The Science of River Restoration
Open Rivers Fund follows a path carved, in large part, by the current scientific understanding of river health.
Thanks to decades of dam removal data, scientists and engineers can increasingly predict what will happen when a dam is removed. The hydraulics of dam removal are well understood.
The greater scientific challenge, at this point, is in better understanding how river biology changes when barriers, large and small, are removed from rivers and streams.
To this end, Open Rivers Fund supports projects and organizations conducting research on river conditions before and after removal. Longitudinal data is best for assessing change, but even a single baseline survey is a valuable starting point.
We respect and support the work of Native American Tribes in restoring rivers and watersheds. Traditional Ecological Knowledge practiced by Indigenous communities for millennia is an important strategy for restoring river life.
Citizen Science Benefits Rivers and Communities
Multiple Open Rivers Fund projects involve investments in citizen science efforts to monitor river conditions, boost community understanding of science, and build community support. Growth in this field is important – and remarkable.
Local organizations are successfully engaging volunteers of varying levels of scientific knowledge and experience: scientists with advanced degrees, high school students, seniors, and all kinds of people in between. At the outset of any citizen science project, volunteers are developing processes and protocols to ensure accurate data is collected and analyzed in formats sharable with regulators and the public. In many cases, data quality standards are ratcheting upward.
Monitoring river conditions can be expensive. Volunteer citizen scientists expand the capacity to collect valuable data and document change following dam removal. As importantly, this work can create a lifelong connection to the river and the life it supports. Citizen scientists on the river often become life-long advocates for river health.

Patterns, drivers, and a predictive model of dam removal cost in the United States
Scientists have analyzed more than 650 dam removal projects over 55 years in the United States totaling $1.52 billion inflation-adjusted dollars to develop a tool to better estimate the cost of future dam removals.
Get ResourceDecision‐Support Framework for Dam Removal Planning
Given the several thousand dam removals expected over the coming decades, a systematic approach to plan future dam removals holds potential for aligning and delivering multiple benefits. This research presents a decision-support framework to prioritize dam removals based on opportunistic factors, hydro-ecological variables, and socio-cultural considerations.

Get ResourceDam Removal and River Restoration
This paper discusses dam removal by focusing on the importance of rivers as providers of vital ecosystem services like food, energy, and water. Dams are the most prevalent agents of change to the world’s rivers. The vast majority of the world’s estimated 16 million dams are relatively small, less than 10 meters in height.
