Utah Ice Fishing: Strawberry Reservoir Cutthroat & Fish Lake Splake Guide

Utah ice fishing is genuinely underrated. Strawberry Reservoir holds Bonneville cutthroat trout that regularly push past 20 inches, Fish Lake produces splake that most western anglers don't know exist, and a dozen high-elevation reservoirs fill out a season running December through March. If you're driving from Las Vegas, Phoenix, or southern California to chase trout under ice, Utah deserves a serious look — and the state's elevation profile makes safety gear decisions more consequential than at lower-altitude fisheries.

This guide covers the two best destinations in depth, explains the regulation details that catch out-of-state visitors, and addresses the float suit question that comes up every time someone plans a Utah ice fishing trip at 7,000 feet or higher.

Key Takeaways

• Strawberry Reservoir is Utah's premier ice fishery, targeting Bonneville cutthroat trout and rainbow trout; the season typically opens when ice reaches safe thickness in late December or January
• Fish Lake sits at 8,848 feet elevation and produces splake (brook-lake hybrid) up to 8 pounds in a short but productive window, usually January through mid-March
• Utah requires a fishing license for all anglers 12 and older; no separate ice fishing license is needed, but daily bag and possession limits for cutthroat at Strawberry differ from statewide rules
• Elevation above 7,000 feet creates unpredictable ice thickness variations and cold-water immersion risks that make a float suit a practical safety tool, not optional equipment
• The Utah Division of Wildlife Resources (DWR) publishes weekly ice reports for Strawberry Reservoir during the season — check these before every trip

Strawberry Reservoir Ice Fishing

Strawberry Reservoir sits at 7,600 feet elevation in Wasatch County, about 75 miles southeast of Salt Lake City. The reservoir covers roughly 17,000 surface acres when full, making it the largest recreational reservoir in Utah and one of the most productive trout fisheries in the Intermountain West.

What You're Fishing For

Bonneville cutthroat trout are the signature catch. Strawberry holds a reproducing population of Bonneville cutthroat — a subspecies native to the Bonneville Basin — along with stocked rainbow trout and a smaller splake population. Under the ice, cutthroat average 14 to 18 inches, with fish over 20 inches caught regularly near the Soldier Creek arm and along the main basin's deeper flats.

Rainbow trout are aggressive biters in late winter, particularly in February when they stage near inlet areas. Splake at Strawberry are a bonus fish — they appear in catch reports but aren't the primary target here the way they are at Fish Lake.

Ice Conditions and Season Timing

Because Strawberry sits above 7,500 feet, it typically freezes earlier and harder than lower-elevation Utah lakes. Safe ice (4 inches minimum for foot travel, 8-12 inches for snowmobiles) usually forms between late December and mid-January depending on air temperatures. The season runs through late February to mid-March before ice begins to soften.

The Utah DWR posts ice condition updates on its website and through regional offices during the winter. These reports are not bureaucratic formality — Strawberry's shallow bays can produce 14 inches of solid ice while the main basin runs thinner due to wind currents and depth variation. Check the report before you drive two hours from Salt Lake.

Strawberry Reservoir Regulations (Current as of 2025-2026 Season)

Out-of-state anglers frequently get caught by Strawberry's special regulations. The key points:

• Cutthroat trout limit: 2 cutthroat per day, with a 15-inch minimum size limit. This is more restrictive than the statewide cutthroat limit.
• Rainbow trout: Standard statewide limit applies (check current DWR regulations for exact number, as limits are reviewed annually).
• License requirement: Utah fishing license required for all anglers 12 and older. Annual, 7-day, and 1-day licenses are available through the Utah DWR online portal or at license agents in Heber City and surrounding towns.
• Tackle restrictions: Check for any bait restrictions on Strawberry — the reservoir has had periodic bait fish regulations to protect native cutthroat.

Always verify current season regulations at the Utah DWR website before your trip. Regulations for Strawberry are reviewed annually and have changed in recent seasons.

Where to Drill at Strawberry

The Soldier Creek area on the south end of the reservoir consistently produces the most cutthroat reports. The flats between 20 and 35 feet of water hold fish through most of the ice season. The Strawberry Bay marina area sees heavy pressure early in the season when ice first forms there.

Mid-lake humps and submerged structure hold fish but require a GPS unit and prior knowledge — these spots aren't obvious on the ice. Jigging small spoons (1/4 to 1/2 oz) in silver or gold, or using PowerBait under a bobber in 25-30 feet, are the two most productive methods.

Fish Lake Ice Fishing

Fish Lake is a different experience from Strawberry: smaller (2,600 acres), higher (8,848 feet), and more remote. It sits in Sevier County in south-central Utah, roughly 20 miles west of Capitol Reef National Park, and is accessible via Highway 25.

Splake: The Species Worth the Drive

Fish Lake is one of the few western fisheries where splake are actively managed as a primary target species. Splake (a brook trout-lake trout hybrid) were introduced in the 1980s and have become the dominant sport fish. They grow faster than either parent species — fish pushing 24 to 28 inches and 6 to 8 pounds are caught every season.

Splake are aggressive and respond well to jigging. They favor depths between 40 and 70 feet in winter, suspending over the deepest parts of the lake's basin. Large tube jigs, swim baits, and spoons in the 1/2 to 1 oz range outperform finesse presentations. Tip your jig with a sucker meat chunk if you want to add scent.

The lake also holds tiger trout and rainbow trout, though splake dominate the winter catch.

Fish Lake Regulations

Fish Lake operates under special regulations separate from the statewide trout limits:

• Trout limit: 4 fish per day total (all species combined), with specific size restrictions that change periodically — verify with DWR before your trip
• Season: Fish Lake is open year-round for ice fishing when conditions allow
• Access: The Fish Lake Lodge area provides the most accessible ice access; the south end of the lake near the boat ramp is another common entry point

At nearly 9,000 feet, Fish Lake receives substantial snow accumulation. Four-wheel drive is advisable from late December through March. The road from Highway 24 is typically plowed, but the lodge and campground areas may require snow travel.

Ice Thickness at Fish Lake

Fish Lake's depth (average 35 feet, maximum around 110 feet) and protected basin mean it typically forms strong ice — but its elevation creates one critical hazard. Snowfall insulates ice from further freezing while adding weight. This can produce thick-looking ice that's structurally weaker than the drill hole suggests. The standard practice among Fish Lake regulars is to drill a test hole every 50 yards when moving to new ice.

This is exactly the situation where the float suit safety guidance matters most: deep, cold water at altitude with variable ice that you can't assess visually.

The Utah Elevation Factor and Float Suit Safety

Most of Utah's productive ice fisheries sit above 7,000 feet. That elevation creates a compounding physiological problem when someone falls through. Cold shock — the involuntary gasp and hyperventilation response — happens within the first 30 seconds in near-freezing water regardless of fitness level. At altitude, reduced ambient oxygen makes this response harder to manage than at sea level.

Time-to-incapacitation in near-freezing water runs 3 to 10 minutes depending on body mass. A float suit keeps your head above water during that window, buying time for self-rescue or bystander assistance. It doesn't prevent the fall — it extends the margin.

Three Utah-specific factors make float suits more relevant here than at typical Midwest fisheries:

1. Elevation-driven physiological stress — cold shock is harder to manage at altitude
2. Remote access — Fish Lake and backcountry reservoirs have long emergency response times
3. Variable ice quality — heavy snowfall insulates ice from freezing while adding load, creating structurally weaker ice that appears solid

The Boreas Ice Fishing Float Suit addresses this directly: integrated flotation without a separate PFD, rated to -40°F for high-altitude cold. The Boreas Pro Floating Ice Fishing Bibs are a strong alternative for anglers who prefer layering their own jacket. If you want to evaluate float suit designs before committing, the ice fishing float suit comparison guide explains how integrated flotation ratings work and what the specs actually mean.

Other Utah Ice Fishing Locations Worth Knowing

Strawberry and Fish Lake get the most attention, but Utah has more options worth considering:

Scofield Reservoir (7,618 ft, Carbon County): Cutthroat and tiger trout with less pressure than Strawberry. About 2,800 acres managed as a quality trout fishery; access from the state park area.

Flaming Gorge Reservoir (6,040 ft, Daggett County): Lower elevation means inconsistent freeze years, but when ice forms in January, the lake trout bite above the dam is exceptional. Note that Flaming Gorge has specific lake trout regulations separate from the statewide limit.

Panguitch Lake (8,400 ft, Garfield County): Consistently productive rainbow trout fishery in southern Utah, roughly 4 hours from Las Vegas — the closest quality ice destination for Southwest anglers.

Causey Reservoir (5,700 ft, Weber County): Lower elevation means shorter ice seasons but reliable road access. Cutthroat and tiger trout; popular with Ogden-area anglers as a day trip.

Utah Ice Fishing Gear: What You Actually Need

Utah ice fishing doesn't require specialized gear beyond any cold-weather fishery — with one notable exception: sun exposure. At 7,500+ feet, UV intensity is measurably higher than at sea level (roughly 4% per 1,000 feet of elevation gain), and snow reflection amplifies it from below. On a clear February day at Strawberry, you're absorbing far more UV than the calendar date implies. Wind and cold mask sunburn until it's done. A balaclava and SPF lip balm are not optional at these elevations.

Essential gear checklist for Utah ice fishing:

• Ice auger (8-inch minimum for Strawberry cutthroat, though 6-inch works)
• Sonar/fish finder (especially important for Fish Lake's deeper water column)
• Ice fishing rod with light to medium-light sensitivity for jigging
• Tip-ups if regulations allow (check Strawberry's tip-up rules)
• Float suit or PFD — non-negotiable at high-altitude remote fisheries
• Traction cleats for boot ice grip
• Ice picks (worn around neck) for self-rescue
• Insulated sled for gear transport
• Sunscreen and face protection

For anglers who want to review the complete safety picture, the ice fishing safety gear guide covers self-rescue tools, ice thickness standards, and the layering decisions that affect both warmth and mobility under a float suit.

FAQ

Do I need a separate ice fishing license in Utah, or does a standard fishing license cover ice fishing?
A standard Utah fishing license covers all fishing methods including ice fishing — no separate permit is required. However, Strawberry Reservoir and several other waters have special regulations (size limits, bag limits, tackle restrictions) that differ from statewide defaults. Verify the rules for each specific water through the Utah DWR website or regulation booklet before your trip.

What is the minimum ice thickness for safe fishing at Strawberry Reservoir?
The standard benchmark is 4 inches of clear solid ice for a single angler on foot, 5-7 inches for a group, and 8-12 inches for snowmobiles. At Strawberry, thickness varies significantly between shallow bays and the main basin due to wind currents — don't rely on visual assessment alone. Drill test holes as you move and check the DWR's published ice condition updates before leaving home.

Are there any restrictions on fishing shelters or ice shanties at Utah ice fisheries?
Utah doesn't require permits for portable shelters, but most waters — including Strawberry — prohibit leaving shanties overnight without specific authorization. Before running a propane heater inside an enclosed shelter, check current fire restrictions; higher-elevation fisheries sometimes fall under forest or state park fire rules that apply year-round.

Can I keep lake trout at Flaming Gorge if I catch them through the ice?
Yes, but Flaming Gorge has its own lake trout regulations including size limits and slot limits that have changed multiple times in recent years. The statewide trout limit does not apply there. Always pull the current Flaming Gorge-specific regulations from the DWR website before your trip.

What's the best approach for transporting fish on the drive home from a high-elevation Utah fishery?
Ambient temperatures at 7,000+ feet in winter keep fish frozen during the fishing day without a cooler. The problem is the return drive — particularly for anglers heading to Las Vegas or Phoenix. Pack a dedicated insulated cooler with commercial ice for the drive home. Fish frozen at the point of catch and kept continuously cold arrive in good condition even after a 4-5 hour drive.
