Lower Klamath National Wildlife Refuge (Klamath Basin)
The Klamath Basin straddling the California–Oregon border is one of the Pacific Flyway's great waterfowl crossroads, and Lower Klamath — established by President Theodore Roosevelt in 1908 as the nation's first waterfowl refuge — sits at its heart. The U.S. Fish & Wildlife Service notes that approximately 80 percent of the flyway's migrating waterfowl pass through the Klamath Basin on both spring and fall migrations, and peak waterfowl populations can reach 1.8 million birds. The basin also draws wintering bald eagles. For RVers it is a long, open auto-tour through flooded fields and marsh, with eagles overhead in winter. The refuge is day-use, so base near Klamath Falls or Tulelake.
Migration window
Spring and fall waterfowl migration (fall numbers typically build into late autumn); wintering bald eagles present in winter. Timing varies year to year with water conditions.
Flagship species
Waterfowl (ducks, geese, swans) · Bald eagles (winter) · Pacific Flyway · Auto-tour route
Where
Klamath Basin on the California–Oregon border; Lower Klamath NWR straddles the state line south of Klamath Falls, OR
Nearest RV base
Day-use only — the refuge has a wildlife-viewing auto-tour but no camping. Nearest RV bases are private RV parks and campgrounds around Klamath Falls, Oregon (about 20–25 miles north), and in the Tulelake, California area.
Plan it honestly
Waterfowl and eagle numbers vary year to year with water conditions and weather, and peaks are never guaranteed; fall waterfowl generally build into late autumn and eagles concentrate in winter. The refuge is day-use with an auto-tour route; no camping on site. Winter roads and weather in the basin can be harsh, so check conditions before towing in.
