Rainbow Trout Stocking: What 4 States’ Records Show
Rainbow trout dominate the stocking records in four states covered here. See where the reported plants cluster, what the counts mean, and how to check a water before you go.
Across Utah, Montana, Washington, and New York, StockedWaters indexes 201,069 rainbow-trout stocking records at 4,532 waters. Those records span 1924–2026 and total about 1.08 billion reported fish, making rainbow trout the most broadly recorded stocked species in this four-state snapshot.
Key takeaways
- Rainbow trout appear in all four live state datasets that report them: Utah, Montana, Washington, and New York.
- Montana has the most reported fish in this snapshot; Utah has the most stocking-event records after Montana.
- A reported plant helps narrow a trip plan, but the current state report and local regulations are the final check.
Which states stock rainbow trout?
Rainbow trout appear in the public stocking records for Utah, Montana, Washington and New York. The useful question is not simply whether a state stocks rainbows, but which water received a reported plant, at what size, and on what date precision.
The figures are a reproducible snapshot of the agency records indexed by StockedWaters. A record is a reported stocking event; it is not a promise that fish remain in a water today.
Rainbow trout stocking by state: the record snapshot
The state totals below count published records and distinct named waters, not an estimate of a living fish population.
- Utah — 78,355 records across 541 waters; 308,517,501 reported fish.
- Montana — 64,512 records across 1,951 waters; 486,856,189 reported fish.
- Washington — 52,036 records across 1,634 waters; 271,924,189 reported fish.
- New York — 6,166 records across 423 waters; 9,698,010 reported fish.
How to compare rainbow trout stocking records honestly
The event total, distinct-water total, and reported-fish total answer different questions. An event total shows how many separate releases an agency recorded. A distinct-water total shows the breadth of named locations in the indexed data. A reported-fish total adds the quantities supplied by the agency. None is a live census of fish in the water.
Comparisons also inherit the scope of the original reports. Agencies can have different start years, update schedules, fish-size labels, and date precision. StockedWaters normalizes the fields needed to compare records, but it does not turn a month-level report into an exact day or fill in quantities that the agency did not publish.
What a cumulative stocking total cannot tell you
- A large historical total does not prove that fish are present or catchable today.
- A named water in the data is not automatically public, open, or managed under standard statewide rules.
- A reported quantity does not predict survival, fishing pressure, or an angler’s likely catch rate.
- A newer source entry can supersede a prior plan or reveal a different date precision.
How should anglers use a rainbow trout stocking record?
Use the record as a planning clue, then verify it. Reporting systems differ: some agencies publish an exact day, while others publish a week, month, or year. StockedWaters preserves that source precision instead of converting a less-specific report into a made-up date.
- Step 1: Start with the water’s rainbow-trout page, not a statewide total.
- Step 2: Compare the latest reported date, fish size, and quantity only at the precision shown.
- Step 3: Open the reporting agency’s current page for any last-minute changes, closures, or regulation updates.
How to check the source before a trip
For the current source records, use the Utah DWR stocking report, Montana FWP stocking database, Washington fishing and stocking reports, and New York DEC fish-stocking data. They are the authorities when their live listings differ from an archived record.
Always check the water-specific rules and access conditions before fishing. A stocking report is evidence of a reported release, not a substitute for the current regulations.

Berkley PowerBait Floating Trout Dough
Hatchery-raised trout are conditioned to pelleted scents; scented dough floated 12–18 inches off bottom consistently triggers strikes.
Panther Martin Classic Teardrop Inline Spinner
The heavy convex blade spins instantly upon retrieval, sending vibration through the water that triggers aggressive reaction bites along drop-offs.
Sliding Sinker & Treble Hook Rigging Kit
Sliding egg sinkers allow cautious trout to run with bait without feeling line drag, while size 14–16 treble hooks keep dough bait securely pinned.

Frequently asked
Which states stock rainbow trout?
In the StockedWaters live datasets, Utah, Montana, Washington, and New York report rainbow trout stocking. A state-level total is only a starting point: anglers should open the specific water’s record and then confirm the agency’s current report and fishing rules before making a trip.
Are rainbow trout the most commonly stocked fish?
Within the four-state StockedWaters snapshot, rainbow trout have the most reported stocking events and the broadest water coverage: 201,069 records at 4,532 waters. That statement describes this dataset only, not every state or every freshwater fishery in the United States.
Does a rainbow trout stocking record mean fish are still there?
No. A stocking record documents a reported release, not a guarantee that fish remain, are catchable, or are legal to keep. Water temperature, fishing pressure, survival, access, and local rules all matter. Check the latest agency report and regulations for the water you plan to fish.
How can I find the most recent rainbow trout stocking?
Search by the named waterbody on StockedWaters, read the date at the precision displayed, and follow the linked state agency source for the current report. Utah, Montana, Washington, and New York publish their data differently, so do not assume every listed date has day-level precision.
