Located in Essex County, New York, Henderson Lake is a lake at about 553 m (1,814 ft) above sea level. It sits roughly 19.1 km (11.9 mi) SSW of North Elba.
Henderson Lake is located in the Adirondack Mountains in the town of Newcomb, Essex County, New York in the United States. It was named in 1826 after David Henderson, one of the founders of the Elba Iron Works near Lake Placid, New York, and of the Upper Works at Tahawus, New York. The lake is mainly cited by cartographers as the place where the Hudson River as named officially begins, flowing out of the eastern end and outlet of the lake. Unofficially, the source of the river is traced up Indian Pass Brook and other watercourses to Lake Tear of the Clouds.From the Wikipedia article “Henderson Lake (New York)”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Henderson Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.7 hours on a moonless night), and the core peaks around 17° 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 ≈ 21.77 mag/arcsec². Aurora needs roughly Kp 4.5+ 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 55% average cloud cover) and December as the cloudiest (83%). 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
- 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.
- 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.
- Check road and trail conditions with the managing agency before you go.
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.
