ABSTRACT. The Bear River is driven by a highly variable, snow-driven montane ecosystem and flows through a droughtprone arid region of the western United States. It traverses three states, is diverted to store water in an ecologically unique natural lake, Bear Lake, and empties into the Great Salt Lake at the Bear River Migratory Bird Refuge (BRMBR). People in the Bear River Basin have come to anticipate droughts, building a legal, institutional, and engineered infrastructure to adapt to the watershed's hydrologic realities and historical legacies. Their ways of understanding linked vulnerabilities has led to what might appear as paradoxical outcomes: farmers with the most legally secure water rights are the most vulnerable to severe drought; managers at the federal Bear River Migratory Bird Refuge engage in wetland farming and make unlikely political alliances; and, increased agricultural irrigation efficiency in the Bear River Basin actually threatens the water supply of some wetlands. The rationality of locality is the key to understanding how people in the Bear River Basin have increased their adaptive capacity to droughts by recognizing their interdependencies. As the effects of climate change unfold, understanding social-ecological system linkages will be important for guiding future adaptations and enhancing resilience in ways that appropriately integrate localized ecosystem capacity and human needs.

The Bear River Basin, which includes portions of Idaho, Utah, and Wyoming in the United States, has a dynamic history of human hydrologic adaptations in relation to a highly variable water supply. These adaptations are embedded in a geographical setting highly influenced by the legal, policy, and institutional contexts that govern allocation of water in this generally arid region. In response to several years of drought and a historically low water year in 2004, water users in the Bear River Basin tested the efficacy of the ''law of the river'' and innovative agreements that they had negotiated in recent years to help mitigate impacts related to water shortages. Three innovations were identified as being key to a successful response to the 2004 drought: 1) a precedent-setting voluntary settlement agreement, 2) technical work in river modeling and instrumentation, and 3) extraordinary communication strategies employed throughout the drought. Based on case study research and utilizing a ''ways of knowing'' theoretical framework, the authors report on an unfolding contemporary history of how people in the Bear River Basin have learned to deal with uncertainties and risks associated with both droughts and floods. Their story has important implications for the understanding of conflict and cooperation in water systems, management of transboundary waters, and the promotion of sustainable water resource governance.

Reallocation is often promoted as a response to water security dilemmas in the western United States. Water banking is a form of reallocation utilized in several states to facilitate temporary water rights transfers. This article frames and examines water banking’s potential influences on water security from a hydro‐social perspective through a case analysis of water banking policy in Utah. It analyzes the challenges of integrating the market‐based economic incentives of water banks with the legal precedents of the prior appropriation doctrine to reallocate water in overappropriated basins with hydrologically interdependent uses. Key‐informant interviews and focus groups were used to examine water security’s meaning to stakeholders and analyze how water banking could affect the water security of disparate users and uses at multiple scales. Stakeholders predominately saw water security as assurance in water quantity, but water security was further equated by participants with the legal protections afforded by water rights. Multiple complexities in water bank implementation are to be expected when multiscalar contexts are considered, including societal and hydrologic tradeoffs in settings with diverse and interconnected interests. Our research shows that examining the potential ramifications of water banking policy through stakeholder perspectives can reveal nuanced insights on individual and collective water security issues not only within Utah but other arid regions in general.
