USGS Ecosystems Fisheries: Aquatic and Endangered Resources Program Research Fish Passage and Dams

Fish Passage and Dams

USGS research assesses and evaluates management efforts to improve fish passage for anadromous and other migratory fish. Research focuses on fish physiological and behavioral characteristics as well as hydrological conditions that affect successful navigation around barriers by fish and other at-risk aquatic species. The research examines the efficiency and effectiveness of artificial passage structures to improve their design and effectiveness
