Located in Park County, Wyoming, Trout Lake is a lake at about 2,122 m (6,962 ft) above sea level. It lies in or next to Yellowstone National Park, so park hours, fees and rules apply. The nearest town is Livingston, about 91 km (57 mi) away (Trout Lake lies SSE of town).
Trout Lake, formerly known as Fish Lake and Soda Butte Lake, is a 12 acres (0.049 km2) popular backcountry lake for hikers and anglers in Yellowstone National Park. The lake is located approximately .33 miles (0.53 km) north of the Northeast Entrance Road near the confluence of Pebble Creek and Soda Butte Creek. The lake sits in a depression on a high bench above the Soda Butte Creek Canyon. A steep trail through a Douglas fir forest leads to the lake. The trailhead is located at: 44°53′57″N 110°7′21″W. Trout Lake is a popular area for viewing North American river otter.From the Wikipedia article “Trout Lake (Wyoming)”, licensed under CC BY-SA 4.0.

Lakes reflect best in calm air — usually the first hour after sunrise, before breezes ripple the surface.

Milky Way & night sky
From Trout Lake, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 3.2 hours on a moonless night), and the core peaks around 16° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.93 mag/arcsec². Aurora needs roughly Kp 5.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 39% average cloud cover) and February as the cloudiest (77%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lake
- Include shoreline rocks, reeds or a log as foreground to give the reflection depth.
- Expose for the brighter sky; reflections are typically half a stop to a stop darker.
- After sunset, long exposures smooth wind ripples into glass.
- For mirror reflections, get low and close to the water; the reflection grows with a lower camera.
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Autumn mornings bring mist and fall color; high-elevation lakes are usually ice-free only from early summer to mid-autumn.
Suggested gear: Tripod, Circular polarizer, Wide-angle lens, Waterproof boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
