Rivers are vital for sustaining biodiversity and human development, yet globally only a small fraction of rivers enjoy protection and those with protections are often impaired or modified. Rapid rates of freshwater species’ extinctions indicate current conservation practices are failing. Despite over fifty years of scientific evidence justifying river conservation, it remains that less attention is focused on protecting ecosystems than on developing water resources for economic growth. This disparity is indicative of the ‘nature as resource’versus ‘conservation of nature’paradigm. Today, this paradigm is complicated by new attentions centering both on water resource development projects and conservation policy as climate change adaptation strategies. Policies protecting rivers are recommended for contending with more intense storms and flooding, increasing resilience for species, forests, and agricultural areas, and fostering some types of water security. Creating, implementing, and managing climate adaptation policies will require a strong state presence in water resource governance. We know, however, the aforementioned paradigm hinders conservation policymaking. Therefore, understanding how conservation policy has already been rationalized, implemented, and managed is critical to advancing climate adaptation policymaking. Yet, little empirical research has been conducted on federal river conservation policy creation or application across the US
