Massawepie Lake is a lake in St. Lawrence County, New York at about 461 m (1,512 ft) above sea level. It sits roughly 14.8 km (9.2 mi) WNW of Tupper Lake.
Massawepie Lake is located in the town of Piercefield, in southern St. Lawrence County, New York, approximately 12 miles (19 km) southwest of the village of Tupper Lake, New York. The lake is also surrounded by the Massawepie Scout Camps. The name of the lake is of Iroquois origin, meaning "the beaver's lake". The outlet flows west into the South Branch Grass River.From the Wikipedia article “Massawepie Lake”, 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 Massawepie Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.5 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 ≈ 21.82 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
- 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.
