Located in Grant County, Wisconsin, Upper Mississippi River National Wildlife and Fish Refuge is a national wildlife refuge. It sits roughly 10.8 km (6.7 mi) N of Guttenberg.

The Upper Mississippi River National Wildlife and Fish Refuge is a 240,000-acre (970 km2), 261-mile-long (420 km) National Wildlife Refuge located in and along the Upper Mississippi River. It runs from Wabasha, Minnesota, in the north to Rock Island, Illinois, in the south. In its northern portion, it is in the Driftless Area, a region of North America that remained free from ice during the last ice age. Certain parcels contained within the refuge were later transferred to the Driftless Area National Wildlife Refuge. The refuge is an important element of the Mississippi Flyway. It has many wooded islands, sloughs, and hardwood forests. The wildlife found here include the canvasback duck, tundra swan, white-tailed deer, and muskrat. Recreational activities include boating, hunting, fishing, and swimming. Refuge Headquarters are located in Winona, Minnesota, with district offices...From the Wikipedia article “Upper Mississippi River National Wildlife and Fish Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky

From Upper Mississippi River National Wildlife and Fish Refuge, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.0 hours on a moonless night), and the core peaks around 18° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

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 ≈ 21.73 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 46% average cloud cover) and December as the cloudiest (68%). 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.
