Abstract We quantified fish assemblages in 20 streams containing mill dams in various physical conditions (dams intact, partially breached, or relict with normal flows) in Alabama, USA, during the period from 2006 to 2008. We used a backpack electroshocker to sample three 150-m reaches per stream: 500 to 1000 m downstream of the dam, 0 to 100 m downstream of the dam, and 100 m upstream of the impoundment. Species- and trait-based analyses revealed slightly different, but often complementary… 
Associations between small dams and mollusk assemblages in Alabama streams
Abstract Small dams are ubiquitous yet poorly understood features in many streams. Dam removal is being used increasingly in stream restoration projects as a means to enhance habitat connectivity and
Effects of Small Dams on Freshwater Bivalve Assemblages in North Carolina Piedmont and Coastal Plain Streams
Small dams represent one of the most widespread human alterations to North American streams, yet effects on bivalve assemblages are understudied. Dams are quickly being removed and prioritizing dams
Effects of small dam condition and drainage on stream fish community structure
Low-head dams are ubiquitous in eastern North America, and small dam removal projects seek to improve habitat conditions for resident and migratory fishes. Effects of small dams of varying status on
When to sample: flow variation mediates low-head dam effects on fish assemblages
Low-head dams are a primary source of anthropogenic disturbance to river systems. They have the ability to change rivers from lotic to lentic habitats, affect sediment transportation, connectivity,
Variation in fish assemblages across impoundments of low-head dams in headwater streams of the Qingyi River, China: effects of abiotic factors and native invaders
TLDR
This study suggests that the combination of changes in abiotic factors and biotic structure and process following dam-building may determine the indigenous fish assemblages in the impoundments of low-head dams within headwater streams.
Effects of Small Dams on Sunfish Assemblages in North Carolina Piedmont and Coastal Plain Streams
TLDR
Examination of sunfish assemblages at 75 sites associated with small dams in the Neuse, Tar, and Roanoke drainages in North Carolina shows that streams with intact dams would have more introduced centrarchids than streams with breached or relict dams in response to dam-induced shifts in assemblage structure.
The Effects of Low-Head Dams and Land Use Change on North Carolina Atlantic Slope Fish Community Structure
Dams impound streams, alter sediment regimes and other physicochemical characteristics, and fragment populations. Low-head dams are ubiquitous in eastern North America and impact communities across
Fish Assemblage Response to a Small Dam Removal in the Eightmile River System, Connecticut, USA
TLDR
It is concluded that dam removals can have positive benefits on fish assemblages by enhancing river connectivity and fluvial habitat availability and restoring river connectivity for fish movement.
Low‐Head Dam Impacts on Habitat and the Functional Composition of Fish Communities
The natural flow regime of many rivers in the USA has been impacted by anthropogenic structures. This loss of connectivity plays a role in shaping river ecosystems by altering physical habitat

Increased awareness of the negative effects of dams combined with an aging dam infrastructure has led to an increase in dam removals. However, ecological responses of downstream biota to such actions
Short-Term Changes in Channel Form and Macroinvertebrate Communities Following Low-Head Dam Removal
TLDR
D dam removal caused relatively small and transient geomorphic and ecological changes in downstream reaches, and apparently rapid channel development to an equilibrium form within the impoundment, associated with both dam removal and the subsequent June flood.
