Before and after photos of a culvert replacement project: The before picture (left) shows an undersized and 

 perched culvert, which caused channel instability and migration problems for small fish. The after photo (right) is 

 a larger baffled culvert set at stream grade to allow upstream passage of all fish, including juveniles. 



These photos show a culvert replacement project. The culverts were high velocity barriers to small fish. Bridges 

 allow unimpeded upstream fish passage, plus allows upstream movement of other species like amphibians, which 

 relv on natural stream bottoms.
