schedule — a forward-looking plan meant to help anglers plan trips, not a confirmation that stocking already happened. A much smaller feed, Recently Stocked Waters, documents plants that CDFW has confirmed took place.
What's the difference between a "planting schedule" and a "stocked waters" report?
A planting schedule is an agency's plan for upcoming stockings, published in advance to help anglers plan trips. A stocked waters report documents plants that have already happened. California is the only state in this dataset where both kinds of source data exist side by side.
Why does California's schedule data show a specific week but the confirmed-report data only shows a year?
That's simply how CDFW's two source feeds are structured — the Fish Planting Schedule in our dataset carries week-level dates, while the smaller Recently Stocked Waters feed only reports a stocking year. It's a real, if counterintuitive, feature of the underlying data, not a data-entry error.
Where does CDFW publish its own fish planting schedule?
CDFW maintains a public, regularly updated search tool at its Fish Plants public portal, alongside an Annual Provisional Stocking Document that lays out its intended stocking plans for the year.
Can a scheduled stocking date change?
Yes. A scheduled date represents CDFW's plan at the time it was published, and like any schedule, real-world factors can shift it. Treat a schedule date as a strong guide for planning a trip, and check closer to your travel date for the latest information.
