The hydropower community is faced with a major environmental challenge: balancing safe fish passage with cost-effective facility operations. HydroPASSAGE is focused on providing information and tools to increase fish survival through turbines and other hydropower structures across the U.S. and around the world.
The HydroPASSAGE project builds upon over 25 years of DOE-supported basic and applied research to understand the impacts of hydropower on fish and develop environmentally friendly hydropower turbines. The tools and technologies developed under HydroPASSAGE use biological design criteria from scientific, validated predictions of impacts to fish from turbine passage. The hydropower industry applies HydroPASSAGE tools to reduce fish injury and mortality and to lower the regulatory costs of deployment.
The Hydropower Biological Evaluation Toolset (HBET) is a set of software tools that analyze hydraulic conditions and offer measurable estimates of the physical stressors that fish experience at hydropower dams.
