Swan Lake Nature Study Area is a lake in Washoe County, Nevada at about 1,499 m (4,918 ft) above sea level. It sits roughly 2.6 km (1.6 mi) N of Lemmon Valley.
The Swan Lake Nature Study Area (formerly called Lemmon Valley Marsh) is a small conservation area in Lemmon Valley, Nevada. It contains marsh, alkali mud flats, and high desert. The Lahontan Audubon Society describes it as "a nearly unspoiled wetland in the midst of suburban housing and warehouses" and designates it a Nevada Important Bird Area. It is a notable location for birding; over 150 species have been observed there.From the Wikipedia article “Swan Lake Nature Study Area”, 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.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Swan Lake Nature Study Area, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.8 hours on a moonless night), and the core peaks around 21° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

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: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 19.67 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 21% average cloud cover) and December as the cloudiest (62%). 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
- 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.
- 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.
- Bring a spare battery — cold weather and long exposures drain them fast.
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.
