About Conboy Lake National Wildlife Refuge - The Conboy Lake National Wildlife Refuge consists of approximately 5,800 acres of wetlands, lakebed, and surrounding uplands of the originally proposed 10,000 acres. Seasonal runoff from Mt. Adams floods several thousand acres in late winter. In the winter, you will find tundra swans, Canada geese, ducks, and bald eagles. This refuge is also one of three known nesting areas for sandhill cranes in Washington.
