The Flaming Gorge Fishing Derby runs each June on the Utah side of the reservoir
The Flaming Gorge Fishing Derby is an annual event held in mid-June on Flaming Gorge Reservoir, with weigh-in stations and prize categories for anglers of all ages. The derby typically runs for one weekend — check with the Utah Division of Wildlife Resources closer to the event for exact dates, as they can shift by a week or two depending on the year. Entry is open to anyone with a valid Utah fishing license, and you fish from your own boat or from shore during the designated hours.
The event draws families, serious anglers, and people new to fishing because the structure is straightforward: you catch fish during the derby window, bring them to the official weigh-in before the deadline, and compete in categories like largest walleye, largest trout, or youth division. Prizes are awarded in each category, and the atmosphere is built around community rather than exclusion — you do not need to pre-register or pay an entry fee beyond your fishing license.
Key Takeaways
- The Flaming Gorge Fishing Derby takes place each June on the Utah portion of the reservoir, with exact dates announced by the Utah Division of Wildlife Resources.
- You need a valid Utah fishing license to enter, but there is no separate entry fee or pre-registration requirement for the derby itself.
- Fish are weighed at official stations during set hours on the final day of the derby, and you must bring your catch there before the deadline to compete.
- Prize categories include largest fish by species and youth divisions, so families with children and first-time anglers have their own competitive brackets.
- The reservoir holds walleye, lake trout, and smallmouth bass, so your target species depends on what you want to fish for and what the current bite favors.
Where to fish and what species to target
Flaming Gorge Reservoir spans the Utah-Wyoming border, but the derby is held on the Utah side. The reservoir is known for walleye, lake trout (also called mackinaw), and smallmouth bass. Walleye tend to bite best in early morning and evening, especially in deeper water or near structure like rock ledges. Lake trout can be caught throughout the day but often hold in deeper zones — 40 to 80 feet — so you will need a depth finder or local knowledge to locate them efficiently.
Smallmouth bass are shallower and more active around rocky points, drop-offs, and weed beds. June is early summer, so the water is warming but not yet hot; fish are still in their spring feeding patterns and relatively active. If you are new to the reservoir, talk to the marina staff or local tackle shops before the derby — they know which areas are producing that week and can point you toward the most likely spots.
How to enter and what to bring
Entry requires only a valid Utah fishing license, which you can purchase online through the Utah Division of Wildlife Resources website or at any authorized vendor. There is no separate derby entry fee, and you do not need to register in advance. You fish during the announced derby hours — typically from dawn on the first day through late afternoon on the final day — using your own boat or fishing from shore at accessible points around the reservoir.
Bring your fishing gear, a cooler with ice to keep fish fresh, and your license. You will also need to know the weigh-in location and the exact deadline time, which the Utah Division of Wildlife Resources publishes when they announce the derby dates. Arrive at the weigh-in station before the deadline with your fish in good condition — they will be weighed, measured if applicable, and recorded. Keep your receipt or documentation in case of a tie.
Prize categories and what you can win
The derby awards prizes for the largest fish in each species category — typically largest walleye, largest lake trout, and largest smallmouth bass. There is usually a youth division (often for anglers under 16) with its own prizes, so children fishing with a license can compete separately from adults. Some years the event also includes a family category or a most fish caught category, though the main focus is on size.
Prizes vary by year but often include fishing gear, tackle, or gift certificates to local businesses. The exact prize structure is announced when the derby dates are released. The real draw for many people is the chance to compete in a structured event, see what others are catching, and be part of a fishing community gathering — the prizes are a bonus rather than the main reason to show up.
Fishing regulations and what you need to know
Utah fishing regulations apply during the derby, so you must follow all state rules for license type, catch limits, and size restrictions. A standard Utah fishing license covers most anglers, but if you do not live in Utah, you will need a non-resident license. Check the current regulations for Flaming Gorge before you fish — daily catch limits and minimum size requirements can change, and the Utah Division of Wildlife Resources website has the most current rules.
Fish must be alive or in good condition when you bring them to the weigh-in, so handle them carefully and keep them cool. Some anglers use a live well in their boat; others use a cooler with ice water. Do not keep fish longer than necessary, and if you plan to keep your catch for eating after the derby, follow proper handling and storage practices to maintain quality.
Getting to Flaming Gorge and where to stay
Flaming Gorge Reservoir is in northeastern Utah, about 40 miles north of Vernal. The main access points on the Utah side are at Lucerne Valley Marina and Red Canyon Lodge. Both have boat ramps, fuel, and supplies. If you are driving from Salt Lake City, the trip is roughly three to four hours; from Vernal, it is about an hour. The area has limited lodging, so book accommodations early if the derby falls on a weekend — options include small motels in Vernal or camping at nearby Forest Service sites.
The reservoir sits in high desert terrain with elevation around 6,000 feet, so weather can be variable in June. Bring sun protection, layers, and water. The drive is scenic but remote, so fill your gas tank before you leave town and bring any supplies you might need — the nearest grocery stores are in Vernal.
Preparing your fish for the weigh-in
Keep fish alive or on ice immediately after catching them. If you are using a live well, change the water regularly and keep the temperature as cool as possible. If you are using a cooler, pack it with ice before you leave home, add ice as needed throughout the day, and keep fish in the coldest part of the cooler. Do not stack fish on top of each other — they bruise easily, and bruised flesh affects both the appearance and the eating quality.
When you arrive at the weigh-in, have your fish ready to present. The official will weigh it, record the weight and species, and note the time. Keep your receipt. If you are planning to eat the fish after the derby, ask the weigh-in staff whether they have any guidance on handling — some events allow you to take the fish home after weighing, while others may have different procedures.
Frequently Asked Questions
Do I need to pre-register for the Flaming Gorge Fishing Derby?
No. You do not need to register in advance. You only need a valid Utah fishing license. Show up during the derby hours, fish, and bring your catch to the weigh-in station before the deadline.
Can I fish from shore, or do I need a boat?
You can fish from shore at accessible points around the reservoir. A boat gives you more water to cover and access to deeper areas where lake trout hold, but shore fishing is allowed and many people participate that way.
What if I catch a fish but it is damaged or dies before the weigh-in?
Bring it anyway. The weigh-in staff will weigh it as-is. Damaged fish can still win if they are the largest in their category, though keeping fish in good condition gives you the best chance of a clean weigh-in.
When do I find out the exact dates for this year's derby?
The Utah Division of Wildlife Resources announces the derby dates on their website, usually a few weeks before the event. Check their calendar or call the regional office in Vernal to confirm dates and weigh-in times.
Can children fish in the derby?
Yes. Children need their own fishing license (Utah offers youth licenses at a reduced rate), and most years there is a youth division with separate prizes. Check the derby announcement for age cutoffs and youth category details.
