Bypass fishway – Planning and design
Select from the tabs below
In addition to the general information for all fishway types, the following applies to bypass fishways.
The gradient of bypass fishways is typically 1:50 (vertical:horizontal), however some newer hybrid designs have been successful with a gradient of 1:40 (Andrew Berghuis pers comm.). Resting pools are typically used for every 1 m rise in vertical elevation and some designs include oversized resting pools with a range of habitats that provide habitat complexity, and associated protection from predation and resting habitat for all expected species and size classes (Andrew Berghuis pers comm.).
