fish passage design

Fish passage design involves creating structures that enable fish to navigate around obstacles like dams or barriers in waterways. The goal is to allow fish to migrate upstream or downstream safely and efficiently, supporting healthy populations. Designs can include fish ladders, fishways, or bypass channels, which mimic natural river conditions and offer gradual, navigable routes. Properly designed fish passages consider water flow, depth, and orientation to reduce stress and injury. This process supports ecological health, maintains fish migration patterns, and balances infrastructural needs with environmental stewardship.
