Medicine Lake National Wildlife Refuge was established in 1935 — one of hundreds of refuges created during the Dust Bowl and Great Depression era as the federal government responded to the ecological catastrophe of draining wetlands across the northern plains.
The 31,000-acre refuge in Sheridan County preserves a complex of lakes, wetlands, and grasslands that serves as one of the most important breeding and staging areas for colonial waterbirds in the northern Great Plains.
The American white pelican colony here is extraordinary. More than 2,000 pelicans nest annually on the refuge’s islands — one of the largest inland pelican colonies in North America.
That number requires calibration: a single American white pelican weighs 10–20 pounds, has a 9-foot wingspan, and requires roughly 4 pounds of fish per day.
A colony of 2,000 birds represents an enormous biological event — a sustained presence of thousands of massive white birds visible for miles across the open water.
TL;DR
- Medicine Lake (~230) is a small Sheridan County community adjacent to Medicine Lake National Wildlife Refuge — one of the most important colonial waterbird nesting sites in the northern Great Plains.
- 2,000+ American white pelicans nest annually — one of North America’s largest inland pelican colonies.
- Additional nesting species include double-crested cormorants, great blue herons, black-crowned night herons, and dozens of duck species.
- The 10-mile auto tour route allows wildlife viewing without disturbing nesting.
- Best for: birders, wildlife photographers, waterfowl hunters, and anyone wanting world-class wildlife access in remote northeastern Montana.

What Makes Medicine Lake Different
The scale of the pelican colony puts Medicine Lake NWR in a specific category of wildlife experience. Seeing 10 pelicans on a lake is a pleasant bird sighting; seeing 2,000 pelicans — their white forms visible from miles away, the noise of the colony audible from the auto tour road, the constant traffic of adult birds leaving and returning from fishing trips — is a genuinely overwhelming wildlife spectacle.
The refuge was created specifically to counter the Dust Bowl-era pattern of wetland destruction. The northern plains’ pothole lakes and seasonal wetlands, formed by glaciation and maintained by snowmelt and rainfall, were being drained at a rapid rate in the early 20th century as farmers tried to maximize cropland.
The ecological consequences were severe — waterfowl populations crashed, colonial waterbird nesting sites disappeared, and the biodiversity of the northern plains declined dramatically.
Medicine Lake’s preservation maintained a critical refuge that both resident and migratory species depend on. The pelican colony, the cormorant rookery, the great blue heron nesting areas, and the duck nesting habitat all represent what northern plains wetlands looked like before drainage. The contrast between the refuge’s biological richness and the surrounding agricultural landscape is striking.

The Top 10 Things to Do
1. Auto Tour Route (10 miles)
The refuge’s auto tour gives access to the primary viewing areas — the pelican colony on Berge Island, the cormorant nesting area, and the main lake’s waterfowl concentration.
The tour covers approximately 10 miles on gravel roads passable in most vehicles. Windows-down driving allows the sounds of the colony to register — the noise of 2,000 pelicans is significant.
Practical: Contact the Medicine Lake NWR visitor contact station for current road conditions and colony status. The tour is open during daylight hours. Free.
2. Pelican Colony Viewing
The pelican nesting colony on Berge Island is visible from the auto tour road — binoculars are sufficient for the main colony; a spotting scope significantly improves the detail.
Peak nesting activity is May through July; young birds are visible in late July and August. By September, the colony begins dispersing as birds move south.
3. Cormorant and Heron Nesting
Double-crested cormorants nest in the same general area as the pelicans — a mixed colonial waterbird nesting site with multiple species using different sections of the island. Great blue herons nest separately, with a colony visible from different points on the tour route.
4. Spring Migration Birding (March–May)
Spring migration brings extraordinary concentrations of waterfowl — pintail, mallard, canvasback, ring-necked ducks, and dozens of other species stage at Medicine Lake before moving north. The refuge can hold tens of thousands of ducks and geese during peak migration.
5. Fall Migration (August–November)
After breeding season, the refuge hosts fall staging waterfowl in significant numbers. Shorebird migration in August and early September is an additional draw — western and pectoral sandpipers, yellowlegs, dowitchers, and phalaropes use the lake margins.
6. Waterfowl Hunting (Fall)
Portions of the refuge open to waterfowl hunting in fall — check current FWS regulations for hunting zones, dates, and species. This is a significant regional hunting destination.
7. Hiking the Refuge Grasslands
The grassland portions of the refuge provide hiking opportunities through mixed-grass prairie — good birding for grassland species including Sprague’s pipit, Baird’s sparrow, and chestnut-collared longspur.
8. Photography
The Medicine Lake colony is one of the best wildlife photography opportunities in northeastern Montana. Morning light on the lake, pelicans launching and landing, the scale of the colony — experienced wildlife photographers make specific trips to Medicine Lake for this subject.
9. Day Trip to Plentywood (25 min southwest)
Communist Party era history, Brush Lake State Park. See Plentywood guide.
10. Connecting the Montana Refuges
Medicine Lake fits into a broader Montana and northern plains wildlife refuge system. Connecting it with Freezout Lake (near Fairfield/Choteau, much further west) and Ninepipe/Pablo NWRs (Ronan area) gives a sense of the statewide wetland conservation network.
Where to Stay
No lodging in Medicine Lake town. Plentywood (25 min southwest) is the practical base.
| Hotel | Vibe | Price | Best For |
|---|---|---|---|
| Plentywood motels (25 min southwest) | Basic local range | $85–140 | Most travelers |
Where to Eat

Getting There
From Plentywood: 25 miles northeast via MT-16 and county roads, about 30 minutes.
From Culbertson: 35 miles northwest, about 40 minutes.
For the auto tour: From the refuge entrance sign on MT-16 north of Medicine Lake town, follow the refuge access road.
When to Visit
May–July: Peak pelican nesting activity; colony at maximum size and activity.
August: Young pelicans visible; fall shorebird migration begins; hunting season approaches.
March–May: Spring waterfowl migration — can rival the fall in spectacle.
Fall (September–November): Waterfowl hunting season; fall staging birds.
Personal Tips
Binoculars are essential. The minimum equipment for a meaningful Medicine Lake NWR visit. A spotting scope on a tripod significantly improves the colony viewing.
Contact the refuge before visiting. Current road conditions, colony status, and wildlife activity vary — the FWS station can give a meaningful preview.
Allow a full morning. The auto tour plus quality time at viewing areas takes 2–3 hours minimum for a satisfying wildlife experience.
The noise is part of the experience. The sound of 2,000+ pelicans — the wing beats, the vocalizations, the splashing — is as impressive as the visual spectacle.
