Beaver dams: A free conservation practice for water quality enhancement?
Beaver activity (i.e., damming of streamflow) holds significant potential to impact water quality, specifically in-stream nutrient processing.
A Critical Review of the Effects of Beavers Upon Fish and Fish Stocks
A review by the University of Southampton of how the reintroduction of beaver will affect fish in Scotalnd
Qualitative and Quantitative Effects of Reintroduced Beavers on Stream Fish
Review of research about the positive and negative effects of beaver towards fish
Ecology, management, and conservation implications of North American beaver (Castor canadensis) in dryland streams 2014
A review that suggests that beaver activity can create substantial benefits and costs for conservation
Euro-American Beaver Trapping and Its Long Term Impact on Drainage Network Form and Function, Water Abundance, Delivery, and System Stability
Examines the long-term impact of historic beaver trapping in the United States on stream systems, the role of beaver trapping in arroyo formation in the American Southwest, why the significance of beavers was missed by the U.S. General Land Office surveys in the late 1700s to mid 1800s, and how that oversight impacted later researchers in the 1950s and 1960s as the study of fluvial geomorphology and hydraulic geometry emerged.

Impacts of beaver dams on hydrologic and temperature regimes in a mountain stream
This study quantifies the impacts of beaver on stream hydrologic and temperature regimes, and highlights the importance of understanding the spatial and temporal scales of those impacts. We explored the impacts of beaver dams on hydrologic and temperature regimes at different spatial and temporal scales within a mountain stream in northern Utah over a 3-year period spanning pre- and post-beaver colonization.
Influence of rainfall and beaver dams on upstream movement of spawning Atlantic salmon in a restored brook in Nova Scotia, Canada 2009
Study of how beaver dams and their effect on stream flow affect Atlantic Salmon
Laws, regulations, and management plans to improve streamflow and stream temperature : a case study in the North Fork Burnt River Watershed
This project explored the effectiveness of a management plan on improving streamflow and stream temperature
Meta-analysis of environmental effects of beaver in relation to artificial dams
An analysis between the differences of beaver dams and artificial dams and their impacts on the wetlands they occupy
The Economic Value of Beaver Ecosystem Services Escalante River Basin, Utah 2001
In-depth report on how beaver could provide benefits to local residents and visitors well into the millions of dollars per year in Utah.
Ecological engineering and aquatic connectivity: a new perspective from beaver-modified wetlands, 2014
This study demonstrated that beavers actively increase the volume-to-surface area ratio of wetlands by almost 50% and that their digging of foraging channels increases average wetland perimeters by over 575%. They concluded that exclusion or removal of beavers could limit ecosystem processes and resilience.
Human-made Beaver Dams Likely Save Natural Wetland from Extinction
The U.S. Dept. of the Interior, Bureau of Land Management blog reports that in arid, high country Oregon, a series of manmade beaver dams (Beaver Dam Analogs) have created a watery oasis.
Project: Hydrological Impact of Beaver Habitat Restoration in the Milwaukee River Watershed
A comprehensive study evaluating how restoring beaver dams could significantly protect the city of Milwaukee from future flood vents and the significant cost savings of this nature-based management approach versus traditional flood prevention engineering.
Interactions between climate change and beavers in coastal streams
This project investigated the effects of climate on multiple aspects of river hydrology, including the interaction with expanding beaver populations in the Northeast. Our findings suggest that beavers increase water retentions, and sometimes flooding, in rivers which increases nitrogen removal.
Could beaver compete with a declining snowpack?
To estimate the extent to which beaver dam building activity could provide transient water storage with a decreased snowpack.

Impact of beavers regarding drought and wildfire in the Methow River Watershed
Smokey the Beaver: beaver-dammed riparian corridors stay green during wildfire throughout the western USA
Study of how beaver ponds make nearby vegetation more resilient towards wildfires
Beaver: Nature’s ecosystem engineers
This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.
