Half a million snow geese and a sunken steamboat share this Iowa refuge

It’s on the Missouri River border

DeSoto National Wildlife Refuge sits right where Iowa meets Nebraska, about 25 miles north of Omaha along the Missouri River.

The refuge covers 8,365 acres of bottomland forest, tallgrass prairie, and wetlands, all built around a seven-mile-long oxbow lake that used to be a bend in the river itself.

The Army Corps of Engineers straightened the channel in 1960, and the old curve filled in to become DeSoto Lake. What flies over it every year, and what sits buried beneath it, makes this place worth the drive.

Lewis and Clark camped here in 1804

William Clark wrote about this stretch of river on Aug. 3, 1804, noting the wildlife and recording the expedition’s first sighting of a badger.

The river bend later took its name from the nearby town of DeSoto, Neb., a busy steamboat stop through the 1800s.

By 1958, conservation groups and the federal government had stepped in to protect the floodplain for migratory birds along the Central Flyway.

The refuge now also supports endangered species like the pallid sturgeon, piping plover and least tern.

Watch thousands of white birds lift off at once

DeSoto draws snow geese by the hundreds of thousands every spring and fall. Fall runs from late October through early December.

In peak years, as many as half a million have stopped here to rest and feed on their route between Arctic nesting grounds in northern Canada and wintering areas along the Gulf Coast. Spring migration hits its peak in early March.

During big migration events, thousands of geese launch off the water at the same time, and the sound alone carries across the refuge.

Bald eagles perch in the cottonwoods along the lake

The eagles follow the geese in. As many as 145 bald eagles have been counted at the refuge at one time, and many stick around through winter into March.

You can spot them perched in the cottonwood trees that line DeSoto Lake. Fall also brings 75,000 or more ducks, mostly mallards, crowding the water.

Mixed in with them you’ll find Canada geese, northern pintails, wood ducks, trumpeter swans and several species of diving ducks working the deeper stretches of the lake.

Orioles and warblers take over in summer

The refuge bird checklist runs at least 240 species deep.

Spring and summer fill the trees with orioles, dickcissels, yellow warblers and red-headed woodpeckers.

Great blue herons wade through the wetlands in the warmer months. When fall rolls around, warblers, shorebirds and gulls pass through from September into October.

The mix of bottomland forest, grassland and wetland across the refuge creates enough variety in habitat to keep different species coming through all year long.

Deer, turkeys and morel mushrooms along the roads

About 30 mammal species live on the refuge, including white-tailed deer, beavers, coyotes and fox squirrels. Show up at dawn or dusk in early summer and you’ll likely see does with fawns browsing along the roads.

Wild turkeys gather in big groups near the fields, and cottontail rabbits, raccoons, opossums and muskrats make regular appearances.

If you visit in spring, you can forage for morel mushrooms in the open areas of the refuge and take them home for personal use.

A steamboat sank here in ten minutes flat

On April 1, 1865, the steamboat Bertrand hit a submerged log in the Missouri River and went down in less than 10 minutes.

The boat had been hauling supplies from St. Louis to gold miners in Montana Territory. Every passenger and crew member survived, but the cargo disappeared into the muddy river bottom.

It stayed buried for over a century until two Omaha treasure hunters, Sam Corbino and Jesse Pursell, located the wreck in 1968. Because it sat on federal land, every artifact went to the U.S. Fish and Wildlife Service.

River mud preserved roughly 250,000 artifacts pulled from the Bertrand wreck.

You can walk through the museum and see clothing, tools, household goods and mining equipment that look like they went into the water last week, not 160 years ago.

Boots, coats, canned food, oil lamps and French mustard jars all sit on display. The Bertrand site earned a spot on the National Register of Historic Places in 1969.

A short trail near the visitor center takes you to the excavation site, where the hull still rests buried underwater.

Four trails wind through forest, prairie and wetland

Each of the refuge’s four hiking trails puts you in a different habitat.

The Cottonwood Trail runs through bottomland forest where deer and turkey regularly cross the path. Over on the Grassland Trail, restored prairie opens up with views across DeSoto Lake.

The Bertrand Excavation Site Trail covers a quick quarter mile around the pond where the steamboat hull sits below the surface.

The Green Heron Trail loops around a restored wetland thick with frogs, birds and monarch butterflies in the summer months.

Paddle the oxbow lake from April through October

DeSoto Lake opens for kayaking, canoeing and no-wake boating from April 15 through Oct. 14.

You can launch from the Middle Boat Ramp or the South Gate Recreation Area. The no-wake rule keeps the water calm, so paddling along the shoreline is smooth and quiet.

The lake holds crappie, largemouth bass, bluegill and catfish if you want to drop a line. When winter sets in, ice fishing opens up in January and February as long as conditions allow it.

Bird feeders right outside the museum windows

The DeSoto Visitor Center holds the Bertrand Steamboat Museum and wildlife exhibits under one roof. Staff stock bird feeders outside the building every day, so you get easy birdwatching right from the windows.

Kids can work through the self-guided Junior Refuge Manager Program while you explore the displays. Refuge rangers run programs throughout the year on nature topics.

Picnic tables sit at the visitor center, trailheads and along Lakeview Drive, so you can pack a lunch and stay a while.

Visit DeSoto National Wildlife Refuge in Iowa

You’ll find DeSoto National Wildlife Refuge at 1434 316th Lane in Missouri Valley, Iowa, right off U.S. Highway 30 between Missouri Valley and Blair, Neb., about 25 miles north of Omaha.

The refuge grounds open daily from half an hour before sunrise to half an hour after sunset.

The visitor center and Bertrand Museum keep Tuesday through Saturday hours, 8:30 a.m. to 4:30 p.m., and close on federal holidays. Entry runs $3 per vehicle, and federal recreation passes work too.

Check the official website before you go, because some roads and trails close from mid-October through mid-April for migrating birds.
