Entrainment, Impingement, Mortality
Fisheries regulators and dam owners frequently require information to evaluate how fish entrainment losses through hydroelectric plants affect fishery resources, to support regulatory decisions affecting potential project operation or infrastructure changes. Although sometimes an empirical field study is required, often the issue can be more cost-effectively resolved through strategic use of literature-based desktop analyses.
Our team has over 20 years of experience and knowledge of fish entrainment and turbine survival issues including scoping and conducting empirical studies throughout the east, mid-Atlantic, Midwest and west, interpreting resulting data, and negotiating solutions with regulatory agencies. Many of these studies are regarded as setting industry and scientific standards. We understand how to use both surrogate desktop data and the experience in the field to understand how and when study results are realistic. We have managed and/or performed over 70 desktop and field entrainment studies for a multitude of clients. Our studies are consistently accepted by fishery resource agencies and FERC, and in some cases cited as industry models.
