Franz Lake National Wildlife Refuge

Franz Lake National Wildlife Refuge is the largest and most intact wapato and rush marsh remaining on the lower Columbia River and was established in 1990 to preserve biodiversity. Franz and Arthur lakes provide critical habitat for wintering tundra swans and other waterfowl. Several springs and seeps on the refuge have been identified as important brood and rearing areas for juvenile salmon. 

Staff and partners work to maintain and monitor these rare wetland and forested habitats. Knowledge gained through this research will contribute to the understanding to how the lower Columbia River floodplain can be managed. In keeping with this research and monitoring emphasis, human disturbance is kept to a minimum.
