Dams alter the geomorphology, water quality, temperature regime, and flow regime of lotic
systems influencing the resources and habitat of fish, benthic invertebrates, and lower …

Stream ecosystems are increasingly impacted by multiple stressors that lead to a loss of
sensitive species and an overall reduction in diversity. A dominant paradigm in ecological …

A substantial increase in fluvial sediment supply relative to transport capacity causes
complex, large-magnitude changes in river and floodplain morphology downstream …

One of the desired outcomes of dam decommissioning and removal is the recovery of
aquatic and riparian ecosystems. To investigate this common objective, we synthesized …

Environmental DNA (eDNA) has emerged as a potentially powerful tool for use in
conservation and resource management, including for tracking the recolonization dynamics …

The Elwha River dams have disconnected the upper and lower Elwha watershed for over 94
years. This has disrupted salmon migration and reduced salmon habitat by 90%. Several …

Like many rivers in the western US, the Elwha River, Washington, has changed substantially
over the past century in response to natural and human forcing. The lower river is affected by …

Flow regimes are a major driver of community composition and structure in riverine
ecosystems, and flow regulation by dams often induces artificially-stable flow regimes …

Dam removal is increasingly being recognized as a viable river restoration action. Although
the main beneficiaries of restored connectivity are often migratory fish populations, little is …

Large dams regulate river hydrology and influence water chemistry, sediment dynamics,
channel form and biotic communities. These effects may translate into important changes in …
