Lake Seymour is a lake in Orleans County, Vermont at about 390 m (1,280 ft) above sea level. It sits roughly 18.1 km (11.2 mi) ESE of Newport.
Seymour Lake is located in the town of Morgan in Orleans County, Vermont, United States, an area known as the Northeast Kingdom. The lake was named for Israel Seymour, one of the original grantees. Natives called it Namagonic ("salmon trout spearing place"). The lake is on a tributary of the Clyde River in Orleans County, Vermont. It is one of only two deep, cold, and oligotrophic lakes in the Clyde River system, the other being nearby Echo Lake. The closest major airport is located in Burlington, Vermont, located approximately 101 miles away.From the Wikipedia article “Seymour Lake (Vermont)”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Lakes reflect best in calm air — usually the first hour after sunrise, before breezes ripple the surface.

Milky Way & night sky
From Lake Seymour, 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 2 (typical truly dark 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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.84 mag/arcsec². Aurora needs roughly Kp 4.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 56% average cloud cover) and December as the cloudiest (78%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lake
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- Mist often lifts off lakes on cold mornings after warm days, especially in autumn.
- 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.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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.
