Idaho fishing rules depend on the water — not just the fish
Idaho’s statewide rulebook is only the starting point. Regional bag limits, special-water restrictions, salmon and steelhead permits, emergency closures, fish-species protections and river-specific rules can completely change what is legal.
Idaho does not use one statewide bag-limit table for every water
Most Idaho waters are open year-round unless a special rule says otherwise.
Regional general rules commonly set possession at three times the daily bag.
Catch-and-release in Idaho’s standard regional rules.
Cannot be removed from the water under standard rules.
Specific seasons and permits control ocean-run fish.
Five checks before you cast
Name the river reach, reservoir, creek or lake.
Regional bag limits are the default baseline.
Look for closure, length, gear or catch-and-release wording.
Separate live season pages and permit requirements apply.
Check recent Fish and Game closure or conservation orders.
Idaho fishing regulations are organized into seven regions
Read Idaho regulations in this order
Why an Idaho “general bag limit” still needs the region
Idaho Fish and Game intentionally publishes regional default limits. The examples below show why anglers should not memorize one statewide number.
| Species | Example rule | What this teaches |
|---|---|---|
| Trout — Clearwater rivers/streams | 2 combined | Clearwater stream limits can be lower than common lake limits. |
| Trout — Clearwater lakes/reservoirs | 6 combined | Water type can matter even within the same region. |
| Trout — Magic Valley general rule | 6 combined | Rivers/streams may also restrict how many cutthroat can be kept. |
| Brook trout | 25 in several regions | Brook trout are often listed separately from the combined trout limit. |
| Bull trout | CATCH & RELEASE | Do not treat bull trout as part of an ordinary harvestable trout bag. |
| Kokanee | Varies by region | Some regional defaults are 6, others can be substantially higher. |
| Whitefish | 25 in several regions | Special gear/bait rules on a named water can still override harvest methods. |
| Tiger muskie | 2; none under 40″ | Size limits can matter as much as bag limits. |
| White sturgeon | CATCH & RELEASE | Special handling and tackle requirements apply. |
One river can contain several different fishing regulations
Teton River
- No harvest of cutthroat trout.
- No limit on rainbow trout or trout hybrids.
- June 1–June 30 closure applies under the listed special rule.
Selway River
The lower section below the Selway Falls cable car uses seasonal trout rules, barbless hooks and no-bait periods.
A separate reach around Selway Falls is closed to fishing.
Why location pins matter
“I’m fishing the Selway” is not enough information. You need the exact reach because rules can change at a bridge, cable car, tributary or posted boundary.
Bull trout: catch, keep it wet, release it
Standard Idaho regional rules list bull trout as catch-and-release.
Do not confuse a bull trout with another trout or char before retaining fish.
Gear, bait or seasonal restrictions can still apply to the water.
Idaho Chinook seasons can close before the printed end date
South Fork Salmon River
The 2026 summer Chinook fishery closed at the end of fishing hours on July 29.
Upper Salmon River
Summer Chinook opportunities were managed under a separate 2026 season framework and are subject to closure orders.
Salmon River Basin spring Chinook
Idaho Fish and Game reported the spring Chinook fisheries in the Salmon River Basin closed for the season in June.
Fall Chinook / Coho
Fall Chinook and coho use separate season pages and should be checked by exact river section.
A fishing license alone is not enough when targeting Idaho salmon or steelhead
Ordinary fishing
A valid Idaho fishing license is required for anglers age 14 or older.
Targeting Chinook or coho
Add a salmon permit to the fishing license.
Targeting steelhead
Add a steelhead permit.
Resident permit price
$15.25Regular current resident salmon or steelhead permit price. Price Lock pricing can differ.
Idaho steelhead fishing spans much of the year — but harvest status changes by river
Idaho describes spring steelhead seasons as generally running January through May and fall seasons from July through December. Exact river sections can be open for harvest, catch-and-release only, or closed.
August 2026 examples
- Several upper Clearwater and South Fork Clearwater fall sections are listed as catch-and-release only beginning July 1.
- The Boise River 2026 steelhead listing is open year-round with a daily limit of 2 and possession limit of 6.
- Other Snake, Clearwater and Salmon River reaches can have different harvest limits and opening dates.
Idaho sturgeon fishing is catch-and-release — and even C&R can temporarily close
Statewide handling baseline
- White sturgeon are catch-and-release.
- They must not be removed from the water.
- Release the fish upon landing.
- Barbless hooks are required under the standard rule.
- Specific weight/leader rigging requirements apply.
C.J. Strike Reservoir — Snake River arm
Idaho Fish and Game issued a conservation closure for sturgeon fishing in the Snake River arm between Canyon Creek and Rattlesnake Creek.
The closure became effective August 2 and is scheduled through September 25 unless conditions allow an earlier change.
Want to fish two rods? Check both the permit and the water
Who needs it?
An angler who wants to fish with two poles must have the required two-pole permit where two-pole fishing is allowed.
Resident price
$15.00Regular current price; Price Lock amount can differ.
Water can still prohibit it
Buying the permit does not override a special-water rule restricting the number of fishing lines.
Idaho fishing-license requirement starts at age 14
Resident and nonresident youth rules differ in how fish are counted when fishing with licensed adults.
Current regular resident adult fishing-license price; Price Lock pricing can differ.
Idaho’s 2026 Free Fishing Day has already passed
On Idaho Free Fishing Day.
Size, bag, season and special-water restrictions are not waived.
If you see any of these phrases, do not rely on the general regional limit
Fishing may be allowed, but that species must be released.
Do not intentionally fish in the closed water or for the closed species.
Artificial lure/fly requirements can apply even if bait is legal elsewhere.
Modify tackle before fishing the special-rule reach.
Minimum length applies before the fish enters your possession.
Harvest is prohibited even if the general regional bag is larger.
Natural bait cannot be substituted.
Seasonal spawning-protection closures are common on special waters.

Ten regulation errors to avoid
Some regions and river types use lower limits.
Standard rules require catch-and-release.
Idaho’s standard sturgeon rule prohibits this.
South Fork Salmon closed before the broad August 10 framework in 2026.
Fishing license alone is not sufficient.
Separate permit required.
Bridges, tributaries and posted boundaries can change the rule.
Special Rules control even when bait is legal regionally.
The water itself must allow two-pole fishing.
Summer heat and low oxygen can trigger protective closures.
The useful rule is above — use these for the final live check
Practical answers before you fish
Are Idaho fishing seasons open year-round?
Most Idaho waters are generally open year-round unless a regional or named-water Special Rule establishes another season or closure. Salmon and steelhead use separate season frameworks.
What is Idaho’s statewide trout limit?
Idaho does not use one single trout harvest limit for every water. Regional general bag limits differ, and named-water Special Rules can further reduce harvest, impose catch-and-release or close fishing.
Can I keep bull trout in Idaho?
Standard Idaho fishing rules list bull trout as catch-and-release. Special-water tackle or seasonal restrictions can also apply.
Can I keep white sturgeon in Idaho?
No. Idaho’s standard white sturgeon fishery is catch-and-release. Sturgeon must not be removed from the water and specified tackle requirements apply.
Is any Idaho sturgeon fishing temporarily closed in August 2026?
Yes. Idaho Fish and Game issued a temporary conservation closure for sturgeon fishing on the Snake River arm of C.J. Strike Reservoir between Canyon Creek and Rattlesnake Creek, effective August 2 through September 25 unless changed earlier.
Do I need a permit to fish for salmon in Idaho?
Yes. In addition to a valid fishing license, anglers targeting Chinook or coho salmon need the applicable salmon permit.
Do I need a permit to fish for steelhead in Idaho?
Yes. A steelhead permit is required in addition to a valid Idaho fishing license when fishing for steelhead.
Is the South Fork Salmon River still open for Chinook in August 2026?
No. Idaho Fish and Game closed the 2026 summer Chinook fishery on the South Fork Salmon River at the end of fishing hours on July 29, 2026.
What age requires an Idaho fishing license?
A valid Idaho fishing license is generally required for anyone age 14 or older. Anglers younger than 14 do not need an ordinary fishing license, although resident and nonresident youth harvest provisions differ.
Does an Idaho two-pole permit allow two rods everywhere?
No. A two-pole permit allows two-pole fishing only where the water itself permits it. A special-water rule can still restrict fishing to one line or otherwise limit gear.
Region first. Special water second. Current closure last.
Idaho fishing rules make much more sense when you stop searching for one statewide number. Identify the exact water, apply its regional default, read the Special Rule and then check live salmon, steelhead or conservation-closure notices before keeping fish.
