Culverts are Common Fish Passage Barriers
Culverts placed in streams for driveways, farm roads, or forest roads may function as barriers to fish passage. Salmon rely on fresh water streams to lay their eggs. When ideal upstream locations are blocked by things like culverts, they are limited in where they can spawn and grow.
Culverts can become a barrier when there is an excessive drop, a high velocity of water, too shallow of water in the culver, or the culvert is filled to the point of being in-accessible.
