Fish passage design for waterway structures – key requirements
Source: Kapitzke 2010, Culvert Fishway Planning and Design Guidelines
Fish passage » Provide for fish passage over range of fish migration flows in the stream » Provide suitable hydraulic conditions for fish – velocity, flow depth… » Provide flow continuity, fish pathway, attraction flows and exit conditions » Ensure adequate light and other suitable environmental conditions
Drainage, utility, stream integrity, environmental values, amenity » Minimise obstruction to flow to not adversely affect flooding / drainage » Minimise effects of debris accumulation and sediment deposition » Prevent flood / erosion damage & maintain structure / waterway integrity » Maintain natural flow regime, geomorphic and ecological processes » Protect riparian and instream habitat and provide for fauna connectivity » Provide for monitoring, access and maintenance of fishway facility » Avoid public health problems, provide for safety, maintain amenity
