Passage Technologies for American Eels

The American eel (Anguilla rostrata) migrates into freshwater in the juvenile (glass eel and elver) stage, feeds and grows in freshwater habitats, and migrates downstream to the ocean to spawn as an adult. Migrating eels frequently encounter barriers in river environments, primarily in the form of dams, that limit access of juveniles to upstream growth habitat, and can injure or kill...

New England WSC Seminar series Barclay 20190724

Groundwater discharge zones supply baseflow, provide critical thermal refugia for aquatic organisms, and serve as point sources of nutrients and contaminants to aquatic ecosystems. Despite their importance, the spatial distribution and the water quality effects of groundwater discharge zones across river networks are seldom predicted at regional scales due to the highly spatially heterogeneous...

Water Quality Sampling and Monitoring of the Pawcatuck River Watershed

The Pawcatuck River and the Pawcatuck River Estuary and Little Narragansett Bay form part of the boundary between the States of Connecticut and Rhode Island. Both states have identified water quality impairments within these waters related to nutrients (insufficient oxygen) and bacteria. Studies of the eutrophication potential of Long Island Sound embayments have identified that the Pawcatuck...
