Inhaltsangabe

Fishway Capacity at Bonneville Dam: Measurements and design lessons from 1957 tests of small fishways reveals how researchers tested smaller fish corridors to see how many fish can pass per minute without crowding.

This report covers the 1957 Bonneville experiments, detailing the test setup, procedures, and observed results that inform more economical fish-passage designs.

The study focuses on how entry rate, pool space, and fish behavior influence the capacity of a fishway. It describes the test fishway that used six pools and specific design changes, such as reducing width and updating the weir crest to stabilize flow. The work also examines how different species and seasonal conditions affect ascent times and maximum passage.

• Learn how the test facility was arranged, including pool dimensions, flow rate, and lighting conditions used to observe fish passage.
• See how capacity was assessed by linking entry rate, pool occupancy, and movement speed, and how these factors interact to limit throughput.
• Explore the role of fish density, species mix, and environmental factors in shaping observed results and interpretations.
• Understand why researchers believed the capacity to pass fish could exceed a practical threshold, and what that means for design decisions.

If you’re interested in the engineering side of fish passage, this edition offers practical insights from a focused field study, with implications for designing economical and efficient fish-passage facilities.
Ideal for readers of fisheries engineering and readers seeking historical design lessons for dam bypass systems.
