Abstract
Minimizing obstructed fish passage through culverts is an important step that an engineer must take when designing and installing culverts. This process will often require consultation with a fish biologist to ensure that all fish passage considerations are recognized. The existing research is reviewed and synthesized. A good set of recognized guidelines to be used to design culverts for roads in rural areas is provided.
