Dam Submergence Flows: An Environmental Flow Prescription Designed to Aid Migratory Fish Passage

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As part of a holistic ecosystem‐focused set of unified flow prescriptions, natural spring flood events were enhanced with releases from an upstream reservoir on the Cape Fear River in North Carolina (USA) to submerge a series of low‐use, low‐head lock‐and‐dam structures for anadromous fish to move upstream.

Reviewing the Potential for Behavioral Guidance to Improve Downstream Passage of Out‐Migrating Anguillid Eels

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydroelectric dams and their turbine infrastructure threaten out‐migrating anguillid eels en route to marine spawning grounds. For decades, invested parties have attempted to guide eels away from turbines and toward safe passage routes. A subset of this work (hereafter behavioral guidance) has involved exploiting sensory biology (e.g., sight ...
