Learn about the ecology of aquatic organism passage (AOP), barrier analysis and passage design methods, techniques for providing passage at dams and road-stream crossings, and 2006 changes in the Fish Passage standard (Code 396) and its attendant measurement.
Many aquatic animals in the United States migrate within and between fresh and salt water environments at some time during their life. However, water development activities, transportation corridors, and a number of other practices often result in structures or management actions that pose passage challenges in estuaries, large rivers, and small streams. Viewers of this webinar will gain insight into contemporary issues in river and passage ecology through a discussion of the geographic extent and range of species exhibiting some sort of passage need throughout their life history, as well as reasons for migration or movement. Passage physiology is discussed, as well as numerous barrier evaluation methodologies, internet tools, and software that provide answers to important reconnaissance and design questions. Participants learn how to incorporate biology into fish passage design while accounting for site-specific geomorphic and hydrological factors. Passage tools covered include culverts (e.g., hydraulic, no slope, and stream simulation designs), instream structures (e.g., pool and weir fishways, rock ramps), tidegates, fish ladders (e.g., Alaska steeppasses and denils), and eel and elver passes. Finally, changes to CPS 396 are highlighted, and recent policy regarding measurement guidance for activities completed under CPS 396 is explained.
