What Mirror Lake offers and when to fish it
Mirror Lake sits at 10,000 feet in the Uinta Mountains, about 30 miles northeast of Kamas on Mirror Lake Highway. The lake holds native cutthroat trout and brook trout, with cutthroats dominating the catch. Most fish run 8 to 12 inches, though 14-inchers are not uncommon. The water is cold and clear, and the setting is high-altitude meadow and conifer forest — the kind of place where you can see weather coming from miles away.
The lake is open year-round on paper, but snow closes the highway from November through May most years. The real season runs June through October. July and August bring the most stable weather and the most people. June can be excellent if the road opens early, because the fish are still aggressive after spawning. September and early October offer fewer crowds and reliable fishing, though afternoon thunderstorms are common and water temperature drops fast.
Cutthroats here respond to small spinners, flies, and live insects. The lake has natural reproduction, so the fishery is self-sustaining. You will not find trophy fish, but you will find steady action in a setting that feels remote even though the trailhead is a short walk from the parking area.
Key Takeaways
- Mirror Lake Highway opens when snow melts, usually late May or early June, and closes again in November; call the Kamas Ranger District to confirm before driving.
- The lake holds cutthroat and brook trout in the 8- to 14-inch range, with best fishing in June and September when crowds are lighter.
- Afternoon thunderstorms are routine in summer and early fall; plan to fish morning and early afternoon, and watch the sky.
- The parking area has a developed campground and day-use facilities; arrive early on weekends, especially in July and August.
Getting there and what to bring
From Kamas, take Highway 150 (Mirror Lake Highway) northeast. The road climbs steadily and passes several smaller lakes and trailheads before reaching Mirror Lake, about 30 miles from town. The drive takes roughly 45 minutes in summer. The highway is paved but narrow and winding; do not attempt it in snow or when the road is wet and visibility is poor.
The parking area sits right at the lake. There is a developed campground with sites, vault toilets, and water. Day-use parking is free. Arrive by mid-morning on weekends if you want a spot close to the water. The lake is shallow near shore and drops off quickly — bring waders if you plan to wade, or fish from the bank and the small dock area.
Pack layers. The elevation means temperature swings are sharp. Morning can be in the 40s even in July; afternoons warm to the 60s or low 70s. Bring rain gear and a headlamp. Afternoon storms can move in fast, and if you are still on the water when lightning starts, you need to get off it immediately. The nearest services are in Kamas, so bring food and water for the day.
Tackle and technique for cutthroats
Cutthroats at Mirror Lake are not selective, but they are not aggressive either. Small spinners in silver or gold work well — size 0 or 1 Panther Martins or Mepps are standard. Cast from shore or from a boat if you bring one; the lake allows small motorboats and canoes. Retrieve slowly and pause occasionally. The fish will often hit on the pause.
Fly fishing is productive, especially early and late in the day. Small nymphs — size 14 to 18 — work better than dry flies most of the time. Pheasant Tail and Hare's Ear patterns are reliable. If you see rises, switch to a small dry fly, but expect the cutthroats to ignore it half the time and take it the other half. The water is clear, so use a long leader and light tippet.
Live bait — small minnows or insects — works but is less common here than on lower-elevation reservoirs. If you go that route, keep bait in a cooler and check regulations; some areas of the Uinta National Forest have restrictions on live bait. The Utah Division of Wildlife Resources website lists current rules by water.
Regulations and what you need to know
You need a valid Utah fishing license. The lake is in the Uinta National Forest, managed by the U.S. Forest Service. There is no special permit for Mirror Lake itself, but the forest has general rules: pack out what you pack in, camp only in designated areas, and keep fires in established rings or use a camp stove.
Cutthroat trout have a daily limit of 8 fish. Brook trout have the same limit. Check the Utah Division of Wildlife Resources website or the current fishing guidebook before you go, because regulations can change. The lake is in a general fishing area with no special restrictions, but that can shift if the fishery needs management.
The road is closed to vehicles in winter. If you want to fish in winter, you can hike in, but the distance and snow depth make it a backcountry trip, not a casual outing. Most anglers do not attempt it.
When to avoid Mirror Lake and where to go instead
If the highway is closed, do not try to drive it. Conditions can change fast, and a closed road means a long walk out if you get stuck. Call the Kamas Ranger District at (435) 783-4338 to confirm the road is open before you drive.
If you want to avoid crowds, skip July and August. June and September are better. If you want to fish in winter, the Strawberry Reservoir near Heber City stays open and accessible year-round, though it is lower elevation and the fishing is different — larger fish, but slower action.
If you want easier access and do not mind lower elevation, Causey Reservoir near Ogden is 45 minutes from Kamas and open most of the year. It holds walleye and catfish as well as trout, and the road is paved and plowed in winter. The trade-off is that it is busier and the setting is less remote.
Camping and staying overnight
The Mirror Lake Campground has about 80 sites, most with no hookups. Sites are first-come, first-served in summer. Reservations open in spring through Recreation.gov if you want to book ahead. Cost is around $20 to $25 per night, but check the current rate. The campground has vault toilets and water spigots but no showers or dump stations.
If the campground is full, there are smaller campgrounds on the highway between Kamas and Mirror Lake — Beaver View, Shady Dell, and others. These fill up later than Mirror Lake and are quieter. They are also closer to Kamas if you want to resupply.
Dispersed camping is allowed on Forest Service land outside the developed campground, but sites must be at least 100 feet from water and 50 feet from trails. Leave no trace and pack out all trash. The forest is dry in late summer, so check fire restrictions before you build a fire.
What the fishing pressure looks like
Mirror Lake is popular, especially on weekends and holidays. The parking area can fill by 10 a.m. on a Saturday in July. The lake itself is large enough that you can find quiet water if you walk, but the bank near the campground and parking area gets crowded. If you want solitude, hike to the upper end of the lake or fish early morning before most people arrive.
The fish are not pressured into being difficult — they still bite — but you will be sharing the water with other anglers. If you are looking for a remote experience, this is not it. If you want reliable fishing close to Kamas with a developed campground and a scenic setting, it works well.
Frequently Asked Questions
Can I bring a boat to Mirror Lake?
Yes. Small motorboats and canoes are allowed. There is no boat ramp, but you can hand-launch from the shore near the parking area. A boat lets you reach deeper water and quieter areas away from the bank, which can improve your chances on busy days.
What is the best time of day to fish Mirror Lake?
Early morning and late afternoon are most productive. Midday fishing is slower. Afternoon thunderstorms are common in summer, so plan to be off the water by 3 or 4 p.m. if the sky is building clouds. Evening fishing after a storm can be excellent if you stay safe.
Do I need to bring my own tackle, or can I rent or buy it in Kamas?
Bring your own. Kamas has a couple of small shops, but they do not stock a full range of tackle. Bring spinners, flies, and line before you go. If you forget something, you can drive back to Kamas, but it costs you fishing time.
Is Mirror Lake good for beginners?
Yes. The cutthroats are not picky, and the lake is forgiving. Beginners do well with small spinners and simple retrieves. The setting is beautiful and the campground is comfortable, so it is a good introduction to mountain lake fishing without the difficulty of a remote backcountry trip.
What should I do if I get caught in a thunderstorm?
Get off the water immediately. If you are in a boat, head to shore. If you are on the bank, move away from the water and seek shelter in trees or a vehicle. Do not stay in open areas or under isolated tall trees. Thunderstorms at high elevation are dangerous and can pass quickly, so wait it out and resume fishing when the sky clears.
