Located in McHenry County, North Dakota, Wintering River National Wildlife Refuge is a national wildlife refuge. It sits roughly 18.4 km (11.4 mi) SE of Velva.
Wintering River National Wildlife Refuge is a National Wildlife Refuge in McHenry County, North Dakota. It is managed under J. Clark Salyer National Wildlife Refuge. This is a limited-interest national wildlife refuge. The FWS has an easement on private property allowing it to manage wildlife habitat, but the land remains private property. There is no public access although wildlife may be observed from adjacent public roads. Limited-interest refuges were created in the 1930s and 1940s in response to declining waterfowl populations and the need to get people back to work during the Great Depression. Many landowners sold easements allowing the federal government to regulate water levels and restrict hunting.From the Wikipedia article “Wintering River National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Wintering River National Wildlife Refuge, the Milky Way core is visible in a dark sky from April through July. June gives the longest window (about 1.3 hours on a moonless night), and the core peaks around 13° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky 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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.91 mag/arcsec². Aurora needs roughly Kp 3.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 47% average cloud cover) and December as the cloudiest (69%). 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.
- Use auto-loop roads as mobile blinds; animals often tolerate vehicles more than people on foot.
- 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.
