Lake Ophelia National Wildlife Refuge is a national wildlife refuge in Concordia Parish, Louisiana. The nearest town is Marksville, about 23 km (14 mi) away (Lake Ophelia National Wildlife Refuge lies ENE of town).
Lake Ophelia National Wildlife Refuge was established in 1988 to protect the Mississippi/Red River floodplain ecosystem. The refuge is located in Avoyelles Parish, Louisiana, east central Louisiana. The refuge is named for its most prominent water body, the 350-acre (1.4 km2) Lake Ophelia that was at one time a channel of the nearby Red River of the South.From the Wikipedia article “Lake Ophelia National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Lake Ophelia National Wildlife Refuge, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.5 hours on a moonless night), and the core peaks around 30° 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.
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 38% average cloud cover) and February as the cloudiest (61%). 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 national wildlife refuge
- Stay on designated routes and keep a respectful distance — if an animal changes behavior, you are too close.
- A 400–600 mm lens (or a crop body) is the usual tool for birds.
- Fast shutter speeds (1/2000 s+) freeze wingbeats; raise ISO rather than lose the shot.
- Migration peaks bring the largest concentrations — see the birding calendar for this state.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Spring and autumn migration are the highlights; winter brings waterfowl to many southern refuges.
Suggested gear: Telephoto lens (400 mm+), Bean bag for car window, Binoculars. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Launching or landing drones on National Wildlife Refuge lands generally requires a special use permit from the refuge manager, and wildlife disturbance rules apply everywhere.
