Washita National Wildlife Refuge is a national wildlife refuge in Custer County, Oklahoma. It sits roughly 26 km (16 mi) NNE of Elk City.
Washita National Wildlife Refuge is a National Wildlife Refuge (NWR) of the United States located in Custer County, Oklahoma. Created in 1961 on the shore of Foss Lake, it was the fourth NWR in the state. It is 5 miles (8.0 km) west of Butler, Oklahoma. Within the refuge, the slow-moving Washita River winds through prairie and cropland to merge with Foss Reservoir, providing a home and resting area for geese and other waterfowl. Gently rolling hills, ravines, and bottomlands laced with creeks shelter wildlife as common as white-tailed deer and as unusual as the Texas horned lizard, a state-listed endangered species. The United States Fish and Wildlife Service has reported 270 bird species as having been seen in the NWR. These include occasional sightings of the bald eagle and rare sightings of whooping cranes. Outdoor activities allowed in the NWR include birdwatching, boating,...From the Wikipedia article “Washita National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Washita National Wildlife Refuge, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.8 hours on a moonless night), and the core peaks around 26° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 39% average cloud cover) and February as the cloudiest (52%). 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.
