Fish Yosemite legally: one park, very different trout rules
Yosemite fishing changed in 2026. Park waters are now generally open year-round, but Yosemite adds its own federal rules on top of California law: artificial lures only park-wide, special barbless-hook waters, zero-harvest rainbow trout in major river systems, and strict Hetch Hetchy protections.
What you need before fishing Yosemite in 2026
Most anglers 16 or older need a valid California sport fishing license.
Current Yosemite rules open park waters all year, subject to specific restrictions.
Yosemite permits artificial lures only for fish species park-wide.
Five daily and ten in possession unless a special-water rule overrides it.
Merced, South Fork Merced, Tuolumne and inland tributaries.
Zero bag in Yosemite’s listed special river systems.
Do not use Yosemite’s old April-to-November stream-season advice
Some older park pages still contain historical seasonal wording. The current May 2026 Superintendent’s Compendium and updated NPS fishing page use year-round fishing with specific water protections.
Seasonal stream window
Older Yosemite material described stream and river fishing from late April through November 15.
Park waters open year-round
Yosemite’s current Compendium states that all park waters are open to fishing year-round, with the special restrictions explained below.
Choose where you plan to fish
Educational summary only. Current NPS/CDFW rules and posted closures control.
Artificial lure or fly only. Use barbless hooks. Rainbow trout: catch-and-release, zero bag. Brown and brook trout: 5 daily / 10 possession.
Yosemite rules that follow you from one drainage to another
Artificial lures only
Current NPS Compendium states that only artificial lures may be used for all species of fish in Yosemite.
Lead-weight limit
Lead weights used on fishing lines may not exceed 0.25 ounce per line.
No bridge fishing
Fishing from vehicle, pedestrian or stock bridges and park piers is prohibited.
No live-fish transport
Transporting live fish any distance within Yosemite is prohibited.
Six practical Yosemite fishing plans
Merced River — Yosemite Valley
The easiest river-focused plan for many visitors. Current NPS rules make rainbow trout catch-and-release only. Brown and brook trout are five daily and ten in possession.
Practical move:Fish legal shoreline rather than bridges. During stronger current, work protected edges, seams and slower water rather than standing deep.
South Fork Merced — Wawona
Same special trout framework: artificial lures, barbless hooks, zero harvest of rainbow trout, and the listed brown/brook limit.
Practical move:Treat this as moving-water fishing, not a stocked-lake bait trip. Use a compact one-rod artificial setup.
Tuolumne River / Tuolumne Meadows
NPS identifies the Tuolumne system and its inland tributaries under the special barbless rule. Brown, rainbow and brook trout are among fish documented in the Tuolumne system.
Practical move:Check Tioga Road before leaving. High-country access is seasonal even though the fishing regulation itself is now year-round.
Hetch Hetchy Reservoir
Fishing from the top of O’Shaughnessy Dam is prohibited. While fishing the reservoir, wading, swimming and other bodily contact with the water are prohibited except using hands to retrieve or release fish.
Practical move:Fish from legal shoreline, wear footwear suitable for rocky banks, and remember Hetch Hetchy Road operates sunrise to sunset for day users.
Adair & Hanging Basket Lakes
Only artificial lures with barbless hooks may be used and all trout have a zero daily bag and zero possession limit.
Practical move:Carry release-focused gear and do not build the trip around keeping dinner.
Tenaya & other park lakes
Where no tighter named-water rule applies, the park-wide trout baseline is five daily and ten in possession, with artificial lures only.
Practical move:Search the exact lake name in current rules before keeping fish. Not every high-elevation lake contains trout.
What California fishing license do you need for Yosemite?
Visitors age 16 or older generally need a valid California sport fishing license before attempting to take fish in Yosemite. The license is issued by the California Department of Fish and Wildlife, not by the National Park Service.
2026 CDFW fees. Official checkout controls the final transaction. California 365-day licenses are valid for 365 days from purchase.
Which option makes sense?
- One Yosemite fishing day: compare the $21.09 one-day license.
- Weekend: the $32.40 two-day option covers two consecutive days.
- Long visiting trip: nonresidents can compare the 10-day license.
- California resident fishing repeatedly: 365-day license is the main annual route.
- Under 16: base sport fishing license is generally not required, but park rules still apply.

Buy the license before entering weak-service areas
- Open CDFW’s official Online License Sales and Services portal.
- Sign in to your customer record or create the required GO ID/customer profile.
- Select the sport fishing license that matches your residency and trip length.
- Verify the start date carefully—especially with one-day and two-day products.
- Review the cart before payment because CDFW license sales are generally final.
- Save the issued license/receipt and make sure valid proof is in your immediate possession while fishing.
CaliforniaFishingLicense.website is an independent educational guide. It does not issue licenses and is not CDFW, CA.gov or the National Park Service.
Check Yosemite fishing rules before you cast
- Name the exact water. Merced, South Fork Merced, Tuolumne, Hetch Hetchy, Tenaya or a specific backcountry lake.
- Open the current Yosemite fishing page and Superintendent’s Compendium. Park rules can be more restrictive than California’s general rule.
- Confirm lure and hook restrictions. Yosemite is artificial-lure-only; listed river systems and special lakes require barbless hooks.
- Identify the trout species before keeping it. Rainbow trout have zero harvest in Yosemite’s designated river systems.
- Check current access. Tioga Road, Hetch Hetchy Road, snow, fire, construction and temporary closures can change the practical trip.
- Carry proof and save the current rule offline. High-country cell service should not be part of your compliance plan.

Yosemite trout tactics that fit the park’s actual rules
Yosemite’s lure rule changes the normal Sierra trout playbook. Leave bait rigs at home and build around unscented artificial flies and lures.
Small barbless nymphs or wet flies
On the special river systems, use barbless patterns and work current seams, pocket water and softer edges instead of repeatedly casting the deepest run.
Match the surface activity
If trout are visibly rising, switch from searching water to a small dry-fly presentation and reduce unnecessary false casting over fish.
Search with small unscented hardware
Where legal under the exact water’s rule, compact spoons or spinners can cover shoreline efficiently. Avoid scented coatings or attractants.
Back away from the edge
Sierra water can be very clear. Approach quietly, keep your silhouette off shallow water and cast before walking to the bank.
Protect fish, not the photo
For mandatory-release rainbow trout, minimize handling and keep the fish in the water as the NPS specifically directs.
Do not hike miles on a stocking assumption
Some Yosemite lakes are naturally or intentionally fishless. Research the water before building the entire trip around trout.
Trout identification matters because harvest rules are species-specific
Native at Yosemite’s lower elevations; introduced in many higher areas. Zero harvest in the designated Merced/South Fork/Tuolumne river systems.
Non-native and established in Yosemite waters. Five daily / ten possession in the listed special river systems.
Non-native trout present in the park. Same listed five / ten special-river limit as brown trout.
NPS lists golden trout and Kokanee salmon among sport fish found in Yosemite waters, but presence varies by waterbody.
Fishing may be year-round; road access is not
Tioga Road
NPS current conditions lists Tioga Road open. It normally closes seasonally with snow, so recheck before any Tuolumne Meadows or Tenaya plan.
Hetch Hetchy Road
Open sunrise to sunset for day use and subject to weather-related closure.
2026 park entry
Yosemite does not require a vehicle entrance reservation in 2026. The entrance fee still applies.
Park entrance
NPS lists the standard private-vehicle entrance pass at $35, valid for seven consecutive days.
Hetch Hetchy is the easiest place to make a water-contact mistake
Fishing from the top of O’Shaughnessy Dam is prohibited.
Bodily contact with reservoir water is prohibited while fishing.
NPS provides a narrow hands-only exception to retrieve or release fish.
Parking is limited; plan the exit before daylight access ends.
Yosemite wants anglers to stop aquatic hitchhikers at the boot sole
NPS specifically warns that fishing clothing, footwear, nets and watercraft can move invasive organisms such as Didymo between rivers and lakes.
Your trout cooler is bear-attractant storage
Yosemite’s food-storage rules treat scented items broadly. Fish, bait-like materials, food, trash and coolers should never be left accessible to wildlife.
Day use
Keep food and scented items within arm’s reach of an awake person or store them in an approved location/container.
Campground
Use the provided food locker and keep it latched whenever food/scented items are not actively being used.
Wilderness overnight
Approved bear-resistant food containers are required. Hanging food is not the Yosemite backcountry storage method.
Legal harvest and recommended consumption are different questions
NPS directs anglers to California’s statewide fish-consumption advice for lakes and reservoirs because mercury, including methylmercury in fish tissue, can affect meal recommendations.
Yosemite fishing area map
Use the map for orientation, then use the NPS park map and current road-status page before driving to Hetch Hetchy or the high country.
If Yosemite access or fishing style does not fit your plan
Want stocked-lake style trout fishing?
Yosemite is artificial-lure-only and many waters emphasize resource protection rather than hatchery-style harvest. For a very different Eastern Sierra trip, compare our Mammoth Lakes trout planner , which covers drive-to lakes, seasonal CDFW rules and boat-inspection issues.
Want several drive-to lakes in one loop?
East of Yosemite, the June Lake Loop fishing guide compares June, Gull, Silver and Grant Lakes plus Rush Creek’s regulation traps.

Questions anglers ask before fishing Yosemite
Do I need a California fishing license in Yosemite?
Most anglers age 16 or older need a valid California sport fishing license before fishing Yosemite National Park. Yosemite does not issue a separate recreational park fishing license.
Is Yosemite fishing open year-round in 2026?
Yes. The current May 2026 Yosemite Superintendent’s Compendium states that all waters within Yosemite National Park are open to fishing year-round, with specific waters subject to additional restrictions.
Can I use PowerBait, worms or scented bait in Yosemite?
No. Yosemite’s current park rule allows artificial lures only and separately prohibits live, dead and scented bait, including products that attract fish through taste or smell.
Do I need barbless hooks everywhere in Yosemite?
Artificial lures are required park-wide, but the current Compendium specifically requires barbless hooks on the Merced River, South Fork Merced River, Tuolumne River and their inland tributaries, as well as Adair and Hanging Basket Lakes.
Can I keep rainbow trout from the Merced River?
No. The Yosemite special river rule gives rainbow trout a zero bag limit in the Merced, South Fork Merced, Tuolumne and covered inland tributary system. Rainbow trout must be released unharmed and should not be removed from the water.
What is the brown and brook trout limit in Yosemite’s special rivers?
The current Yosemite rule lists five brown or brook trout per day and ten in possession in the Merced River, South Fork Merced River, Tuolumne River and inland tributaries covered by the special rule.
Can I wade while fishing Hetch Hetchy Reservoir?
No. Yosemite prohibits wading, swimming and other bodily contact with Hetch Hetchy Reservoir while fishing, other than using your hands to retrieve or release fish. Fishing from the top of O’Shaughnessy Dam is also prohibited.
Can I use two fishing rods in Yosemite with a Second Rod Validation?
Do not plan on it. CDFW states that Second Rod Validation does not apply on inland waters where only artificial lures or barbless hooks may be used, and Yosemite currently requires artificial lures park-wide.
Is Tioga Road always open for Tuolumne fishing?
No. Tioga Road is seasonal even though Yosemite fishing is now year-round. It was listed open during this September 18, 2026 review, but snow and other conditions can close the high-country route.
Do I need a Yosemite entrance reservation in 2026?
No vehicle entrance reservation is required for Yosemite in 2026, but the park entrance fee still applies. Camping, lodging and overnight wilderness travel have their own reservation or permit requirements.
